摘要
随着信息技术的迅速发展,光传送网作为信息传输的重要基础设施,面临着巨大的挑战和机遇.传统的光传送网架构复杂、管理困难,难以满足日益增长的业务需求.软件定义网络(Software Defined Network,SDN)技术的出现,为光传送网的发展带来新的机遇.文章介绍SDN技术的基本概念与特点,分析SDN在光传送网中的优势,详细阐述SDN技术下的光传送网架构设计,包括控制架构、南北向协议构建设计以及标准化进展与潜在应用.通过此研究,旨在为光传送网的未来发展提供新的思路和方法.
Abstract
With the rapid development of information technology,optical transport network,as an important infrastructure for information transmission,is facing great challenges and opportunities.The traditional optical transport network is complex in structure and difficult to manage,and it is difficult to meet the growing business needs.The emergence of Software Defined Network(SDN)technology brings new opportunities for the development of optical transport networks.This paper introduces the basic concepts and characteristics of SDN technology,analyzes the advantages of SDN in optical transport network,and expounds in detail the architecture design of optical transport network under SDN technology,including control architecture,North-South protocol construction design,standardization progress and potential application.Through this research,it aims to provide new ideas and methods for the future development of optical transmission networks.
