CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/535,180 filed on Aug. 8, 2019. All sections of the aforementioned application are incorporated herein by reference in their entirety.

FIELD OF THE DISCLOSURE

The subject disclosure relates to an apparatus and method to facilitate an iterative, machine learning based traffic classification.

BACKGROUND

The ability to properly classify traffic on a network is an important aspect of maintaining and operating the network. For example, a proper classification of the traffic enables a network operator/service provider (e.g., access network providers, core network providers, cloud providers, and content delivery providers) to increase/enhance a quality of experience (QoE)/user experience in relation to services provided over the network, while simultaneously decreasing/reducing the number of network resources that are required/needed. In this respect, an ability to properly classify traffic on a network is an important parameter in relation to network efficiency and scale.

As networks continue to be placed into operational service or expanded, the amount of total traffic over such networks tends to increase. Thus, it is generally impractical/inefficient to manually examine every item of traffic that may traverse a network in order to classify each item. In this regard, a header of a traffic item may include metadata describing a class/category of the traffic item. This header may be examined via, e.g., a probe or other network element, in order to identify the metadata (and thus, the class/category of the traffic item). However, increasingly traffic is being encrypted prior to being transmitted/traversing a network in view of privacy considerations and in an effort to prevent unauthorized third-parties from accessing the traffic. Thus, network operators/service provides are unable to classify/categorize encrypted traffic items via the use of a probe or network element as set forth above.

Still further, a machine learning/deep learning (ML/DL) model-based approach has been suggested, whereby during a training/calibration phase labeled/tagged traffic traverses the network. Labels/Tags of the labeled/tagged traffic specify predefined categories/classes of traffic, such that a model is able to decipher/determine/learn patterns in traffic according to the specified category/class of the traffic. In subsequent phases, the model predicts a category/class of unlabeled/untagged traffic based on what the model learns during the training/calibration phase.

While effective in theory, the aforementioned model-based approach is ineffective in classifying unlabeled/untagged traffic in practical applications/environments due to at least: (1) cost considerations (e.g., a use of a limited number of labeled sets/items of traffic that are available during the training/calibration phase), and (2) the introduction of new or enhanced traffic (which may originate from new or enhanced applications) that the model classifies with poor results/accuracy.

Referring now to FIG. 1, a block diagram is shown illustrating an example, non-limiting embodiment of a communications network 100 in accordance with various aspects described herein.

FIG. 2A is a block diagram illustrating an example, non-limiting embodiment of a system 200a. The system 200a may function within, or be operatively overlaid upon, the communication network 100 of FIG. 1 in accordance with various aspects described herein. The system 200a may be used to categorize/classify traffic/traffic items that is/are present in one or more networks. As an illustrative example, the system 200a may be used to classify an item of traffic as a video item or a non-video item. Other categories/classifications may be used/provided/obtained in some embodiments.

For the sake of illustrative convenience/ease, the use/operation of the system 200a is described below in relation to FIG. 2B. FIG. 2B depicts an illustrative embodiment of a method 200b in accordance with various aspects described herein. One skilled in the art will appreciate, based on a review of this disclosure, that aspects of the method 200b may be executed/implemented/practiced in conjunction with systems, devices, and components beyond what is shown in FIG. 2A. Similarly, the system 200a may execute one or more methodological acts beyond what is described below in relation to FIG. 2B.

In blocks 204b and 208b, one or more models may be trained/established (block 208b) based on/responsive to obtaining items of labeled/tagged traffic (block 204). As part of block 204b, a counter (referred to hereinafter as a retry counter) may be initialized, illustratively to a value of zero. The role/function/purpose of the retry counter will become clearer in the disclosure that follows.

The labeled/tagged traffic of block 204b may identify a predefined category/class of the traffic. For example, as shown in FIG. 2A a model training component 202a may utilize/obtain as inputs items of labeled/tagged traffic 206a-1, 206a-2, 210a-1, and 210a-2. The traffic item 206a-1 may correspond to a first video traffic item and the traffic item 206a-2 may correspond to a second video traffic item. The traffic item 210a-1 may correspond to a first non-video traffic item and the traffic item 210a-2 may correspond to a second non-video traffic item.

Video traffic items may include audiovisual aspects, whereas non-video traffic items may, illustratively, include only audio aspects (e.g., audio tracks such as music, books on tape, etc.), only visual aspects (e.g., still-frame images), text, etc. In some embodiments, the non-video traffic items may adhere/conform to file transfer protocol (FTP) traffic and/or file-sharing data-based traffic. In general, traffic/traffic items may be communicated between a client and a server on a network, between peer devices on a network, between processors of a distributed computing/processing environment, etc. The tags/labels of one or more of the traffic items 206a-1, 206a-2, 210a-1, and 210a-2 may include an identification of a source (e.g., an originator and/or a distributor) of the respective traffic items 206a-1, 206a-2, 210a-1, and 210a-2.

While four labeled traffic items 206a-1, 206a-2, 210a-1, and 210a-2 are shown in FIG. 2A, in many embodiments the number/count of labeled traffic items may be different from (e.g., larger than) four in order to properly/sufficiently engage the model training component 202a. As part of block 208b, the model training component 202a may assess/analyze/identify patterns in the labeled traffic items (e.g., the labeled traffic items 206a-1, 206a-2, 210a-1, and 210a-2) in order to establish a relationship between those patterns and the categories/classes (e.g., video or non-video) of the labeled traffic items.

As part of block 208b, the model training component 202a may generate/establish a (working) model 214a in the first instance. Thereafter, the working model 214a may be used to categorize/classify an unknown/unlabeled traffic item (e.g., unlabeled traffic item 218a) as described further below. Following the establishment of the working model 214a in the first instance, the working model 214a may be updated/modified/refined as described further below.

In block 212b, the unlabeled traffic item 218a may be obtained. For example, the unlabeled traffic item 218a may be obtained based on the unlabeled traffic item 218a being transmitted from one or more sources via one or more networks/network elements/network infrastructure. The unlabeled traffic item 218a may be encrypted.

In block 216b, the model 214a may be applied to the unlabeled traffic item 218a. Assuming that the unlabeled traffic item 218a is encrypted, the model 214a may be applied to the unlabeled traffic item 218a as part of block 216b without decrypting the unlabeled traffic item 218. As part of block 216b, the model 214a (or another element/component) may identify parameters of the unlabeled traffic item 218a. The parameters may include: the number of bytes transmitted or received, potentially as a function of time (e.g., 10 bytes per timeslot in a first period of time, 25 bytes per timeslot in a second period of time, etc.), one or more server name indication (SNI) identifiers and/or domain name identifiers, a summary of (data of the) unlabeled traffic item 218a in terms of throughput and/or duration, etc.

In block 220b, and in response to the identification of the parameters in block 216b, the model 214a may generate a prediction 222a in terms of a category/classification of the unlabeled traffic item 218a. For example, as part of block 220b, the parameters of block 216b may be compared to the patterns identified in block 208b to select a category/class for the unlabeled traffic item 218a. In an exemplary embodiment, the unlabeled traffic item 218a may be classified as a video item or a non-video item as part of block 220b.

In block 224b, one or more scores may be generated by, e.g., the model 214a, in terms of the predicted category/class of block 220b. A score generated in block 224b may be representative of a confidence of the model 214a in terms of the prediction of the category/class in block 220b, and may be based on the comparison set forth above with respect to block 220b. For example, if the comparison of block 220b yields an exact or substantial match (e.g., a match that is greater than a threshold), confidence in the prediction of the category/class of the unlabeled traffic item 218a as part of block 220b may be ‘high’, whereas if the comparison of block 220b yields a poor match (e.g., a match that is less than a threshold), confidence in the prediction of the category/class of the unlabeled traffic item 218a as part of block 220b may be ‘low’.

In block 228b, a determination may be made whether the score/confidence of block 224b (and/or block 244b as described in further detail below) is greater than a first threshold. If so (e.g., the “yes” path is taken from block 228b), flow may proceed from block 228b to block 208b. Otherwise (e.g., the “no” path is taken from block 228b), flow may proceed from block 228b to block 232b.

As part of the flow from block 228b to block 208b, the unlabeled traffic 218a (of block 212b) may be treated similar to the labeled traffic (of block 204b) in terms of an update/refinement/modification of the model 214a via the model training component 202a. Stated slightly differently, as part of the flow from block 228b to block 208b, the unlabeled traffic 218a may effectively serve as another input (in addition to the labeled traffic items 206a-1, 206a-2, 210a-1, and 210a-2) to the model training component 202a, such that the model 214a generated/produced by the model training component 202a may be refined/modified/updated in accordance with the unlabeled traffic 218a. In this manner, the model 214a may be updated in accordance with traffic that has an associated ‘high’ degree of categorization/classification tied to it. In other words, the model 214a may be a ‘living’ model that is adapted over time as new/additional unlabeled traffic/traffic items is/are obtained. As the model 214a is refined over time, any error in terms of the prediction of the classification/categorization block 220b will tend to converge to zero; e.g., the model 214a will become more accurate the more the model 214a is used/exercised.

As part of the flow from block 228b to block 208b, the score/confidence of block 224b (or block 244b as described further below) may serve as a weight in terms of the refinement of the model that is obtained. For example, and assuming a score range from 1 to 100 (where 100 represents absolute certainty, e.g., the highest degree of confidence, and 1 represents the least degree of confidence), the labeled traffic of block 204b may be assigned a weight of 100. Thus, the extent or degree to which the model 214a is refined may be a function of the degree of confidence associated with an unlabeled traffic item. Unlabeled traffic items that have a high degree of confidence associated with them may more directly influence/impact the model than those unlabeled traffic items having a low degree of confidence associated with them.

In block 232b, a determination may be made whether the score/confidence of block 224b (and/or block 244b as described in further detail below) is greater than a second threshold (where the second threshold of block 232b is less than the first threshold of block 228b). If so (e.g., the “yes” path is taken out of block 232b), flow may proceed from block 232b to block 236b. Otherwise (e.g., the no” path is taken from block 232b), flow may proceed from block 232b to block 240b.

The flow from block 232b to block 240b may signify that the confidence/score is “so low” so as to not warrant additional analysis/use of computing resources. In other words, unlike the scenario described above in respect of the flow from block 228b to block 208b (wherein the unlabeled traffic 218a is used to update/modify/refine the model 214a due to the high degree of confidence associated with the prediction of the categorization/classification in block 220b), the flow from block 232b to block 240b may serve to ensure the integrity of the model 214a by ensuring that low-confidence predictions of the categorizations/classifications of block 220b do not influence/negatively impact the model 214a.

In block 236b, a determination may be made regarding whether the retry counter has a value that is greater than an associated threshold (referred to herein as a retry threshold). If so (e.g., the “yes” path is taken out of block 236b), flow may proceed from block 236b to block 240b. Otherwise (e.g., the no” path is taken from block 236b), flow may proceed from block 236b to block 244b.

The flow from block 236b to block 240b may be representative of a trade-off between attempting to incorporate the unlabeled traffic 218a (having an associated medium-valued confidence/score [e.g., a confidence/score between the first threshold of block 228b and the second threshold of block 232b] as generated in block 224b) as part of the model 214a on the one hand versus preserving resources and the integrity of the model 214a on the other hand. Based on a given application/environment at hand, the value of the retry threshold of block 236b (and/or the second threshold of block 232b) may be selected, accordingly, to facilitate an appropriate trade-off.

In block 244b, the testing component 226a may perform additional testing/verification on the unlabeled traffic 218a to enhance the confidence/score of block 224b (or the confidence/score generated as part of a prior execution of block 236b with respect to the unlabeled traffic 218a obtained in block 212b). For example, as part of block 244b the unlabeled traffic 218a may be subject to additional algorithms, surveys/polling of different entities or computing devices, etc., in an effort to gain confidence as to whether the prediction of block 220b is indeed accurate. As part of block 244b, the retry counter may be incremented.

From block 244b, flow may proceed to block 228b. As part of that flow from block 244b to block 228b, the enhanced confidence obtained as part of block 244b may be assessed relative to the first threshold. Stated slightly differently, following the first execution of blocks 228b and 232b with respect to the unlabeled traffic 218a (of block 212b), subsequent executions of the block 228b and the block 232b may utilize the enhanced confidence obtained as part of block 244b (in lieu of the confidence generated in block 224b).

In block 240b, the method 200b may end/terminate with respect to the unlabeled traffic 218a of block 212b. As described above, aspects of the block 240b may serve to exclude the unlabeled traffic 218a from influencing/impacting (a refinement of) the model 214a.

While for purposes of simplicity of explanation, the respective processes are shown and described as a series of blocks in FIG. 2B, it is to be understood and appreciated that the claimed subject matter is not limited by the order of the blocks, as some blocks may occur in different orders and/or concurrently with other blocks from what is depicted and described herein. Moreover, not all illustrated blocks may be required to implement the methods described herein.

Aspects of the method 200b may be executed iteratively or repeatedly. For example, the method 200b may be executed each time a new or additional traffic item is obtained.

As described herein, traffic that traverses a network may take one or more forms. For example, a traffic item may include control data, a payload/payload data, etc. A traffic item may pertain/relate to one or more applications, programs, systems, devices, components, etc. A traffic item may be encrypted or unencrypted in traversing at least part of a network infrastructure from a source to a destination.

As described herein, a model may be generated in a first instance in accordance with known/labeled categories/classes of traffic. The model may subsequently be refined/modified/updated, in accordance with a machine-learning based approach, in view of additional/new traffic that is obtained. In some embodiments, the model may be used to generate a prediction regarding a category/class associated with an unlabeled traffic item, and a confidence associated with the prediction. If the confidence is sufficiently high, the prediction may be used to drive an update to the model as warranted.

In accordance with aspects of this disclosure, a categorization/classification assigned to unlabeled traffic may serve as a parameter/input to a decision-making process regarding a utilization/allocation of one or more resources. For example, a network operator/service provider may select a first resource with a first parameter (e.g., a first transmission bandwidth) for a first category/class of traffic (e.g., video traffic) and may select a second resource with a second parameter (e.g., a second transmission bandwidth) for a second category/class of traffic (e.g., non-video traffic). More generally, the assignment of a category/class to unlabeled traffic may facilitate efficiency and scalability with respect to the operation and maintenance of one or more networks.

An assignment/allocation of a resource may include a selection of an operating parameter for the resource. A category/classification of traffic may serve as one of a plurality of factors/considerations in terms of an assignment/allocation of a resource. For example, other factors/considerations may include a volume/amount of the traffic, forecasted traffic, an identification of a date or time, an identification of a type (e.g., make or model) of device that is generating/transmitting and/or receiving traffic, a subscription plan or license agreement/arrangement in terms of, e.g., a quality of service parameter, etc.

Referring now to FIG. 3, a block diagram 300 is shown illustrating an example, non-limiting embodiment of a virtualized communication network in accordance with various aspects described herein. In particular a virtualized communication network is presented that can be used to implement some or all of the subsystems and functions of communication network 100, the subsystems and functions of system 200a, and method 200b presented in FIGS. 1, 2A, and 2B. For example, virtualized communication network 300 can facilitate in whole or in part obtaining a first plurality of traffic items, wherein each traffic item of the first plurality of traffic items is labeled with a first label as video traffic, obtaining a second plurality of traffic items, wherein each traffic item of the second plurality of traffic items is labeled with a second label as non-video traffic, generating a model in accordance with the first plurality of traffic items, the first label, the second plurality of traffic items, and the second label, obtaining a first unlabeled traffic item, wherein the first unlabeled traffic item is encrypted, applying the model to the first unlabeled traffic item to generate a first prediction regarding whether the first unlabeled traffic item is a video traffic item or a non-video traffic item, and generating a first score that is representative of a first confidence of the first prediction. Communication network 300 can facilitate in whole or in part obtaining a first unlabeled traffic item, wherein the first unlabeled traffic item is encrypted, applying a model to the first unlabeled traffic item to generate a first prediction regarding whether the first unlabeled traffic item is a video traffic item or a non-video traffic item, generating a first score that is representative of a first confidence of the first prediction, and outputting, via a user interface, an indication of the first prediction and the first score. Communication network 300 can facilitate in whole or in part applying a model to a first unlabeled traffic item to generate a classification of the first unlabeled traffic item as a first class of traffic items or a second class of traffic items, generating a first score that is representative of a first confidence of the classification, determining that the first score is greater than a first threshold, and responsive to determining that the first score is greater than the first threshold, refining the model in accordance with at least the classification, resulting in a modified model

In particular, a cloud networking architecture is shown that leverages cloud technologies and supports rapid innovation and scalability via a transport layer 350, a virtualized network function cloud 325 and/or one or more cloud computing environments 375. In various embodiments, this cloud networking architecture is an open architecture that leverages application programming interfaces (APIs); reduces complexity from services and operations; supports more nimble business models; and rapidly and seamlessly scales to meet evolving customer requirements including traffic growth, diversity of traffic types, and diversity of performance and reliability expectations.

In contrast to traditional network elements—which are typically integrated to perform a single function, the virtualized communication network employs virtual network elements (VNEs) 330, 332, 334, etc. that perform some or all of the functions of network elements 150, 152, 154, 156, etc. For example, the network architecture can provide a substrate of networking capability, often called Network Function Virtualization Infrastructure (NFVI) or simply infrastructure that is capable of being directed with software and Software Defined Networking (SDN) protocols to perform a broad variety of network functions and services. This infrastructure can include several types of substrates. The most typical type of substrate being servers that support Network Function Virtualization (NFV), followed by packet forwarding capabilities based on generic computing resources, with specialized network technologies brought to bear when general purpose processors or general purpose integrated circuit devices offered by merchants (referred to herein as merchant silicon) are not appropriate. In this case, communication services can be implemented as cloud-centric workloads.

As an example, a traditional network element 150 (shown in FIG. 1), such as an edge router can be implemented via a VNE 330 composed of NFV software modules, merchant silicon, and associated controllers. The software can be written so that increasing workload consumes incremental resources from a common resource pool, and moreover so that it's elastic: so the resources are only consumed when needed. In a similar fashion, other network elements such as other routers, switches, edge caches, and middle-boxes are instantiated from the common resource pool. Such sharing of infrastructure across a broad set of uses makes planning and growing infrastructure easier to manage.

In an embodiment, the transport layer 350 includes fiber, cable, wired and/or wireless transport elements, network elements and interfaces to provide broadband access 110, wireless access 120, voice access 130, media access 140 and/or access to content sources 175 for distribution of content to any or all of the access technologies. In particular, in some cases a network element needs to be positioned at a specific place, and this allows for less sharing of common infrastructure. Other times, the network elements have specific physical layer adapters that cannot be abstracted or virtualized, and might require special DSP code and analog front-ends (AFEs) that do not lend themselves to implementation as VNEs 330, 332 or 334. These network elements can be included in transport layer 350.

The virtualized network function cloud 325 interfaces with the transport layer 350 to provide the VNEs 330, 332, 334, etc. to provide specific NFVs. In particular, the virtualized network function cloud 325 leverages cloud operations, applications, and architectures to support networking workloads. The virtualized network elements 330, 332 and 334 can employ network function software that provides either a one-for-one mapping of traditional network element function or alternately some combination of network functions designed for cloud computing. For example, VNEs 330, 332 and 334 can include route reflectors, domain name system (DNS) servers, and dynamic host configuration protocol (DHCP) servers, system architecture evolution (SAE) and/or mobility management entity (MME) gateways, broadband network gateways, IP edge routers for IP-VPN, Ethernet and other services, load balancers, distributers and other network elements. Because these elements don't typically need to forward large amounts of traffic, their workload can be distributed across a number of servers—each of which adds a portion of the capability, and overall which creates an elastic function with higher availability than its former monolithic version. These virtual network elements 330, 332, 334, etc. can be instantiated and managed using an orchestration approach similar to those used in cloud compute services.

The cloud computing environments 375 can interface with the virtualized network function cloud 325 via APIs that expose functional capabilities of the VNEs 330, 332, 334, etc. to provide the flexible and expanded capabilities to the virtualized network function cloud 325. In particular, network workloads may have applications distributed across the virtualized network function cloud 325 and cloud computing environment 375 and in the commercial cloud, or might simply orchestrate workloads supported entirely in NFV infrastructure from these third party locations.

The HDD 414, magnetic FDD 416 and optical disk drive 420 can be connected to the system bus 408 by a hard disk drive interface 424, a magnetic disk drive interface 426 and an optical drive interface 428, respectively. The hard disk drive interface 424 for external drive implementations comprises at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein.

The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 402, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to a hard disk drive (HDD), a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, can also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein.

A number of program modules can be stored in the drives and RAM 412, comprising an operating system 430, one or more application programs 432, other program modules 434 and program data 436.

The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems.

A user can enter commands and information into the computer 402 through one or more wired/wireless input devices, e.g., a keyboard 438 and a pointing device, such as a mouse 440. Other input devices (not shown) can comprise a microphone, an infrared (IR) remote control, a joystick, a game pad, a stylus pen, touch screen or the like. These and other input devices are often connected to the processing unit 404 through an input device interface 442 that can be coupled to the system bus 408, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a universal serial bus (USB) port, an IR interface, etc.

A monitor 444 or other type of display device can be also connected to the system bus 408 via an interface, such as a video adapter 446. It will also be appreciated that in alternative embodiments, a monitor 444 can also be any display device (e.g., another computer having a display, a smart phone, a tablet computer, etc.) for receiving display information associated with computer 402 via any communication means, including via the Internet and cloud-based networks. In addition to the monitor 444, a computer typically comprises other peripheral output devices (not shown), such as speakers, printers, etc.

The computer 402 can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 448. The remote computer(s) 448 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically comprises many or all of the elements described relative to the computer 402, although, for purposes of brevity, only a remote memory/storage device 450 is illustrated. The logical connections depicted comprise wired/wireless connectivity to a local area network (LAN) 452 and/or larger networks, e.g., a wide area network (WAN) 454. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet.

When used in a LAN networking environment, the computer 402 can be connected to the LAN 452 through a wired and/or wireless communication network interface or adapter 456. The adapter 456 can facilitate wired or wireless communication to the LAN 452, which can also comprise a wireless AP disposed thereon for communicating with the adapter 456.

This can comprise Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

Wi-Fi can allow connection to the Internet from a couch at home, a bed in a hotel room or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, n, ac, ag, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which can use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands for example or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.

Turning now to FIG. 5, an embodiment 500 of a mobile network platform 510 is shown that is an example of network elements 150, 152, 154, 156, and/or VNEs 330, 332, 334, etc. For example, platform 510 can facilitate in whole or in part obtaining a first plurality of traffic items, wherein each traffic item of the first plurality of traffic items is labeled with a first label as video traffic, obtaining a second plurality of traffic items, wherein each traffic item of the second plurality of traffic items is labeled with a second label as non-video traffic, generating a model in accordance with the first plurality of traffic items, the first label, the second plurality of traffic items, and the second label, obtaining a first unlabeled traffic item, wherein the first unlabeled traffic item is encrypted, applying the model to the first unlabeled traffic item to generate a first prediction regarding whether the first unlabeled traffic item is a video traffic item or a non-video traffic item, and generating a first score that is representative of a first confidence of the first prediction. Platform 510 can facilitate in whole or in part obtaining a first unlabeled traffic item, wherein the first unlabeled traffic item is encrypted, applying a model to the first unlabeled traffic item to generate a first prediction regarding whether the first unlabeled traffic item is a video traffic item or a non-video traffic item, generating a first score that is representative of a first confidence of the first prediction, and outputting, via a user interface, an indication of the first prediction and the first score. Platform 510 can facilitate in whole or in part applying a model to a first unlabeled traffic item to generate a classification of the first unlabeled traffic item as a first class of traffic items or a second class of traffic items, generating a first score that is representative of a first confidence of the classification, determining that the first score is greater than a first threshold, and responsive to determining that the first score is greater than the first threshold, refining the model in accordance with at least the classification, resulting in a modified model.

In one or more embodiments, the mobile network platform 510 can generate and receive signals transmitted and received by base stations or access points such as base station or access point 122. Generally, mobile network platform 510 can comprise components, e.g., nodes, gateways, interfaces, servers, or disparate platforms, that facilitate both packet-switched (PS) (e.g., internet protocol (IP), frame relay, asynchronous transfer mode (ATM)) and circuit-switched (CS) traffic (e.g., voice and data), as well as control generation for networked wireless telecommunication. As a non-limiting example, mobile network platform 510 can be included in telecommunications carrier networks, and can be considered carrier-side components as discussed elsewhere herein. Mobile network platform 510 comprises CS gateway node(s) 512 which can interface CS traffic received from legacy networks like telephony network(s) 540 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a signaling system #7 (SS7) network 560. CS gateway node(s) 512 can authorize and authenticate traffic (e.g., voice) arising from such networks. Additionally, CS gateway node(s) 512 can access mobility, or roaming, data generated through SS7 network 560; for instance, mobility data stored in a visited location register (VLR), which can reside in memory 530. Moreover, CS gateway node(s) 512 interfaces CS-based traffic and signaling and PS gateway node(s) 518. As an example, in a 3GPP UMTS network, CS gateway node(s) 512 can be realized at least in part in gateway GPRS support node(s) (GGSN). It should be appreciated that functionality and specific operation of CS gateway node(s) 512, PS gateway node(s) 518, and serving node(s) 516, is provided and dictated by radio technology(ies) utilized by mobile network platform 510 for telecommunication over a radio access network 520 with other devices, such as a radiotelephone 575.

In addition to receiving and processing CS-switched traffic and signaling, PS gateway node(s) 518 can authorize and authenticate PS-based data sessions with served mobile devices. Data sessions can comprise traffic, or content(s), exchanged with networks external to the mobile network platform 510, like wide area network(s) (WANs) 550, enterprise network(s) 570, and service network(s) 580, which can be embodied in local area network(s) (LANs), can also be interfaced with mobile network platform 510 through PS gateway node(s) 518. It is to be noted that WANs 550 and enterprise network(s) 570 can embody, at least in part, a service network(s) like IP multimedia subsystem (IMS). Based on radio technology layer(s) available in technology resource(s) or radio access network 520, PS gateway node(s) 518 can generate packet data protocol contexts when a data session is established; other data structures that facilitate routing of packetized data also can be generated. To that end, in an aspect, PS gateway node(s) 518 can comprise a tunnel interface (e.g., tunnel termination gateway (TTG) in 3GPP UMTS network(s) (not shown)) which can facilitate packetized communication with disparate wireless network(s), such as Wi-Fi networks.

In embodiment 500, mobile network platform 510 also comprises serving node(s) 516 that, based upon available radio technology layer(s) within technology resource(s) in the radio access network 520, convey the various packetized flows of data streams received through PS gateway node(s) 518. It is to be noted that for technology resource(s) that rely primarily on CS communication, server node(s) can deliver traffic without reliance on PS gateway node(s) 518; for example, server node(s) can embody at least in part a mobile switching center. As an example, in a 3GPP UMTS network, serving node(s) 516 can be embodied in serving GPRS support node(s) (SGSN).

For radio technologies that exploit packetized communication, server(s) 514 in mobile network platform 510 can execute numerous applications that can generate multiple disparate packetized data streams or flows, and manage (e.g., schedule, queue, format . . . ) such flows. Such application(s) can comprise add-on features to standard services (for example, provisioning, billing, customer support . . . ) provided by mobile network platform 510. Data streams (e.g., content(s) that are part of a voice call or data session) can be conveyed to PS gateway node(s) 518 for authorization/authentication and initiation of a data session, and to serving node(s) 516 for communication thereafter. In addition to application server, server(s) 514 can comprise utility server(s), a utility server can comprise a provisioning server, an operations and maintenance server, a security server that can implement at least in part a certificate authority and firewalls as well as other security mechanisms, and the like. In an aspect, security server(s) secure communication served through mobile network platform 510 to ensure network's operation and data integrity in addition to authorization and authentication procedures that CS gateway node(s) 512 and PS gateway node(s) 518 can enact. Moreover, provisioning server(s) can provision services from external network(s) like networks operated by a disparate service provider; for instance, WAN 550 or Global Positioning System (GPS) network(s) (not shown). Provisioning server(s) can also provision coverage through networks associated to mobile network platform 510 (e.g., deployed and operated by the same service provider), such as the distributed antennas networks shown in FIG. 1(s) that enhance wireless service coverage by providing more network coverage.

It is to be noted that server(s) 514 can comprise one or more processors configured to confer at least in part the functionality of mobile network platform 510. To that end, the one or more processor can execute code instructions stored in memory 530, for example. It is should be appreciated that server(s) 514 can comprise a content manager, which operates in substantially the same manner as described hereinbefore.

In example embodiment 500, memory 530 can store information related to operation of mobile network platform 510. Other operational information can comprise provisioning information of mobile devices served through mobile network platform 510, subscriber databases; application intelligence, pricing schemes, e.g., promotional rates, flat-rate programs, couponing campaigns; technical specification(s) consistent with telecommunication protocols for operation of disparate radio, or wireless, technology layers; and so forth. Memory 530 can also store information from at least one of telephony network(s) 540, WAN 550, SS7 network 560, or enterprise network(s) 570. In an aspect, memory 530 can be, for example, accessed as part of a data store component or as a remotely connected memory store.

In order to provide a context for the various aspects of the disclosed subject matter, FIG. 5, and the following discussion, are intended to provide a brief, general description of a suitable environment in which the various aspects of the disclosed subject matter can be implemented. While the subject matter has been described above in the general context of computer-executable instructions of a computer program that runs on a computer and/or computers, those skilled in the art will recognize that the disclosed subject matter also can be implemented in combination with other program modules. Generally, program modules comprise routines, programs, components, data structures, etc. that perform particular tasks and/or implement particular abstract data types.

Computing device 600 can facilitate in whole or in part obtaining a first unlabeled traffic item, wherein the first unlabeled traffic item is encrypted, applying a model to the first unlabeled traffic item to generate a first prediction regarding whether the first unlabeled traffic item is a video traffic item or a non-video traffic item, generating a first score that is representative of a first confidence of the first prediction, and outputting, via a user interface, an indication of the first prediction and the first score. Computing device 600 can facilitate in whole or in part applying a model to a first unlabeled traffic item to generate a classification of the first unlabeled traffic item as a first class of traffic items or a second class of traffic items, generating a first score that is representative of a first confidence of the classification, determining that the first score is greater than a first threshold, and responsive to determining that the first score is greater than the first threshold, refining the model in accordance with at least the classification, resulting in a modified model.

The display 610 can use touch screen technology to also serve as a user interface for detecting user input. As a touch screen display, the communication device 600 can be adapted to present a user interface having graphical user interface (GUI) elements that can be selected by a user with a touch of a finger. The display 610 can be equipped with capacitive, resistive or other forms of sensing technology to detect how much surface area of a user's finger has been placed on a portion of the touch screen display. This sensing information can be used to control the manipulation of the GUI elements or other functions of the user interface.

The UI 604 can further include an image sensor 613 such as a charged coupled device (CCD) camera for capturing still or moving images.

The power supply 614 can utilize common power management technologies such as replaceable and rechargeable batteries, supply regulation technologies, and/or charging system technologies for supplying energy to the components of the communication device 600 to facilitate long-range or short-range portable communications. Alternatively, or in combination, the charging system can utilize external power sources such as DC power supplied over a physical interface such as a USB port or other suitable tethering technologies.

The location receiver 616 can utilize location technology such as a global positioning system (GPS) receiver capable of assisted GPS for identifying a location of the communication device 600 based on signals generated by a constellation of GPS satellites, which can be used for facilitating location services such as navigation. The motion sensor 618 can utilize motion sensing technology such as an accelerometer, a gyroscope, or other suitable motion sensing technology to detect motion of the communication device 600 in three-dimensional space. The orientation sensor 620 can utilize orientation sensing technology such as a magnetometer to detect the orientation of the communication device 600 (north, south, west, and east, as well as combined orientations in degrees, minutes, or other suitable orientation metrics).

The communication device 600 can use the transceiver 602 to also determine a proximity to a cellular, WiFi, Bluetooth®, or other wireless access points by sensing techniques such as utilizing a received signal strength indicator (RSSI) and/or signal time of arrival (TOA) or time of flight (TOF) measurements. The controller 606 can utilize computing technologies such as a microprocessor, a digital signal processor (DSP), programmable gate arrays, application specific integrated circuits, and/or a video processor with associated storage memory such as Flash, ROM, RAM, SRAM, DRAM or other storage technologies for executing computer instructions, controlling, and processing data supplied by the aforementioned components of the communication device 600.

SIM or UICC cards can be used for identifying subscriber services, executing programs, storing subscriber data, and so on.

The terms “first,” “second,” “third,” and so forth, as used in the claims, unless otherwise clear by context, is for clarity only and doesn't otherwise indicate or imply any order in time. For instance, “a first determination,” “a second determination,” and “a third determination,” does not indicate or imply that the first determination is to be made before the second determination, or vice versa, etc.

In the subject specification, terms such as “store,” “storage,” “data store,” data storage,” “database,” and substantially any other information storage component relevant to operation and functionality of a component, refer to “memory components,” or entities embodied in a “memory” or components comprising the memory. It will be appreciated that the memory components described herein can be either volatile memory or nonvolatile memory, or can comprise both volatile and nonvolatile memory, by way of illustration, and not limitation, volatile memory, non-volatile memory, disk storage, and memory storage. Further, nonvolatile memory can be included in read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), or flash memory. Volatile memory can comprise random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM). Additionally, the disclosed memory components of systems or methods herein are intended to comprise, without being limited to comprising, these and any other suitable types of memory.

Moreover, it will be noted that the disclosed subject matter can be practiced with other computer system configurations, comprising single-processor or multiprocessor computer systems, mini-computing devices, mainframe computers, as well as personal computers, hand-held computing devices (e.g., PDA, phone, smartphone, watch, tablet computers, netbook computers, etc.), microprocessor-based or programmable consumer or industrial electronics, and the like. The illustrated aspects can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network; however, some if not all aspects of the subject disclosure can be practiced on stand-alone computers. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.

In one or more embodiments, information regarding use of services can be generated including services being accessed, media consumption history, user preferences, and so forth. This information can be obtained by various methods including user input, detecting types of communications (e.g., video content vs. audio content), analysis of content streams, sampling, and so forth. The generating, obtaining and/or monitoring of this information can be responsive to an authorization provided by the user. In one or more embodiments, an analysis of data can be subject to authorization from user(s) associated with the data, such as an opt-in, an opt-out, acknowledgement requirements, notifications, selective authorization based on types of data, and so forth.

Some of the embodiments described herein can also employ artificial intelligence (AI) to facilitate automating one or more features described herein. The embodiments (e.g., in connection with automatically identifying acquired cell sites that provide a maximum value/benefit after addition to an existing communication network) can employ various AI-based schemes for carrying out various embodiments thereof. Moreover, the classifier can be employed to determine a ranking or priority of each cell site of the acquired network. A classifier is a function that maps an input attribute vector, x=(x1, x2, x3, x4, . . . , xn), to a confidence that the input belongs to a class, that is, f(x)=confidence (class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to determine or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which the hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches comprise, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.

As will be readily appreciated, one or more of the embodiments can employ classifiers that are explicitly trained (e.g., via a generic training data) as well as implicitly trained (e.g., via observing UE behavior, operator preferences, historical information, receiving extrinsic information). For example, SVMs can be configured via a learning or training phase within a classifier constructor and feature selection module. Thus, the classifier(s) can be used to automatically learn and perform a number of functions, including but not limited to determining according to predetermined criteria which of the acquired cell sites will benefit a maximum number of subscribers and/or which of the acquired cell sites will add minimum value to the existing communication network coverage, etc.

As used in some contexts in this application, in some embodiments, the terms “component,” “system” and the like are intended to refer to, or comprise, a computer-related entity or an entity related to an operational apparatus with one or more specific functionalities, wherein the entity can be either hardware, a combination of hardware and software, software, or software in execution.
