METHOD AND SYSTEM FOR QUANTIFYING EFFECTS OF A CONTENT DELIVERY NETWORK SERVER ON STREAMING-MEDIA QUALITY AND PREDICTING ROOT CAUSE ANALYSIS

Abstract: aspects of the subject disclosure may include, for example, identifying a threshold value of a streaming-media key performance indicator (kpi) based on a predetermined target portion of end-user devices that provide an acceptable performance. performance records are obtained for a content delivery network (cdn) adapted to cache and serve media content requested by the end-user devices. predicted values of the streaming-media kpi are generated according to the performance records of the cdn and compared to the threshold value of the streaming-media kpi to obtain a comparison. an anomaly is detected according to the comparison, to indicate that a predetermined number of the predicted values of the streaming-media kpi fail to satisfy the threshold value. other embodiments are disclosed.
