摘要：This paper proposes a protection scheme for the WDM network. The emergence of WDM technology has provided an unprecedented opportunity to dramatically increase the bandwidth capacity of telecommunications networks. In protection schemes, there are spare resources reserved for each protected part while those resources are not used under normal conditions. So restoration usually has better resource utilization than protection. Shared protection means multiple protected parts share the same spare resource, while dedicated protection means each protected part has dedicated spare resource. So shared protection schemes usually have better resource utilization than dedicated resource utilization. The proposed method provides a good scheme and an effective framework for protection in WDM networks.
