  • Patent number: 5838924
    Abstract: A Virtual Path Group (VPG) technique that utilizes network elements (NEs), i.e., nodes, that are visible to ATM specific defects, and allows for fast ATM virtual connection/restoration with a minimum of processing. This is realized by employing a Virtual Path Group transport architecture comprises at least one (1) working route, one (1) protection route, and VPG bridge and selector functions at each end of the routes. It is applicable to 1+1, mesh and ring protection switching and is extensible to any virtual connection segment or end-to-end network (cross-subnetwork) virtual connections, and extensible to 1:1 and M:N protection switching. Additionally, the protection switching arrangement of the invention includes an architecture for the Virtual Path Group (VPG) concept in which the associations among individual ATM virtual channels (VP/VCs) and VPGs are maintained entirely within the network element management function.
