A method of end to end demarcation for video business based on xDR record

视频业务正逐步成为运营商最重要的业务之一.为了保证用户视频业务感知,快速有效地进行端到端问题定界定位,是十分必要的.提出了一种基于话单的视频业务端到端问题定界方法,能够基于应用层HTTP与传输层TCP,结合视频业务特征,全方位分析发送接收窗口、分组特征、传输时延,创新采用上下游二分定界和聚类精确定界,端到端定界导致视频质差的劣化节点.

Video business is gradually becoming one of the most important business of telecom operators.In order to ensure users’perception of video services,it is very necessary to quickly and effectively locate end-to-end problems.A new method of end to end demarcation for video service based on billed list Was proposed,which could be based on the application layer HTTP protocol and transmission layer TCP protoc01.combined with the video service features,to analyze the sending and receiving windows,packet features and transmission delays,etc.Innovating the upstream and downstream binary algorithm,end to end demarcation poor video quality.
