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, jitter, 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 is 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.

摘要： A system for measuring peak throughput in packetized data networks includes a remote monitoring probe and console. The probe is connected to a packetized data network to monitor network activity, while the console is in communication with the probe via a communications medium. The probe maintains a plurality of counters associated with different ranges of utilization percentage for access channel and individual circuit bandwidth. For each sampling interval, the probe measures the access channel and individual circuit bandwidth utilization and increments the appropriate counters associated with the percentage ranges encompassing the measured bandwidth utilizations. The console polls the probe for the percentage counter data to selectively display the access channel or individual circuit bandwidth utilization in the form of a bar graph and pie chart. The access channel and/or individual circuit bandwidth may ultimately be adjusted based on the displayed data. Alternatively, the system may analyze the data and determine conservative, moderate and aggressive recommendations for bandwidth adjustment. In addition, the system can generate reports containing the access channel or individual circuit bandwidth utilization for a user-specified time period, and the recommendations for bandwidth adjustment.
