【摘要】 网络可靠性已经成为网的一个重要问题。目前关于网可靠性的讨论集中于的故障恢复机制。提IPIPMPLSIETF出了两种故障恢复模型:保护交换和重路由,每种模型的恢复时间和资源开销是不同的。该文提出一种基于MPLSMPLS的分级故障恢复机制MBCR,它可以保证应用对可靠性和QoS的要求,同时使网络资源得到充分利用。更多还原

【Abstract】 Network reliability has become a key issue of IP network. The current discussion about IP network reliability focuseson MPLS recovery mechanism. IETF has proposed two types of MPLS recovery models: protection switching and rerouting, which have different recovery time and resource utilization. This paper proposes a MPLS-based classified recovery mechanism, which can satisfy the applications’ requirements about reliability and QoS, and utilize the network resource efficiently at the same time.更多还原
