摘要
5G网络的流量激增与业务隔离化承载需求为光传送网带来了端到端协同、网络切片管理等新的管控需求,南北向接口作为管控架构中协同互通的关键,是目前光传送网管控领域研究的重点。提出了面向5G应用场景的软件定义光传送网(SDOTN)管控总体架构,并在架构研究基础上,分别对南向接口及北向接口的国内外标准化现状及产业界动态进行了研究梳理,通过比较不同接口技术的特点与缺陷,对未来光传送网南北向接口的标准化趋势与技术研究方向给出了分析判断。
The traffic surge and service isolation demand of 5G service have brought new management and control requirements such as end-to-end collaboration and network slice management to the optical transport network.As the key to collaborative intercommunication,northbound and southbound interfaces in the management and control architecture is the focus of current optical transport network management and control research filed.The 5G application oriented software defined optical transport network(SDOTN) management and control architecture is proposed firstly.Based on the architecture,this paper studies and analyzes the standardization status and industry application status of northbound and southbound interface in detail. By comparing the characteristics and defects of different interface technologies,the standardization trend and technology research direction of north-to-south interface of optical transport network in the future are analyzed and judged.
