Abstract: A network device may receive encoded provisioning information from a source of provisioning information, such as a bootstrap server, as part of a provisioning operation. An analysis tool on a client device or on the network device may be configured to obtain the encoded provisioning information, parse the encoded provisioning information to obtain one or more decoded portions of the provisioning information, and output information resulting from the parsing operation, thereby providing insight into device provisioning information often encoded in a complex manner.

Abstract: Systems and methods for identifying and evicting idle sessions include training a machine learning model as a session classifying model to learn rules for classifying active sessions between clients and the cloud-based service. The session classifying model is trained to receive a plurality of parameters pertaining to the document associated with an active session as input and to apply the rules to the plurality of parameters to determine a classification for the active session and to provide an output indicative of the classification for the active session. The session classifying model is then utilized in the cloud-based service to classify the active sessions. The active sessions classified as idle sessions may then be evicted from the cloud-based service.

Abstract: A comprehensive approach for segmenting encrypted streams of media content into individual sessions is provided herein. Particularly, a network node identifies a connection to a known content delivery related domain and receives the data packets comprising the encrypted streams over the connection. The data packets comprise a pattern of one or more features indicating a media content start event for the media content being provided to a subscriber via the connection. The subsequent network activity is then monitored in a pre-determined time frame and an associated pattern analyzed. A media content start event may then be detected based on the analysis of the pattern.

Abstract: Methods and systems for managing requests in a distributed computing system are provided. A plurality of requests are received by one or more of the plurality of computing nodes in the distributed computing system. A respective timestamp is assigned to each of the plurality of requests.

Next, the creation of an instance process may be performed on an entity operating outside the enterprise network and the application may be operated via the instance process and otherwise terminated in the enterprise network to alleviate resources.

Abstract: The technology disclosed herein enables redistribution of connections between service instances by determining a subset of the connections and terminating the subset. In a particular example, a method includes determining connection information about connections established with service instances operating in an active-active configuration. The connection information identifies directions of connection initiation for the connections and identifies peers for the connections. Based on the connection information, the method includes determining a subset of the connections for reestablishment on a per-peer basis using direction-dependent criteria and terminating the subset of the connections.

Abstract: There is provided a method for handling a service request. The method is performed by a service communication proxy (SCP) node. The SCP node is configured to operate as an SCP between a first network function (NF) node of a service consumer and a second NF node of a service producer in the network. The method is performed in response to receiving, from the second NF node, a first response to a first request transmitted towards the second NF node via the SCP node. The first request is for the second NF node to provide a first service requested by the first NF node. Transmission of a second response is initiated towards the first NF node. The second response includes binding information irrespective of whether the binding information is present in the first response.

Abstract: In one embodiment, a device obtains quality of experience metrics for an online application whose traffic traverses a particular interface of a router located at a first site in a network. The device identifies a correlation between throughput of the particular interface and the quality of experience metrics for the online application. The device makes a determination that the correlation is a root cause of degradation of the quality of experience metrics for the online application at least in part by determining whether throughput of an interface of a remote router located at a second site in the network is correlated with the quality of experience metrics. The device configures, based on the determination, a priority queue associated with the particular interface for use by traffic of the online application.

The control unit operates such that, when having received, from a user, a request regarding an application that chains one or more application functions (AFs) to act on a packet flowing in the network, the control unit acquires information regarding the application from a second zone being a management domain other than the first zone, and then calculates a deployment destination of the AFs in the network including the first zone and the second zone based on the information.

Abstract: A network disruption detection engine gathers and stores network routing path update messages that routinely modify routing tables used by internet routers for transporting message traffic between a source and a destination. Routing path messages continually maintain a network transport infrastructure both for intranets used for particular entities such as corporations, and internet traffic between arbitrary source and destination nodes. Major disruptions or outages typically result in an increase in routing path messages, typically focused on a particular set, region or network entity where the disruption occurred, as other routing entities seek to avoid the troubled region. Analysis of this sudden activity of routing messages and extracting message content about the network region they seek to avoid allows identification and queries of a widespread network outage.

Abstract: Timestamp circuitry of a network device modifies a packet by embedding a future timestamp in the packet to generate a timestamped packet. The future timestamp corresponds to a transmit time that occurs after the timestamp circuitry embeds the future timestamp in the packet. The timing information is added to the packet and the packet is then transferred to transmitter circuitry of the network device via a communication link, internal to the network device, that operates according to a media independent communication interface. Time gating circuitry of the transmitter circuitry i) holds the timestamped packet from proceeding to a network link coupled to the network device prior to a current time reaching the transmit time, and ii) releases the timestamped packet for transmission via the network link in response to the current time reaching the transmit time.
