| 摘 要： | 在分析现有MPLS快速重路由算法基础上提出了一种分布式的MPLS快速重路由算法,并给出了算法描述.算法通过划分自治域并行预先建立备份路径,从而降低了原来算法中对整个拓扑预先建立备份路径的复杂度.仿真试验表明该算法在丢包率、重路由成功率上比现有算法有较好的性能.

| Abstract: | A novel MPLS fast rerouting algorithm is presented and described in detail.The algorithm is characterized by dividing the core network into several autonomous domains to make pre-constructed backup path in parallel,thus reduce the complexity.The simu-lation results show the given algorithm generate lower packet loss and higher success ratio. |
