随着DWDM(密集波分复用)技术的发展,系统单波已从10 Gbit/s、40 Gbit/s向100 Gbit/s演进,DWDM系统容量已不再是网络发展的瓶颈,如何实现波长端到端的动态配置和调度、提升网络的安全性和利用率则成为关注的焦点.文章简要描述了WSON(波长交换光网络)的关键技术,通过试验网对WSON功能进行验证,并对WSON应用策略进行了探讨.

With the development of DWDM technology,the system single channel transmission rate has evolved from 10 Gbit/s,40 Gbit/s to 100 Gbit/s,so the DWDM system capacity is no longer a bottleneck in the network development.Hence,end-to-end dynamic configuration and scheduling and the network security and utilization improvement have become the focus of attention.This paper briefly describes the key technologies for Wavelength Switched Optical Networks (WSON),verifies the WSON functions through the trial network and explores the strategies for its applications.
