几种集成化光互联网实现方案

Optical Communications Technologies and All Optical Networks Several Novel Approaches for Integrated Optical Internet

新技术的开发和使用使得光网络层具有了许多原来只能在高层实现的网络功能，从而为直接在WDM光网络上承载IP业务创造了条件。概括来讲，较好的集成化方案目前主要有三种：一种是IP路由器与WDM直接相连；另一种是基于多协议波长交换（MPLmS）技术的方案；还有基于标签的光突发交换（LOBS）方案。对这三种新型集成光互联网实现方案进行了研究与探讨。

The exploitation and application of technologies introduces some functions that can only be provided by higher layer into optical network layer which will allow even closer integration of IP－WDM layer． Three new approaches for integrated optical Internet namely Router ＋ WDM optical network Multi－protocol Lambda Switching and Labeled Optical Burst Switching are studied in this paper．
