针对波分复用(WDM) 网络中单链路出错的生存性流量疏导问题,文章提出了一种基于光路的动态恢复机制(DRAL) 。

DRAL 不预留任何资源,当链路出错时,通过在网络中动态地发现资源来对错误链路进行恢复,将一个出错的光路转发到一条新建立的光路或其他可用的光路上-For wavelength division multiplexing (WDM) network, the existence of a single-link error problem of traffic grooming, the article presents a dynamic optical-based recovery mechanisms (DRAL). DRAL does not reserve any resources, when the link error, through the network to dynamically discover resources to restore the link on the error, an error will be forwarded to the optical path of a newly established optical path of light or other available
