摘　　要：　叙述了准同步数字传送网向同步数字传送网,同步数字传送网向波分复用(WDM)光传送网的演进过程。阐明了传统的传送网必然向自动交换光网络(ASON)演进的观点。着重介绍了ASON的体系结构、网络结构、功能特点、控制平面的功能构件、标准接口以及实现ASON控制平面的关键控制协议规范。The evolution of transport network from PDH to SDH, and from SDH to WDM is discussed. The developing trend from traditional WDM optical network to intelligent optical network is analyzed in detail. As a typical presentation of intelligent optical network, ASON is discussed thoroughly, including the system architecture and network framework and major advantage and function component of control plane and standard interface and protocol of control plane.
