摘要：Due to the frequent occurrence of fiber cuts and the traffic loss a failure can occur, network survivability becomes a critical concern in network design and operation. As networks migrate from ring based networks to mesh based networks, because its inefficient resource usage, researches on survivable WDM mesh network have received increasing attention. In this paper, we analyze the protection principle of WDM optical network, propose a protection method for optical network. Protection schemes can be divided into link protection, path protection, and partial path protection schemes. Path protection can be further subdivided into dedicated path protection and shared path protection. ? 2010 IEEE.
