| 摘 要： | 多协议标记交换(Multi-protocol label switching,MPLS)这项新兴技术,因其相对IP分组技术具有更高的质量保证和流量工程控制特性,在下一代网络中发挥着越来越重要的作用。在流量工程MPLS-TE(Traffic Engineering,TE)中,信令协议用以提高MPLS中流量工程的性能。该文对MPLS-TE中常用的信令协议基于流量工程的资源预留协议(Resource Reser-vation Protocol-Traffic Engineering,RSVP-TE)和基于路由受限标签分发协议(Constraint-Routing Label Distribution Protocol,CR-LDP),从标签交换路径(Label Switching Path,LSP)的稳定性和灵活性两个方面进行了对比分析。

| Abstract: | Multi-protocol label switching（MPLS） is rapidly emerging technology,due to its higher quality guarantee and traffic engineering,which plays a key role in next generation networks.In MPLS traffic engineering signaling protocols are used to increase the performance of traffic engineering in MPLS.This paper presents an analysis of MPLS signaling protocols for traffic engineering.The comparative study of signaling protocols RSVP-TE and CR-LDP is conducted on the aspects of LSP reliability and LSP adaptability,the results show that MPLS provides improved network performance for heavy traffic environments. |
