摘要： 为提高网络资源的利用率,在基于Local故障恢复方案的前提下,提出了一种路由算法,这种算法在确定工作LSP的同时也确定好后备LSP,并使工作路由和后备路由带宽之和最小。

Abstract: The article proposes a routing algorithm based on local fault restoration method for improving utility rate of network resource.In the method,the backup path is also found when the work path is forund,and the total bandwidth of the work path and the backup path is minimum.
