【摘要】 MPLS组播网络能快速有效地传输数据,其中的路径恢复机制确保提供持续的网络服务。该文提出了一种基于资源共享的MPLS组播网络中的路径恢复方案,该方案在每条链路的入口处保存一个链路资源使用数据库,使用基于共享资源且提供带宽保证的备份路径计算方法来预先建立备份路径,能优化网络资源的利用并减少切换时延。更多还原

【Abstract】 MPLS multicast networks can forward the data packets fast and efficiently, and the mechanism of path recovery in MPLS multicast networks ensures the persistence of network services. This paper proposes a path recovery solution with shared resources in MPLS multicast networks. The solution maintains a database in the entry of every entry that records the utilization of link resources, and pre-establishes the backup path with bandwidth guaranteed and shared resources. This solution can optimize the utilization of network resources and lessen the switching duration.更多还原
