智能光网络应用和发展

现有的SDH组网方式是为满足静态电路而生,因此具有网络扩展性差、带宽利用率低、安全性差、端到端管理不足以及无法快速满足带宽突发需求等问题。为了满足数据业务增长的需求,智能光网络技术应运而生,智能光网络在传统SDH网络的基础上增加了一个新的层面——控制平面,并相应地在控制平面中引入了路由、信令和链路管理等机制,以实现带宽自动管理。

Application and Development for Intelligent ASON

The existing SDH network is lives for the satisfied static electric circuit, the network has questions for extension bad, the band width use effecicnty low, the security bad, the end-to-end management is insufficient as well as is unable fast to satisfy the band width arise suddenly question, ans so on. In order to satisfy the data service aggregate demand, ASON arises at the historic moment, it increased a new level control plane in the traditional network foundation, and correspondingly introduced the route, the letter in the control plane made with mechanism and so on link management for the band width automatic management.
