OTN运力图绘制展示研究和应用

Research and application of OTN transmission capacity map drawing and display

提出以网络设备机房为端点,以OTN链路为线条,在算网大脑上简洁清晰地呈现OTN算力网络拓扑和运力信息。算网大脑通过SDN网络控制器获取OTN网络的拓扑信息,通过资源管理系统获取OTN网元GIS信息,对网络拓扑赋予经纬度信息并在地图上直观呈现。OTN运力图为运营商运营人员提供了地理化可视的监控工具,便于对OTN链路的时延、带宽、利用率等网络性能指标和链路状态的了解,同时也为算力网络的规划设计、算力灵活调度提供了直观准确的数据参考。

This paper proposes to use the room as the endpoint and the OTN link as the line to present the OTN computing first network topology and network transmission capacity information concisely and clearly on the intelligent operation center.The intelligent operation center for computing first network obtains the topology information of the OTN network through the SDN network controller,obtains the GIS information of the OTN network elements through the resource management system,and presents the network topology with geographical location information on the map.The OTN network transmission capacity map provides performance monitoring tools for the network operation and maintenance engineer,which facilitates the monitoring of network performance indicators such as time-delay,bandwidth,and utilization of OTN links and link status,and also provides accurate&intuitive information for the planning and design of the computing first network and flexible scheduling of computing power.
