专线业务的高速发展驱动光传送网从运营商的基础网络发展为直接面向客户的高品质专线业务承载网。随着 MSTP的退出,OTN成为实现光业务网的主要技术。分析研究了 OTN承载专线业务的关键技术及演进,研究OTN多域级联保护中存在的问题并推动在ITU-T进行标准修订,研究并解决域间采用高速接口互连时异厂商设备间的互通问题。提出了运营商通过SDN与OTN相结合建设高品质政企专网的发展方向,推动在IETF制定基于ACTN的SD-OTN控制器北向接口标准和YANG数据模型,在中国通信标准化协会制定接入型光传送网(OTN)的设备管控技术要求,实现南向接口标准化和OTN网络的开放解耦。分享了中国联通在业界开发并部署首个基于SDN智能管控的OTN政企精品网的成果。
The rapid development of leased line services has transformed the optical transport network from operator's basic network to leased line service network.With the withdrawal of MSTP
OTN has become the main network technology for high-value leased lines.Several key technical solutions and evolution of OTN carrying leased line were analyzed and researched.The problem of cascade protection in multi-domain OTN was researched.Interoperability of different venders’ equipment was researched and solved.SDN and OTN were proposed as the development direction for high-quality leased lines.ACTN-based SD-OTN controller northbound interface standard and YANG model
technical requirements of management and control for access OTN equipment were promoted in IETF and CCSA separately
which would promote decoupling of OTN network.China Unicom’s leading experience of development and deployment of SDN orchestrator on OTN for high quality leased line was shared.
