Abstract: In some implementations, a method includes analyzing an amount of data communicated by a set of network interfaces. The data communicated by the set of network interfaces is processed by a set of functional units and a set of queues includes the data communicated by the set of network interfaces. The method also includes activating a first functional unit of the set of functional units when a first size of a first queue of the set of queues is above a first threshold. The method further includes deactivating the first functional unit of the set of functional units when the first size of the first queue of the set of queues is below a second threshold. The method further includes causing the data to be forward to one or more active functional units via a data interconnect coupled to the set of network interfaces and the set of functional units.

Abstract: In one embodiment, a network assurance service that monitors a network detects a pattern of network measurements from the network that are associated with a particular network problem. The network assurance service tracks characteristics of the detected pattern over time. The network assurance service uses the tracked characteristics of the detected pattern over time as input to a machine learning-based pattern analyzer. The pattern analyzer is configured to determine whether the detected pattern is a perpetual or transient pattern in the network, and the pattern analyzer is further configured to detect anomalies in the characteristics of the pattern. The network assurance service initiates a change to the network based on an output of the machine learning-based pattern analyzer.

Abstract: Presented herein are techniques in which one or more network devices can use information provided by a special purpose network connected device to retrieve a usage profile (i.e., configuration file) associated with the special purpose network connected device. The retrieved usage profile, which includes/describes preselected (predetermined) usage descriptions associated with the special purpose network connected device, can then be used to configure one or more network devices. For example, the predetermined usage descriptions associated with the special purpose network connected device can be instantiated and enforced at a network device or the predetermined usage descriptions can be used for auditing the special purpose network connected device (e.g., monitoring of traffic within the network).

Abstract: The embodiments herein describe an optical transmitter that integrates a SCOWA into a photonic chip that includes a modulator. The embodiments herein place the SCOWA between the laser and the modulator. To accommodate the large mode size of the waveguide in the SCOWA, the photonic chip includes a pair of spot size converters coupled to the input and output of the SCOWA. Rather than amplifying a modulated signal as is typical with an inline amplifier, the SCOWA amplifies a continuous wave (CW) optical signal generated by the laser which introduces less noise and improves the OSNR of the transmitter.

Abstract: An aspect of the present disclosure aims to reduce problems associated with data acquisition of a rule set. Systems and methods enabling a semantic reasoner to stage acquisition of data objects necessary to bring each of the rules stored in the knowledge base to a conclusion are disclosed. To that end, a dependency chain is constructed, identifying whether and how each rule depends on other rules. Based on the dependency chain, the rules are assigned to difference epochs and reasoning engine is configured to perform machine reasoning over rules of each epoch sequentially. Moreover, when processing rules of each epoch, data objects referenced by the rules assigned to a currently processed epoch are acquired according to a certain order established based on criteria such as e.g. cost of acquisition of data objects. Such an approach provides automatic determination and just-in-time acquisition of data objects required for semantic reasoning.

Abstract: A server is configured to host a web-based collaboration room through which user devices of member users are able to communicate. Each of the member users is assigned a distinct communication identifier. The server generates for display at each of the user devices a selectable start option associated with the communication identifier assigned to the user of the user device. The server receives from a first user device among the user devices a selection of the start option and that includes the communication identifier of a first user among the users. In response, the server initiates a communication session, connects the first user device to the communication session, links the received communication identifier to the communication session, and generates for display at each of the user devices a respective selectable join option associated with the linked communication identifier and by which the communication session is accessible.

Abstract: In one embodiment, a server determines a trigger to diagnose a software as a service (SaaS) pipeline for a SaaS client, and sends a notification to a plurality of SaaS nodes in the pipeline that the client is in a diagnostic mode, the notification causing the plurality of SaaS nodes to establish taps to collect diagnostic information for the client. The server may then send client-specific diagnostic messages into the SaaS pipeline for the client, the client-specific diagnostic messages causing the taps on the plurality of SaaS nodes to collect client-specific diagnostic information and send the client-specific diagnostic information to the server. The server then receives the client-specific diagnostic information from the plurality of SaaS nodes, and creates a client-specific diagnostic report based on the client-specific diagnostic information.

Abstract: One embodiment provides a system that facilitates schematized access control in a content centric network. During operation, the system generates, by a content producing device, a secret key for a user based on a schema, wherein the schema is a regular expression which corresponds to one or more names and allows a user access to content associated with the names, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. The system receives an interest with a name that corresponds to the schema. The system encrypts a payload of a responsive content object based on the interest name. The system transmits the responsive content object with the encrypted payload to the user, which allows the user to decrypt the encrypted payload with the secret key.
