摘　　要：算网大脑通过向OTN控制器查询,获取以指定机房为中心,小于等于指定时延指标的所有机房节点的信息。基于这些节点的地理位置信息,算网大脑用Graham扫描算法生成凸多边形,进而通过调用能力开放平台平滑接口计算生成平滑面,在GIS地图上绘制和展示每个网络机房或算力机房的时延圈。通过这种方法,将运营商的OTN网络时延性能进行地理化呈现,便于客户快速直观地选云、入云,同时也能协助运营商在规划算力机房时选择最佳的地理位置,以满足目标区域的算力服务覆盖需求。The computing&network brain queries the OTN controller to obtain the information of all computer rooms,with the requirement that a specified computer room as the center and the time-delay less than or equal to a specified range.The Graham scanning algorithm is used to generate convex polygons based on the location information of these rooms,and then calculate the smooth surface through the smooth interface of the capability open platform,then the delay circle of the network room or the computing room is plotted and displayed on the GIS map.Through this method,the OTN network delay performance of operators is geographically present,which is convenient for customers to quickly and intuitively select the right cloud to provide service,and also can help operators to select the best geographical location when planning the computing room,so as to meet the demand for computing service coverage in the target area.
