IMIX Genome: Specification of variable packet sizes for additional
testing
draft-ietf-bmwg-imix-genome-04
Abstract
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
specification.
