Approaches to Measurement Aggregation Store all the singletons of the Measurement Intervals Evaluate all singletons in the Reporting Interval Methods like those envisioned in "Framework for Metric Composition", draft-ietf-ippm-framework-compagg-05, for Temporal Aggregation Produce an estimate of the metric for the Reporting Interval using a deterministic process to combine the metrics from measurement intervals. Use a numerical objective for the metric, and compare the results of each measurement interval: Every measurement interval where the results meet the objective contribute to the fraction of time with performance as specified. Present the results as "metric A was less than or equal to objective X during Y% of time. |
