ABSTRACT:
A bidirectional logical-ring network employs crossconnect nodes, which partition the network into segments and interconnect segments at the subchannel level to form logical ring structures. All segments are independent, and each segment includes a subset of Add-Drop Multiplex nodes (ADMs) and two pairs of links, one working and one protection. The formation of logical rings from the interconnection of independent segment subchannels preserves the self-healing advantages of conventional bidirectional ring networks and allows greater flexibility to effeciently accommodate bandwidth upgrade requests.
