| 摘 要： | 针对现有波分复用（WDM）网络保护机制倒换时间长、资源消耗较大的问题，提出了一种低开销的动态1＋N专有分段保护（DSDP）策略，能够根据当前网络资源耗费情况动态地确定需要保护的网元，采用线性编码方法，利用单个工作路径对多个工作路径进行专有保护。仿真验证表明，本文策略能极大地降低用于保护的网络资源消耗，同时能有效地利用光...

| Abstract: | In order to solve the issues of long switching time and high resource consumption for protection in wavelength division multiplexing(WDM) network,an effective low-cost dynamical segmented 1+Ndedicated protection strategy is introduced.According to resource consumption condition,the strategy can dynamically determine the segments for protection.Based on network coding,a single backup path can be established to provide dedicated 1+Nprotection for multiple working paths.Simulations show that the st... |
