摘要： A system and method for processing packets of information includes an ingress module. The ingress module receives a plurality of packets of information from a first network. The ingress module determines the type of each of the plurality of packets. A route server module is coupled to the ingress module. The route server module sends a distributed processing request to the ingress module. The ingress module receives the distributed processing request and, responsively, performs a first set of processing operations on selected ones of the plurality of packets. The selected ones of the plurality of packets are of a first type. The ingress module forwards others of the plurality of packets of information to the route server module. Each of the others of the plurality of packets are of a type distinct from the first type. The route server module receives the others of the plurality of packets of information and performs a second set of processing operations on the others of the plurality of packets of information.

摘要： A primary LNS, a peer LNS and a LAC are coupled to each other via a network A CPE is coupled to the LAC. A first tunnel is established between the CPE and the LAC using the network and information is transmitted through the first tunnel. A determination is made as to whether the primary LNS is overloaded or inoperative. State information is offloaded from the primary LNS to the peer LNS. If the primary LNS is inoperative or overloaded, a second tunnel is established from the CPE to the peer LNS using the state information. Information is transmitted though the second tunnel.
