  • Patent number: 11784928
    Abstract: Presented herein are methods and systems that facilitate data plane signaling of a packet as a candidate for capture at various network nodes within an IPv6 network. The signaling occurs in-band, via the data plane—that is, a capture or interrogation signal is embedded within the respective packet (e.g., in the packet header) that carries a user traffic. The signaling is inserted, preferably when the packet is classified, e.g., at the ingress node of the network, to which subsequent network nodes with the IPv6 network are signaled to capture or further inspect the packet for capture.
    Type: Grant

  • Patent number: 10862910
    Abstract: In one embodiment, a server may receive both layer-2 topology information and layer-2 telemetry information from a plurality of layer-2 switches. The server may then apply behavioral learning to both the layer-2 topology information and the layer-2 telemetry information to detect layer-2 patterns that are indicative of one or more problematic layer-2 behaviors. As such, based on the behavioral learning, the server then creates predictive rules to be applied within layer-2 networks to predict the one or more problematic layer-2 behaviors. The predictive rules may then be used within a particular layer-2 network to cause i) prediction of one or more particular problematic layer-2 behaviors within the particular layer-2 network based on data from a plurality of switches within the particular layer-2 network, and ii) mitigation against the predicted one or more particular problematic layer-2 behaviors within the particular layer-2 network.

  • Patent number: 10778572
    Abstract: Presented herein are segment-routing methods and systems that facilitate data plane signaling of a packet as a candidate for capture at various network nodes within a segment routing (SR) network. The signaling occurs in-band, via the data plane—that is, a capture or interrogation signal is embedded within the respective packet that carries a user traffic. The signaling is inserted, preferably when the packet is classified, e.g., at the ingress node of the network, to which subsequent network nodes with the SR network are signaled to capture or further inspect the packet for capture.

  • Patent number: 10003660
    Abstract: Presented herein are service-function chaining techniques that enable data plane signaling of a packet as a candidate for capture at various network nodes along a service function path of a service function chain. That is, a capture signal is embedded within the respective packet that carries a user traffic. The signaling occurs in-band, via the data plane, such that classification of the packet for capture beneficially occurs, at the ingress node of the network, once to which subsequent network nodes along a service function path are signaled to capture or further inspect the packet for capture. Service function chaining treats service functions as resources with associated attributes available for scheduled consumption to which selective traffic are steered according to a policy construct to the requisite network-service resources.
