摘要
在政策推动和技术演进双因素驱动下,SDH的退网工作已经提上日程,VC-OTN作为SDH的替代已开始规模化部署.基于退网时间和时机的选择差异,给出了保守型、主动型和积极型三种退网思路,并结合SDH的网络和业务现状的分析,提出SDH与VC OTN融合组网方案,即保留SDH接入层,对核心层和汇聚层进行退网的积极型思路可实施性较强,满足实际情况.针对SDH与VC-OTN在数据面、管理面和控制面是否融合,提出了同厂家情况和异厂家情况的退网策略.
Abstract
Driven by both policy promotion and technological evolution,the withdrawal of SDH has been put on the agenda,and VC-OTN,as a replacement for SDH,has begun to be deployed on a large scale.Based on the differences in the timing and timing of network withdrawal,three types of network withdrawal strategies were proposed:conservative,proactive,and proactive.Combined with the analysis of SDH's network and business status,a network integration scheme for SDH and VC-OTN was proposed,which preserves the SDH access layer and performs net-work withdrawal on the core layer and aggregation layer.The proactive approach has strong fea-sibility and meets the actual situation.Propose a network withdrawal strategy for the integration of SDH and VC-OTN in terms of data,management,and control,based on the situation of the same manufacturer and different manufacturers.
