WDM光网络双链路故障混合保户算法
Two-link failure in WDM optical networks with mixed protection algorithm
摘要
Abstract
This paper combined P-cycle and shared path protection for two link failures in WDM optical networks, and put forward a mixed protection scheme whose main idea was as follow: for a given work path, found a primary protection which separated with the work path,and then for each link on the work path looked for a P-cycle protection which partly separated with the primary protection. Finally,the simulation results under three different business models show that the algorithm can achieve a recovery rate of 100% ,and has a lower rejecting rate and resource redundancy.关键词
