Time division multiplexing label switching path establishing method for e.g. synchronous digital hierarchy communication network, involves comparing total number of components with number concerned by established paths to open connection

摘要

The method involves introducing route diverse requested information and information relative to total number of components of virtual concatenation group in a field of signaling message for each of time division multiplexing label switching paths. Each message is read, and a path establishment conforming message is sent. The number is compared with a number of components concerned by the established paths to determine whether all the signaling messages are received, to open synchronous optical networking/synchronous digital hierarchyconnection after establishing all the paths.
