一种MPLS流量工程显式路由算法

A Policy and Traffic-classification Based Explicit Routing Algorithm for MPLS Traffic Engineering

提出一种基于策略和流分类的MPLS(Multi-Protocol Label Switch)显式路由算法—PTCR(Policy and Traffic Classi-fication Routing).算法综合考虑网络流量、资源、管理策略等要素,根据网络流量分布特征和网管策略合理配置网络资源.算法能够较好地平衡网络资源的使用,提高网络资源利用率,有效实施MPLS流量工程.

A MPLS traffic engineering explicit routing algorithm based on policy and traffic classification, which is called PTCR, is proposed in the paper. The network traffic profile, network resource allocation and network management policy are taken into consideration in the process of explicit route computation, and thus the network resources are allocated to the specific flow according to the traffic profile and network management policy. The algorithm can improve the utilization of network resource and provide the explicit route for facilitating MPLS Traffic Engineering and network performance optimization effectively.
