ASON体系结构及存在的问题研究

Research in ASON Architecture and the Existent Problems

介绍了自动交换光网络(ASON)——一种具有灵活性、高可扩展性的能直接在光层上按需提供服务的光网络的发展情况和技术特点,分析了ASON的体系结构,包括3个平面,3个接口、3种连接。最后指出了ASON在规范和应用中存在的问题。

The development and the characteristic of Automatic Switched Optical Network （ASON） , which is a highly flexible and extensible infrastructural network, can provide services directly at the optical layer are described in this paper, Researched in this paper is the architecture of ASON, the architecture is consists of three p lanes, three kinds of interfaces and three types of connections. The existent problems of ASON in criterion and application are summarized.
