   This memo discusses and defines terms associated with performance
   benchmarking tests and the results of these tests in the context of
   frame relay switching devices.

I. Background

1. Introduction

   This document provides terminology for Frame Relay switching devices.
   It extends terminology already defined for benchmarking network
   interconnect devices in RFCs 1242, 1944 and 2285.  Although some of
   the definitions in this memo may be applicable to a broader group of
   network interconnect devices, the primary focus of the terminology in
   this memo is on Frame Relay Signaling.

   This memo contains two major sections: Background and Definitions.
   The background section provides the reader with an overview of the
   technology and IETF formalisms.  The definitions section is split
   into two sub-sections.  The formal definitions sub-section is
   provided as a courtesy to the reader.  The measurement definitions
   sub-section contains performance metrics with inherent units.

   The BMWG produces two major classes of documents: Benchmarking
   Terminology documents and Benchmarking Methodology documents.  The
   Terminology documents present the benchmarks and other related terms.
   The Methodology documents define the procedures required to collect
   the benchmarks cited in the corresponding Terminology documents.

RFC 3133        Terminology for Frame Relay Benchmarking       June 2001

   For the purposes of computing several of the metrics, certain textual
   conventions are required.  Specifically:

   1) The notation sum {i=1 to N} A_i denotes: the summation of N
   instances of the observable A.  For example, the set of observations
   {1,2,3,4,5} would yield the result 15.

   2) The notation max {I=1 to N} A_i and min {I=1 to N} A_i denotes:
   the maximum or minimum of the observable A over N instances.  For
   example, given the set of observations {1,2,3,4,5}, max {i=1 to 5} =
   5 and min {I=1 to 5} = 1.

   The terms defined in this memo will be used in addition to terms
   defined in RFCs 1242, 1944 and 2285.  This memo is a product of the
   Benchmarking Methodology Working Group (BMWG) of the Internet
   Engineering Task Force(IETF).

2. Existing Definitions

   RFC 1242, "Benchmarking Terminology for Network Interconnect
   Devices", should be consulted before attempting to make use of this
   document.  RFC 1944, "Benchmarking Methodology for Network
   Interconnect Devices", contains discussions of a number of terms
   relevant to the benchmarking of switching devices and should also be
   consulted.  RFC 2285, "Benchmarking Terminology for LAN Switching
   Devices", contains a number of terms pertaining to traffic
   distributions and datagram interarrival.  For the sake of clarity and
   continuity this RFC adopts the template for definitions set out in
   Section 2 of RFC 1242.

II. Definitions

   The definitions presented in this section have been divided into two
   groups.  The first group is formal definitions, which are required in
   the definitions of the performance metrics but are not themselves
   strictly metrics.  These definitions are subsumed from other work
   done in other working groups both inside and outside the IETF.  They
   are provided as a courtesy to the reader.
