骨干ROADM网络融合技术应用及研究

Application and Research of Backbone ROADM Network Fusion Technology

通过分析骨干可重构光分插复用器(Reconfigurable Optical Add-Drop Multiplexer,ROADM)的网络分层分域组网存在的问题,以网络架构扁平化为方向,以网络融合为方法,分别研究不同区域、不同层级的骨干ROADM网络结构。旨在优化骨干ROADM网络结构,降低跨域业务承载的投资成本,提高网络安全性和维护便利性。

By analyzing the problems existing in the hierarchical and sub-domain networking of reconfigurable optical add-drop multiplexer(ROADM),this paper studies the network structure of ROADM in different regions and levels with the flattening of network architecture as the direction and network convergence as the method.This paper aims to optimize the backbone ROADM network structure,reduce the investment cost of cross-domain services,and improve network security and maintenance convenience.
