摘要
针对当前SDH网络业务承载现状以及专线业务承载需求,首先阐述了当前主流传送网技术的特点,对SDH网络上承载业务的迁移方案进行研究,然后据此提出基于VC-OTN技术的政企专网承载方案,并从网络结构规划、网络演进方面构建了VC-OTN技术的应用方案,以此解决SDH业务迁移及网络演进中存在的问题。最后,提出SDH网络替代方案,实现SDH网络协同演进及业务平滑迁移的目的。
In view of the current SDH network service carrying status and private line service carrying demand,firstly,the characteristics of the current mainstream transport network technology are described,and the migration scheme of carrying services on SDH network is studied.Then,a government-enterprise private network carrying scheme based on VC-OTN technology is proposed.The application scheme of VC-OTN technology is constructed from the aspects of network structure planning and network evolution to solve the problems existing in SDH service migration and network evolution.Finally,an alternative scheme for SDH network is proposed to achieve the goal of SDH network cooperative evolution and smooth service migration.
