                 draft-ietf-bmwg-dcbench-terminology-19

Abstract

The purpose of this informational document is to establish definitions
and describe measurement techniques for data center benchmarking, as
well as it is to introduce new terminologies applicable to performance
evaluations of data center network equipment. This document establishes
the important concepts for benchmarking network switches and routers in
the data center and, is a pre-requisite to the test methodology
publication [draft-ietf-bmwg-dcbench-methodology]. Many of these terms
and methods may be applicable to network equipment beyond this
publication's scope as the technologies originally applied in the data
center are deployed elsewhere.
