摘要
文章概述了IP、SDH和WDM层网络的生存性技术,重点介绍了光传送网的光层生存性技术与光网络恢复技术,还对故障定位、多层生存性机制的协调等问题进行了简单介绍,最后给出了一个业务配置RWA算法与恢复RWA算法的实际方案。
The survivability techniques for IP, SDH and WDM layers are outlined and emphasis is put on the optical layer survivability techniques and the optical network restoration techniques for OTN. Relative Issues like fault location and coordination of multi-layer survivability mechanisms are briefly discussed. A practical scheme of routing and wavelength assignment algorithms for traffic control and restoration is also introduced.
