Novel design of G. ODUSMP to achieve sub-50 ms performance with shared mesh protection in carrier networks

This paper describes the first practical implementation of shared mesh protection with <50 ms performance using the emerging standards G.808.3 & G.ODUSMP. It also presents the performance benefits of this implementation demonstrating 20-26% network cost savings vs. 1+1 protection and a maximum protection switch time substantially less than 50 ms.
