The IESG has approved the following document: - 'IMIX Genome: Specification of variable packet sizes for additional testing' (draft-ietf-bmwg-imix-genome-04.txt) as Informational RFC This document is the product of the Benchmarking Methodology Working Group. The IESG contact persons are Joel Jaeggli and Benoit Claise. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-bmwg-imix-genome/ Technical Summary Benchmarking Methodologies have always relied on test conditions with constant packet sizes, with the goal of understanding what network device capability has been tested. Tests with constant packet size reveal device capabilities but differ significantly from the conditions encountered in operational deployment, and so additional tests are sometimes conducted with a mixture of packet sizes, or "IMIX". The mixture of sizes a networking device will encounter is highly variable and depends on many factors. An IMIX suited for one networking device and deployment will not be appropriate for another. However, the mix of sizes may be known and the tester may be asked to augment the fixed size tests. To address this need, and the perpetual goal of specifying repeatable test conditions, this draft defines a way to specify the exact repeating sequence of packet sizes from the usual set of fixed sizes, and other forms of mixed size Working Group Summary WG Consensus was smooth after development over a reasonable period of time. Document Quality There are many implementations of various test equipment that use IMIX. Personnel Who is the Document Shepherd? Lucien Avramov Who is the Responsible Area Director? Joel Jaeggli
