Network performance root-cause analysis

Abstract

A data-driven approach to network performance diagnosis and root-cause analysis is presented. By collecting and aggregating data attribute values across multiple components of a content delivery system and comparing against baselines for points of inspection, network performance diagnosis and root-cause analysis may be prioritized based on impact on content delivery. Alerts may be generated to present recommended courses of action based on the tracked performance analysis.

What is claimed is: 
     
         1 . A method of operation of a network performance analyzer, comprising:
 selecting an inspection point among a plurality of inspection points in a content delivery system based on an impact upon a particular application program;   aggregating data received from one or more user device agents and one or more proxy servers related to the inspection point, the one or more proxy servers communicate user device data requests to one or more server components of the content delivery system;   analyzing the aggregated data in order to detect anomalies associated with the inspection point;   tracking anomalies associated with the inspection point;   determining an impact that an anomaly has on performance of the content delivery system;   generating a recommendation to improve a portion of the content delivery system that improves overall network performance as perceived by network users based on the determined impact.
