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。 M PLS has become an important technology for the development of NGN. In order to achieve Q oS and optimize resource allocation through effective traffic engineering, mixed integer mathematical equation (optimization) technology can be used to simulate routing problems, which can make network construction, application and maintenance Therefore, this paper proposes an optimization model algorithm based on MPLS network link calculation, which is applied to MPLS network planning. The routing is arranged according to the capacity and network structure constraints and the survivability of the label switching path, and combined with two Network instance is confirmed.
