主要介绍智能光网络ASON技术的特点,阐述在3G时代,采用ASON组网的方案和优势。ASON是在选路和信令控制下,完成自动交换功能的新一代光网络,是一种标准化的智能光传送网,代表了未来智能光网络发展的主流方向,是下一代智能光传送网络的典型代表。ASON首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、传送、数据三个领域又增加了一个新的交集,实现了真正意义上的路由设置、端到端业务调度和网络自动恢复,是光传送网的一次具有里程碑意义的重大突破,是下一代光网络的主流技术。
Introduces the characteristics of intelligent optical network ASON technology, described in the 3G era, using ASON networking solutions and advantages. ASON is a new generation of optical network that completes automatic switching under the control of routing and signaling. It is a standardized intelligent optical transport network, which represents the mainstream of the future development of intelligent optical networks and is the next generation of intelligent optical transport networks Typical representative. ASON for the first time the signaling and routing into the transport network, through the intelligent control plane to establish calls and connections, so that the exchange, transmission, data has added a new intersection of the three areas, to achieve the true sense of the routing settings, the end End-to-end service scheduling and automatic network recovery is a major breakthrough in optical transport network and is the mainstream technology in the next generation of optical networks.
