ABSTRACT:
An apparatus and method that extend the automatic protection switching protocol to address at least 256 network nodes. By using overhead bytes as extended APS node IDs, large single ring SONET/SDH systems can be avoided. This means APS messages that force every node into a single ring can be avoided and recovery performance from a break in the ring or a node fault can be improved. The protocol for the extended automatic protection switching channels takes multiple extended APS node IDs from tributary lines and merges those extended APS ID's into a single SONET/SDH stream on another line. Placement of the extended APS node ID's in the overhead bytes of SONET/SDH frames allows easy relay around each SONET/SDH ring.
