Data Center Benchmarking Terminology
Abstract
The purposes of this informational document are to establish
definitions and describe measurement techniques for data center
benchmarking, as well as to introduce new terminology 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 prerequisite for the
test methodology document (RFC 8239). Many of these terms and
methods may be applicable to network equipment beyond the scope of
this document as the technologies originally applied in the data
center are deployed elsewhere.
