IMIX Genome: Specification of Variable Packet Sizes for Additional Testing
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 a constant packet size
reveal device capabilities but differ significantly from the
conditions encountered in operational deployment, so additional tests
are sometimes conducted with a mixture of packet sizes, or "IMIX"
("Internet Mix"). 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 document defines a way to specify the exact
repeating sequence of packet sizes from the usual set of fixed sizes
and from other forms of mixed-size specification.
