对于传送网来说,未来的光网络业务远不只是一个更大的波长管道,必须加快业务部署速度,及时对用户需求予以反映,同时拓宽业务范围、提高QoS,开发具有利润增长点的新应用。ASON的特点使其有别于传统的传送网概念,传统的传送网只涉及到信号的传送、复用、交叉连接、监控和生存性处理,不含交换功能,而ASON除了具备以上功能外,还能实现动态、自动地实现传送、交换和建立连接的功能;同时,为了满足目前电路交换和分组交换业务的需求,ASON同时引入了信令和路由的概念,以吸取两类网络的优点同时又避免它们各自的缺点;此外,ASON支持多种客户信号,是一种独立于客户和技术的网络。
For transport network, the future of optical network business is much more than just a larger wavelength of the pipeline, we must speed up the deployment of business, timely response to user needs, while broaden the scope of business, improve QoS, the development of new applications with profit growth point . ASON features make it different from the traditional transport network concept, the traditional transport network involves only the signal transmission, reuse, cross-connect, monitoring and survivability, without switching capabilities, and ASON addition to the above features, At the same time, in order to meet the current circuit switching and packet switching services, ASON also introduced the concept of signaling and routing to learn the advantages of both types of networks at the same time But also to avoid their respective shortcomings; In addition, ASON supports a variety of customer signals, is a network independent of customers and technology.
