该文首先分析了IP/MPLS over WDM网络单层生存性和多层联合生存性,并就生存性策略的性能进行对比,然后对多层空闲资源分配进行了研究。
This paper first analyzes the survivability of single layer and joint survivability of IP / MPLS over WDM networks, and compares the performance of survivability strategies. Then the allocation of multiple layers of idle resources is studied.
