A system for scheduling a conference between callers includes a database that stores scheduling information indicating at least a start time, a duration, and a maximum number of callers for one or more scheduled conferences, the scheduling information reflecting available conferencing resources. A server complex coupled to the database communicates, to a requesting Internet Protocol (IP) user, at least one page including one or more scheduling input fields. The server complex receives scheduling input from the requesting IP user for a requested conference according to the scheduling input fields. The server complex accesses the database to determine, according to the scheduling input, whether sufficient resources are available for the requested conference. If so, the server complex allocates at least some available resources to the requested conference and generates confirmations of the requested conference for communication to the callers.

A network is provided herein comprising a plurality of network resources, and at least one network cluster having a plurality of cluster members. Each member of the cluster may be configured for utilizing one or more of the network resources and for tracking usage thereof. For example, each member of the cluster may include one or more token buckets for tracking that member's usage of the network resources. At least one member of the cluster (i.e., a “reservation coordinator”) may include a first set of computer-executable instructions for receiving network traffic destined for a particular network resource at a first rate (i.e., a maximum average sustained rate). In addition, the reservation coordinator may include a second set of computer-executable instructions for distributing the first rate among at least a subset of the cluster members. In some cases, each member of the cluster may include a third set of computer-executable instructions for changing how the first rate is distributed among members of the subset. For example, the third set of computer-executable instructions may include instructions for attempting to reserve a substantially larger or smaller portion of the first rate.

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.
