Advanced Stream and Sampling Framework for IP Performance Metrics
RFC 7312, “Advanced Stream and Sampling Framework for IP Performance Metrics”, is an Informational document published in August 2014 by J. Fabini, A. Morton. It updates RFC 2330. The canonical text is published by the RFC Editor.
Abstract
To obtain repeatable results in modern networks, test descriptions need an expanded stream parameter framework that also augments aspects specified as Type-P for test packets. This memo updates the IP Performance Metrics (IPPM) Framework, RFC 2330, with advanced considerations for measurement methodology and testing. The existing framework mostly assumes deterministic connectivity, and that a single test stream will represent the characteristics of the path when it is aggregated with other flows. Networks have evolved and test stream descriptions must evolve with them; otherwise, unexpected network features may dominate the measured performance. This memo describes new stream parameters for both network characterization and support of application design using IPPM metrics.
