OSU管控技术标准化与应用研究

Research on Standardization and Application of OSU Management and Control Technology

当前光网络典型业务场景存在对大小颗粒并存、带宽利用率提升的灵活管控和节能需求,光业务单元(Optical Service Unit,OSU)管控技术的软件定义网络(Software Defined Network,SDN)管控和小带宽资源利用优势能很好地解决该问题。通过梳理OSU管控技术国际国内标准化现状,结合OSU技术特点和典型业务场景需求,提出OSU管控架构、管控接口功能架构,详述南北向接口实现原理和管控功能验证方案,为OSU技术在光网络典型业务场景的现网应用提供管控技术支撑。

The current typical optical network traffic scenarios have the requirements of flexible management and energy saving for the coexistence of large and small particles and the improvement of bandwidth utilization,OSU(Optical Service Unit)management and control technology SDN(Software Defined Network)management and small bandwidth resource utilization advantages could be a good solution to this problem.By reviewing the international and domestic standardization status of OSU management and control technology,combining the characteristics of OSU technology and the requirements of typical business scenarios,this paper proposes an OSU management and control architecture and a management and control interface functional architecture,and elaborates the implementation principle of north-south interface and the verification scheme of the management and control function,which provides management and control technology support for OSU technology to be applied in the current network of typical business scenarios of optical network.
