摘　　要：智能光网络是在光路由和信令控制下完成自动交换连接功能的新一代光网络。在传输带宽和业务应用需求的双重驱动下,智能光网络作为光传送网的发展趋势得到越来越多的关注。介绍并分析了目前智能光网络的结构特点,在基于GMPLS与ASON相结合的新一代智能光网络模型的基础上,主要探讨了智能光网络的保护与故障恢复技术以及基于GMPLS信令扩展的生存性策略。ION is a new generation optical network which can complete automatic switching and linking function under the control of optical routing and signaling.It is considered as the trend of optical transmission network and gets more and more focus under the dual drive of transmission bandwidth and service application demand .First the configuration characteristic of current intelligent optical network is introduced and analyzed in this paper. And then on the base of a new generation ION model namely the combination of GMPLS and ASON, the protection and restoration technologies and the survival tactics based on extended GMPLS signaling are mainly discussed.
