Abstract
Method and apparatus are presented which define generic cross-connect primitives that enable the implementation of 1+1 protection in a mesh configured optical network. Such primitives are capable of supporting both 1+1 network protection as well as 1+1 client/access protection, or both. Further, the invention supports multicast applications at no additional architectural cost.
