ABSTRACT:
A system for managing virtual circuits and determining proper routing of packets in a network environment. The network includes a connection-oriented subnetwork and an arrangement of routers coupled to the connection-oriented subnetwork. The system determines paths to each exit router by considering all possible paths through the connection-oriented subnetwork. The system also determines paths to each exit router by considering existing virutal circuits through the connection-oriented subnetwork. Finally, the system determines and establishes a most beneficial new virtual circuit for the network. Additionally, the rate at which new virtual circuits are established may be regulated by the system.
