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: An example method for load-balanced IP pool distribution among a plurality of forwarding elements is provided. The method may include assigning a plurality of IP pool chunks to the plurality of forwarding elements, each IP pool chunk comprising a plurality of IP addresses, and receiving, from each of the forwarding elements, information indicative of a load on each forwarding element. The method may further include performing load balancing using the information indicative of the load on each forwarding element to determine whether re-assignment of the plurality of IP pool chunks is needed, and re-assigning at least one IP pool chunk of the plurality of IP pool chunks from a first forwarding element to a second forwarding element based on the load balancing.
