Abstract: In one embodiment, a physical (PHY) layer (lower protocol stack layer) of a device may add a timestamp to a received frame, and pass the frame and timestamp up the protocol stack toward a synchronization (sync) recognition layer (upper protocol stack layer). The sync recognition layer determines whether the frame relates to synchronization, and if so, places the timestamp into a data structure along with a frame association for recovery by followup processing. Conversely, in another embodiment, the sync recognition layer may add to a frame for transmission a frame ID having an indication of whether to timestamp the frame and may pass the frame and frame ID down the protocol stack toward the PHY layer. The PHY layer determines whether the frame ID indicates that the frame is to be timestamped, and if so, places a timestamp corresponding to frame transmission into a data structure with the frame ID.

Abstract: Systems, methods, and computer-readable storage media for detecting network loops. A system can identify, for each virtual tunnel endpoint (VTEP) from multiple VTEPs in a network, respective media access control address data including the respective local interface media access control addresses of the respective VTEP and respective media access control addresses learned by the respective VTEP. The system can determine whether the VTEPs are running spanning tree protocol (STP), and whether a media access control address learned by a first VTEP matches a respective local interface media access control address of a second VTEP. The system can detect a loop when the media access control address learned by the first VTEP matches the respective local interface media access control address of the second VTEP. The system can also detect a loop when the VTEPs are running STP and the first and second VTEPs see the same STP root bridge.

Abstract: A device receives signals over a communication medium and uses a low density parity check decoder to decode data in the signals. A number of unsatisfied parity checks are counted prior to a first decoding iteration of the low density parity check decoder on a basis of log likelihood ratios computed from the signals. An operational characteristic of the low density parity check decoder is computed based on an accumulated number of unsatisfied parity checks.

Abstract: A method is provided in one example embodiment and includes receiving at a network element a packet associated with a flow and determining whether a flow cache of the network element includes an entry for the flow indicating a classification for the flow. The method further includes, if the network element flow cache does not include an entry for the flow, punting the packet over a default path to a classifying service function, in which the classifying service function classifies the flow and determines a control plane service function for handling the flow, and receiving from the classifying service function a service path identifier (“SPI”) of a service path leading to the determined control plane service function. The flow is subsequently offloaded from the classifying service function to the network element.

Abstract: In one embodiment, a device in a network receives traffic data associated with a particular communication channel between two or more nodes in the network. The device generates a mean map by employing kernel embedding of distributions to the traffic data.

The device generates a traffic classifier using the representation of the communication channel. The device uses machine learning to jointly identify the set of lattice points and one or more parameters of the traffic classifier. The device causes the traffic classifier to analyze network traffic sent via the communication channel.

Abstract: In one embodiment, a caching resolver receives a name server query from an end device for an Internet Protocol (IP) address for a hostname, and determines whether the hostname requested is in an access control list (ACL). In response to the hostname being in the ACL, the caching resolver examines a received response to the name server query for the hostname, wherein the received response contains a particular IP address for the hostname, and adds the particular IP address for the hostname to the ACL. In one embodiment, the ACL is local to the caching resolver, while in another embodiment, adding the particular IP address for the hostname to the ACL comprises sending a message to a remote ACL-maintaining device that maintains the ACL.
