METHODS AND APPARATUS FOR IDENTIFYING CHRONIC PERFORMANCE PROBLEMS ON DATA NETWORKS |
摘要 |
A system for identifying chronic performance problems on data networks includes network monitoring devices that provide measurements of performance metrics such as latency, fitter, and throughput, and a processing system for analyzing measurement data to identify the onset of chronic performance problems. Network behavior is analyzed to develop a baseline performance level (e.g., computing a mean and variance of a baseline sample of performance metric measurements). An operating performance level i s measured during operation of the network (e.g., computing a mean and variance of an operating sample of performance metric measurements). A chronic performance problem is identified if the operating performance level exceeds a performance threshold and a difference between the baseline performance level and the operating performance level is determined to be statistically significant. A t-test based on the baseline mean and variance and the operating mean and variance can be used to determine if this difference is significant .
