[57] . ABSTRACT
Methods and systems for resource management in a fast packet switching communication network are disclosed. A packet containing an address field identifying a source endpoint and a destination endpoint is received. A bandwidth constraint based upon the source endpoint, but independent of the destination endpoint, is enforced for the packet. In a communication network wherein a plurality of virtual connections are provisioned from a single source endpoint to a plurality of destination endpoints, the bandwidth constraint is associated with bandwidth usage over all of the virtual connections.
