ABSTRACT:
A method and system for restoration of a fiber communication network through optical tributary switching. Multi-port optical cross-switches switch traffic at the tributary side of lightwave terminal equipment in the event of a network failure. Optical tributary switching is implemented in a variety of all-optical core network architectures including separate disjoint path, link-based mesh, and path-based mesh configurations. Network resiliency is enhanced without introducing loss over a high-speed fiber line or trunk.
