Advanced Stream and Sampling Framework for IP Performance Metrics (IPPM)
Joachim Fabini, Al Morton · 2014
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.
