Abstract: An embodiment of the invention provides a flexible bandwidth advertisement method that can reduce the number of routing updates that are sent in a network. In an embodiment of the invention, a method of reducing available bandwidth updates in a link in a communication system is provided. The method includes setting a range of threshold values. An actual available bandwidth in the link is then changed. If the actual available bandwidth changes from a first value within the range of threshold values to a second value within the range of threshold values, then a transmission of an available bandwidth update on the link is then prevented.

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.
