Abstract Abstract
The purpose of this informational document is to establish definitions The purpose of this informational document is to establish definitions
and describe measurement techniques for data center benchmarking, as and describe measurement techniques for data center benchmarking, as
well as it is to introduce new terminologies applicable to performance well as it is to introduce new terminologies applicable to performance
evaluations of data center network equipment. This document establishes evaluations of data center network equipment. This document establishes
