摘　　要：针对标签交换路径的设计与维护问题,提出基于故障恢复模型的MPLS VPN动态路径管理算法。该算法在备份路径设计准则的基础上,测试全连通MPLS VPN中备份路径可用性的条件,利用快速备份路径构造算法,在多故障发生时,自动地构造满足客户故障恢复需求的VPN路径,从而使VPN业务受干扰程度最小。This paper put forward the algorithm to dynamically manage MPLS VPN path based on failure recover model. This method could dynamically configure the service paths of MPLS VPN satisfying the resilience requirement from the customers. Specifically, described backup path design rules and derived the conditions for testing the availability of feasible backup paths satisfying the resilience constraints in a full mesh MPLS VPN. And presented fast backup path construction algorithms which could make the MPLS VPN service to be available with minimal disruption, satisfying the resilience requirement from the customers.
