The IESG has approved the following document: - 'Advanced Stream and Sampling Framework for IPPM' (draft-ietf-ippm-2330-update-05.txt) as Informational RFC This document is the product of the IP Performance Metrics Working Group. The IESG contact persons are Spencer Dawkins and Martin Stiemerling. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ippm-2330-update/ Technical Summary 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. Working Group Summary This draft was first introduced to the working group in October 2012. Support for the draft was indicated at meetings with no dissent. Document Quality As an update to the IPPM Framework, this document adds new and updated considerations for stream parameters. The document shepherd reviewed the document as a â??-02â?? draft and reviewed the changes which constitute â??-03â?? and â??-04â??. As documented, other topics in the IPPM Framework which might be updated or augmented are deferred to future work. This includes the topics of passive and various forms of of hybrid active/passive measurements. Personnel The document shepherd was Bill Cerveny. The responsible area director is Spencer Dawkins.
