Abstract

A ring interconnection architecture (10) is disclosed that includes an interconnection switch (20) having a plurality of N x N switching fabrics that interconnect two or more optical channel shared protection rings. Each switching fabric (20) includes a plurality of switch states corresponding to a failure condition in either of the protection rings. The ring architecture (10) also provides a plurality of node switches disposed at each node in the optical channel shared protection rings. Each node switch includes a ring switch mode that is responsive to multi-channel failures and a span switch mode that is responsive to single wavelength channel failures. Thus, the interconnection architecture (10) provides independent protection for both multi-channel failures and single channel failures in any of the interconnected rings. The node switches act in concert with the interconnection switch to provide protection for both multi-channel failures, single channel failures, and switch fabric failures.
