Abstract
This document discusses and defines a number of tests that may be
used to describe the performance characteristics of ATM (Asynchronous
Transfer Mode) based switching devices. In addition to defining the
tests this document also describes specific formats for reporting the
results of the tests.
This memo is a product of the Benchmarking Methodology Working Group
(BMWG) of the Internet Engineering Task Force (IETF).
