基于多波长光传送网的网络保护与恢复

Protection and Restoration of Telecommunication Networks that based on Multi-Wavelength Optical Transport Networks

介绍了传送网的发展趋势和结构变化 ,分析了原有传送网的一些保护与恢复方式 ,然后着重分析了多层传送网保护与恢复方面的一些问题 ,提出了在基于多波长的多层融合光传送网中如何更好地实现保护与恢复的几种方法及原则 ,并进行了相应的对比和分析。

This paper introduce the development of transport networks and change of structure,analyze some way of protection and restoration of transport networks, especially in multilayer networks , bring up and compare some way of pretection and restoration in multilayer networks,analyze the advantage and shortcome of these way.
