支持流量工程的MPLS信令协议及其实现技术

MPLS Signaling Protocol Supporting Traffic Engineering and Its Implementation Technology

本文分析了两种支持流量工程的MPLS信令协议:基于约束路由的标签分配协议CR-LDP和扩展的资源预留协议RSVP-TE,论述了在VxWorks操作系统上实现CR-LDP协议的方法和技术。通过在网络环境中进行测试,证实了所实现的信令协议可以很好地支持流量工程,并且能够有效地提高数据转发速率。

In this paper,two sets of the MPLS signaling protocol,CR-LDP and RSVP-TE,are analyzed.After this,the implementation of CR-LDP on VxWorks is provided.The experiments prove the signaling protocol can support the traffic engineering well,and it can effectively improve the speed of forwarding data packets.
