Abstract

This paper addresses dynamic restoration to the scenario of single link failure for survivable traffic grooming in WDM mesh networks. Two restoration schemes are proposed, dynamic restoration at connection granularity (DRAC) and dynamic restoration at lightpath granularity (DRAL). DRAC routes a failed connection to a new multihop path, while DRAL routes a failed lightpath to a new lightpath or other available lightpath. Then we compare the two restoration schemes with other schemes for survivable traffic grooming.
WDM网络中可生存业务疏导的两种动态恢复方案
本文研究了WDM网状网络中单链路故障下的动态恢复问题。提出了两种恢复方案:连接粒度动态恢复(DRAC)和光路粒度动态恢复(DRAL)。DRAC将失败的连接路由到新的多跳路径,而DRAL将失败的光路路由到新的光路或其他可用的光路。然后,我们将两种恢复方案与其他可生存交通疏导方案进行了比较。
