An access server architecture, and methods for use of the architecture to increase the scalability of and balance processor load for a network access server device, are disclosed. In this architecture, packet forwarding and packet processing are distributed amongst cards serving low-speed access lines (i.e., line cards). Thus, as the number of line cards expands, forwarding resources are expanded in at least rough proportion. The NAS route switch controller and the high-speed ports used to access the network are largely relieved of packet processing tasks for traffic passing through the server. The egress port uses a distribution engine that performs the routing lookup for packets received at the high-speed interface, tags the packets with an adjacency table pointer, and sends them to the appropriate forwarding engine for packet processing. The route switch controller, largely uninvolved in the processing of packets, updates routing information needed by each distribution or forwarding engine.

The present invention provides a unique system and method that facilitates reducing network traffic between a plurality of servers located on a social-based network. The system and method involve identifying a plurality of vertices or service users on the network with respect to their server or network locations. The vertices' contacts or connections can be located or determined as well. In order to minimize communication traffic, the vertices and their connections with respect to their respective server locations can be analyzed to determine whether at least a subset of nodes should be moved or relocated to another server to facilitate mitigating network traffic while balancing user load among the various servers or parts of the network. Thus, an underlying social network can be effectively partitioned. In addition, the network can be parsed into a collection of nested layers, whereby each successively less dense layer can be partitioned with respect to the previous (partitioned) more dense layer.
