摘　　要：随着MPLS技术的广泛应用,人们对MPLS网络的可靠性要求越来越高,支持MPLS快速重路由的通信设备越来越多。本文主要介绍了如何扩展LDP模块和MPLS模块,以实现基于IP FRR的MPLS快速重路由功能,给出了系统各模块之间的关系、LDP模块对路由模块的路由通知消息的处理流程图以及MPLS模块中转发表项的结构。最后组网测试,证明该扩展设计具有快速重路由功能。With the wide application of MPLS technology, people＇ s demand on the reliability of MPLS network is getting higher and more and more communication apparatuses support MPLS Fast Re-routing. This paper mainly introduced the way of extending LDP module and MPLS module to implement MPLS Fast Re-routing based on IP FRR, showed relationship between modules, flow charts of handling with route messages from Route module of LDP module and the structure of forwarding entry in MPLS module. Finally, this paper carried out system test and the result shows that the design put up in the paper can achieve the function of fast re-routing.
