摘　　要：自动交换光网络(ASON)实现光通路的自动连接和拆除,使原来的静态通路变成了动态通路。ASON具有智能化自动完成光网络交换连接的能力,通过分析ASON工作原理,着重介绍了自动交换光网络的技术特点、智能化的发展趋势,以及ASON在城域网和核心网中的应用,强调了备份路由可提高网络抗毁性能要求。In the Auto Switch Optical Network, the optical paths can be connected and disconnected automatically, which makes originally static paths become dynamic paths. ASON has the capability of intelligently auto setup the optical network switch connection. With the analyses of its operation principle, the features and intelligent development trends of ASON are presented. And its applications in the MAN and backbone network are introduced. It＇ s emphasized that the backup muting can enhance the anti-damage performance requirements of the network.
