CAPACITY PLANNING ANALYSES OF LARGE DATA NETWORKS: A CASE STUDY

摘要

Forecasting the performance of a Local Area Network or Wide Area Network has been difficult due to extremely large variances in utilization. Large numbers of network devices can compound the difficulty. An aggregation technique that takes into account the historical utilization of these devices is examined, and the reliability of forecasts based on them is discussed. The accuracy of trending the highest weekly hourly averages for aggregations of devices versus individual network devices is presented. A strategy for reducing the choice of metrics to track for each resource is also discussed as an alternative to the exhaustive measurement of each resource and device.
