支持自愈恢复的WMPLS自组网组播协议

基于无线多协议标签交换（WMPLS）协议体系，结合无线移动自组网的特点，提出一种支持自愈恢复的WMPLS信令建立标签交换路径的自组网组播协议RA—WMPLS。该协议基于LDP信令协议做了组播扩展，使用LDP消息进行组播树的建立和维护，并建立LSP自愈恢复机制，既实现组播的功能，又能够快速恢复中断的链路，提高网络的性能。通过构建AdHoc网络仿真模型，仿真对比RA—WMPLS和ODMRP路由协议的性能，并验证了自愈恢复特性。

WMPLS Multicast Protocol for Ad Hoc Network Supporting Recovery

Based on framework of Wireless Multi-Protocol Label Switching(WMPLS) protocol and characteristic of mobile Ad Hoc network,this paper proposes a multicast protocol RA-WMPLS for Ad Hoc network using WMPLS signaling protocol supporting recovery to establish Label Switch Path(LSP).With label messages and the extending of existing messages introducted to LDP signaling protocol,RA-WMPLS sets up and maintains multicast tree.It realizes multicast function,recovers from a link or node failure,improves network perfor...
