This white paper discusses a synchronous optical network/synchronous digital hierarchy (SONET/SDH) protection scheme for meshed networks. With PPMN, a network planner can design a mesh that utilizes both protected and unprotected spans at various line rates. In the event of a failure on one route, connection is reestablished through another path in the mesh in less than 50 milliseconds (ms). This offers network planners flexibility they can use for mesh networks today.
