Abstract

This document discusses and defines a number of tests that may be used to describe the performance characteristics of a network interconnecting device. In addition to defining the tests this document also describes specific formats for reporting the results of the tests. Appendix A lists the tests and conditions that we believe should be included for specific cases and gives additional information about testing practices. Appendix B is a reference listing of maximum frame rates to be used with specific frame sizes on various media and Appendix C gives some examples of frame formats to be used in testing.

1. Introduction

Vendors often engage in "specsmanship" in an attempt to give their products a better position in the marketplace. This often involves "smoke & mirrors" to confuse the potential users of the products.

This document defines a specific set of tests that vendors can use to measure and report the performance characteristics of network devices. The results of these tests will provide the user comparable data from different vendors with which to evaluate these devices.

A previous document, "Benchmarking Terminology for Network Interconnect Devices" (RFC 1242), 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.

2. Real world

In producing this document the authors attempted to keep in mind the requirement that apparatus to perform the described tests must actually be built. We do not know of "off the shelf" equipment available to implement all of the tests but it is our opinion that such equipment can be constructed.

3. Tests to be run

There are a number of tests described in this document. Not all of the tests apply to all types of devices under test (DUTs). Vendors should perform all of the tests that can be supported by a specific type of product. The authors understand that it will take a considerable period of time to perform all of the recommended tests nder all of the recommended conditions. We believe that the results are worth the effort. Appendix A lists some of the tests and conditions that we believe should be included for specific cases.

4. Evaluating the results

Performing all of the recommended tests will result in a great deal of data. Much of this data will not apply to the evaluation of the devices under each circumstance. For example, the rate at which a router forwards IPX frames will be of little use in selecting a router for an environment that does not (and...
