1 ASON 现状ASON(Automatically SwitchedOptical Network,自动交换光网络)是指在选路和信令控制之下完成自动交换功能的新一代光网络。它是一种标准化的智能光传送网,被广泛地认为是下一代光网络的主流技术。ASON 第一次将信令和选路引入传送网,通过智能的控制层面来建立呼叫和连接,使交换、传输和数据3个领域又增加了一个新的交集。在传统的传送网中引入动态交换的概念不仅是几十
1 Status of ASON ASON (Automatically Switched Optical Network) is a new generation of optical network that performs automatic switching under the control of routing and signaling. It is a standardized smart optical transport network that is widely recognized as the mainstream technology for next generation optical networks. For the first time, ASON introduced signaling and routing into the transport network, establishing calls and connections through intelligent control planes, adding a new intersection to the three areas of exchange, transport and data. In the traditional transport network to introduce the concept of dynamic exchange is not only dozens
