Parted Shared Restoration Scheme for WDM Networks
WDM光网络故障的快速共享恢复方案

The path restoration can share more capacity if the number of links of work path is 2 or 3 was found through simulation. Based on this result, a novel restoration scheme segmented shared restoration (SSR) was proposed. The end to end work path is divided into several segments and each segment is provided backup path. Restoration time gets sharp drop at the cost of a litter increase of utilization of capacity in SSR. Partition rule and realization of SSR is explained. Through theoretical analysis and computer simulation the performance of SSR was demonstrated.
