摘　　要：M PLS已经成为NGN发展的重要技术,为了通过有效流量工程来达到提供Q oS和优化资源分配的目的,可以用混合整数数学方程(优化)技术来模拟路由问题,可以使构建、应用和维护网络成本最低,因此本文提出了一种基于M PLS网络链路计算的优化模型算法,使其应用于M PLS网络规划,根据容量和网络结构限制以及标签交换路径生存能力来安排路由,并结合两个网络实例得到证实。MPLS has becomed the important technique in NGN＇development, contributing for doing an efficient Traffic Engineering （TE） in order to provide the QoS and to optimize resource allocation. For this purpose, it is possible to apply Mixed Integer Mathematical Programming （optimization） techniques to model routing problem minimizing implantation, operation and maintenance network costs, we present an optimization model applied to the MPLS network planning, which assign paths based on capacity and network architecture constraints, considering LSP survivability. The model is consolidated in two case studies, applying them to plan a MPLS network. The main characteristics of the MPLS concerning to the network planning approach are presented.
