在软件定义光传送网络(software defined optical transport network,SDOTN)体系架构中,要求厂商控制器系统通过北向接口接入光传送网络(optical transport network,OTN)业务协同器系统。但是目前没有统一的北向接口标准,这给SDOTN跨域跨厂商端到端业务自动开通带来了比较多的问题。阐述了OTN控制器北向开放接口标准现状及问题,从网络模型角度对当前主流的电话应用编程接口(telephone application programming interface,TAPI)和流量工程网络抽象与控制(abstraction and control of traffic engineering network, ACTN)北向接口标准进行了比较和分析。最后,介绍了中国联通在 ACTN 统一接口模型标准化和管控系统建设两个方面的研究实践,并对后续研发方向进行了展望。
In the software defined optical transport network (SDOTN) architecture
the manufacturer’s controller system is required to be connected to the optical transport network (OTN) orchestrator system through the northbound interface.However
there is currently no unified northbound interface standard
which brings many problems to the automatic provisioning of cross-domain and cross-vendor end-to-end services in SDOTN.The status and problems of OTN controller northbound open interface standards were expounded
and the current mainstream transport application programming interface (TAPI) and abstraction and control of traffic engineering network (ACTN) northbound interface standards from the perspective of network models were compared and analyzed.Finally
the research practice of China Unicom in the standardization of ACTN unified interface model and the construction of management and control system were introduced
and an outlook on the follow-up research and development direction was provided.
