摘　　要：介绍了未来最有前途的网络解决方案-GMPLS技术及其生存性策略。首先简要介绍了GMPLS技术,并在此基础上重点讨论了GMPLS与MPLS技术在体系结构、工作流程、路由协议和信令协议方面的联系和区别,尤其是在引入光网络后在这些方面所做的扩展与更新。接着论述了GMPLS技术的生存性策略,分析了生存性研究的现状和待解决的关键问题,并对恢复机制中的重选路由算法做了详细的介绍。This article proposes the most prospective network scheme in the future- the technology of GMPLS, and its survivability strategy. First we discuss the relationship and difference between GMPLS and MPLS on architecture, working process, routing and signaling protocols, especially the enlargement and renewal on these aspects when the optical network is introduced. Then we talk about the survivability strategy of GMPLS, analyze the current research situation and the main problem to be solved. At last we introduce the rerouting mechanisms in detail.
