Abstract: Systems, methods, and computer-readable media for offloading session management processing into a forwarding plane. In some examples, a subscriber is coupled to a network endpoint through a session manager during a network session of the subscriber in a network environment. A session manager offloading system of the session manager can be maintained in a vector packet processing system in a forwarding plane of the network environment. The session manager offloading system can be configured to offload processing from the session manager into the forwarding plane. Further, at least a portion of subscriber traffic in a stream between the subscriber and the network endpoint through the session manager can be intercepted. Subsequently, the at least the portion of the subscribed traffic that is intercepted can be processed at the session manager offloading system as part of offloading the processing from the session manager into the forwarding plane.

Abstract: Systems and methods provide advanced network tracing techniques in the data plane. A data plane packet processing system can receive a request to trace a class of network traffic. The system can receive a plurality of packets. The system can determine on a per packet basis whether to trace the plurality of packets. The system can mark a trace flag associated with a first packet in response to determining that the first packets corresponds to the class of network traffic. The system can capture a trace entry for the first packet in response to determining that the tracing flag has been marked. The trace entry can be configured to include or exclude a packet count, a packet header, a packet payload, and/or processing information. In addition, the trace buffer for storing trace entries can be configurable (e.g., fixed-size buffer, circular buffer, or dynamic buffer).
