Method and apparatus for providing quality of service routing in a network

摘要

A system for providing quality of service routing functions in a connectionless network having multiple nodes. The system generates a link resource advertisement for each node in the network. Each link resource advertisement includes information regarding link resources available on a particular node in the network. The system also generates resource reservation advertisements for each node in the network. Each resource reservation advertisement includes information regarding a particular node's current reservations for a data flow. Network paths are calculated in response to a quality of service request. The calculations are performed based on information contained in the link resource advertisements and resource reservation advertisements.
