摘要: The invention provides a method and system for coupling a SONET/SDH network to a routing network that does not have a single point of failure. Multiple routers are coupled between the SONET/SDH network and the routing network, one for each data path; for example, a first router for the working data path and a second router for the protection data path. The routers intercommunicate to force APS to switch data paths bidirectionally, so as to allow only a single router for each data path.
