ABSTRACT:
Technology for rerouting a data stream in a communication circuit switched mesh network comprising one or more cross-connecting nodes, the data stream comprises a plurality of data frames each associated with at least one overhead byte, and the rerouting is performed by using a path identifier while switching the data stream at one or more cross-connecting nodes; the path identifier is carried by at least one overhead byte associated with at least one of the data frames.
