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 “-02”
draft and reviewed the changes which constitute “-03” and “-04”.
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.
