摘要
MPLS流量工程通过优化IP网络资源的使用以提高网络性能,并通过结合约束路由和面向连接的标记交换路径提供了端到端的QoS保障。该文在总结现有IPQoS主要技术的基础上,进一步论述了MPLS流量工程的主要体系结构和实现机制。并通过实验对比分析了MPLS流量工程相对于传统IGP在优化网络资源和支持显式路由LSP的优势并测试了对IP网络QoS的提升。
MPLS traffic engineering can improve IP network performance through usage optimization of network resource and provide end-to-end QoS provision through combination Constraint Based Routing and connection oriented label switch path,On the basic of main IP QoS technology summarization,the article dissertate the system architecture and implementation mechanism of MPLS traffic engineering.Furthermore,this paper analyzes the advantages of MPLS traffic engineering in the aspect of resource optimization and explicit route LSP capability over traditional IGP technology through experiment,and tests the IP QoS improvement for IP network.
