摘　　要：光传送网是网络技术发展的重要基础,对新一代光网络ASON体系结构及其功能的研究正不断深入。当前的光网络虽然能够提供巨大的容量,但相对于IP网络却很不灵活,其大部分的限制都是由于这样的事实,就是操作的手动性或复杂性,因此降低了网络管理系统的反应。ASON是一种光传送网,具有动态连接能力,这种能力是通过使用一个能执行呼叫和连接控制功能的控制平面来完成的。Optical transport network is an important foundation of network technology development. The architecture and function of ASON for new generation optical network are studied. Current optical networks, although offering enormous capacity, are quite inflexible compared to its IP network. Most of their limitations are due to the fact that they are operated manually or via complex and slow reaction of network management systems. ASON is an optical transport network that has dynamic connection capability. This capability is accomplished by using a control plane that performs the call and connection control functions.
