| 摘 要： | 区别于传统光网络,ASON引入了控制平面进行网络管理控制。控制平面的引入提供了多种生存性方式,可以进行快速的故障恢复。主要研究了基于通用多标签协议（GMPLS）的ASON控制平面的网络恢复机制,分析了常用的恢复和保护策略。以恢复时间作为性能指标,对传统恢复方案和改进的恢复方案进行了分析,并对其网络恢复时间进行了仿真对比,指出各自的优缺点,提出了未来ASON网络中生存性的发展趋势。

| Abstract: | Different from the traditional optical network,control plane is introduced into ASON to manage the network.The introduction of control plane could supply a variety of survivability types and achieve effective network recovery.The network recovery mechanisms in ASON management plane based in GMPLS are mainly studied,and several common recovery and protection strategies analyzed.With the recovery time as the performance index,as the traditional recovery meehanism and the modified recovery mechanism are discussed.Finally,this paper,based on simulation,points out their respective advantages and disadvan tages,jncluding the survivability development trend in ASON. |
