基于SDH的自动交换光网络是指传送平面采用SDH交换方式的自动交换光网络,它通过引入控制平面,实现了网络资源的实时按需分配,从而实现光网络的智能化。自动交换光传送网是未来光传送网的发展方向,是一个容量更大、高度灵活、智能管理及动态配置的光传送网。结合基于SDH的自动交换光传送网的特点,对其传送平面、管理平面和控制平面安全保密技术进行了研究和论述,并提出了相应的设计思路和解决方案。
SDH-based automatic switched optical network refers to the SDH-switched automatic switched optical network in the transmission plane. By introducing a control plane, real-time on-demand allocation of network resources is realized, thereby realizing the optical network intelligent. Automatic switching optical transport network is the future direction of the development of optical transport network, is a larger capacity, highly flexible, intelligent management and dynamic configuration of optical transport network. Combined with the characteristics of SDH-based automatic switched optical transport network, the paper studies and discusses the security technologies of transport plane, management plane and control plane, and puts forward corresponding design ideas and solutions.
