Virtual horizontally-scalable packet broker systems and methods for distribution of session-based network traffic

Abstract:

Virtual horizontally-scalable packet broker systems and methods are disclosed for distribution of session-based network traffic. One or more distributors along with a plurality of ingress processors and egress processors are operated within a virtual processing environment to forward session-based network traffic to network tools. The session-based network traffic includes user packets and control packets associated with user sessions. In addition, one or more session controllers are also operated within the virtual processing environment to dynamically control numbers of virtual processing nodes operating as the distributors, the ingress processors, and the egress processors. User packets are processed and distributed by the distributors, ingress processors, and the egress processors. Control packets are processed and distributed by the distributors, session controllers, and egress processors. The egress processors can include initial and secondary egress processors. In one embodiment, the session-based network traffic can be GTP traffic including GTP-C and GTP-U packets.
