Abstract

In a packet switched communications system that supports per-hop-behavior differentiated services, an edge packet switched node (32) examines a class of service (CoS) designation requested for a packet (50) to determine if special differentiated service (56) is desired for the packet. If so, the node bypasses the normal per-hop-behavior forwarding mechanism for supporting differentiated services in favor of the initiation of a service providing a dedicated end-to-end path through the system for handing the packet and providing a guaranteed level of quality of service. For instance, with respect to operation within a legacy asynchronous transfer mode (ATM) system, internet protocol (IP) packets or multiple protocol label switching (MPLS) packets may specify a special differentiated service comprising a constant bit rate (CBR) service. In each case, the edge legacy ATM node receiving the packet reads the header to identify that constant bit rate service is being requested, and bypasses the normal per-hop-behavior forwarding mechanism for providing differentiated services in favor of the initiation of a native ATM constant bit rate service.
