Abstract
A system for facilitating bandwidth management in a routing domain is presented. In the system, area bandwidth managers are coupled to a domain bandwidth manager and arranged in accordance with an Open Shortest Path First (OSPF) hierarchical routing topology with the domain bandwidth manager at an upper level of the topology. Each area bandwidth manager is located in a different area of the routing topology in at least one lower level of the topology. The domain bandwidth manager and the area bandwidth managers cooperatively coordinate admission control to a routing domain for facilitating a communication session between a source device and a destination device.
