Abstract:

1+1 Mesh Protection provides 1+1 protection for connections across an automatically routed mesh network, where a connection is setup automatically by using an intelligent signaling and routing protocol. 1+1 Mesh Protection can set up, tear down, and reroute both the working path and protect path across the mesh network automatically based on a specified service profile. 1+1 Mesh Protection interoperates seamlessly with traditional 1+1 protection mechanisms such as APS 1+1 protection in SONET networks.
