RFC 2889 LAN Switch Benchmarking Methodology August 2000

1. Introduction

This document is intended to provide methodology for the benchmarking of local area network (LAN) switching devices. It extends the methodology already defined for benchmarking network interconnecting devices in RFC 2544 [3] to switching devices.

This RFC primarily deals with devices which switch frames at the Medium Access Control (MAC) layer. It provides a methodology for benchmarking switching devices, forwarding performance, congestion control, latency, address handling and filtering. In addition to defining the tests, this document also describes specific formats for reporting the results of the tests.

A previous document, "Benchmarking Terminology for LAN Switching Devices" [2], defined many of the terms that are used in this document. The terminology document SHOULD be consulted before attempting to make use of this document.
