CFP: Cooperative Fast Protection

Free registration required

Executive Summary

The authors introduce a novel protection scheme, called Cooperative Fast Protection (CFP), to fight against a single link failure in survivable WDM (Wavelength Division Multiplexing) mesh networks. CFP achieves capacity-efficient fast protection with features of node-autonomy and failure-independency. Though CFP organizes spare capacity into pre-cross-connected cycles, it differs from p-cycle by reusing the released working capacity of the disrupted light-paths (i.e., stubs) in a cooperative manner, and utilizing both the released stubs and the spare capacity on the cycles to set up backup paths.
