                  Data Center Benchmarking Terminology
                 draft-ietf-bmwg-dcbench-terminology-02

Abstract

The purpose of this informational document is to establish definitions,
discussion and measurement techniques for data center benchmarking.
Also, it is to introduce new terminologies applicable to data center
performance evaluations. The purpose of this document is not to define
the test methodology, but rather establish the important concepts when
one is interested in benchmarking network switches and routers in the
data center.
