在概述DWDM网络保护倒换原理的基础上,重点分析了基于点到点DWDM设备构成的环形网的结构和恢复机制,阐明了基于点到点DWDM设备的组网策略,对防止网络瘫痪、提高服务质量有较强的现实意义。
Based on an overview of the principle of DWDM network protection switching, the structure and recovery mechanism of ring network based on point-to-point DWDM equipment are emphatically analyzed. The networking strategy based on point-to-point DWDM equipment is clarified, which can prevent network from being paralyzed and improve service Quality has a strong practical significance.
