        Updates for the Back-to-back Frame Benchmark in RFC 2544
                     draft-morton-bmwg-b2b-frame-03

Abstract

   Fundamental Benchmarking Methodologies for Network Interconnect
   Devices of interest to the IETF are defined in RFC 2544.  This memo
   updates the procedures of the test to measure the Back-to-back frames
   Benchmark of RFC 2544, based on further experience.

   This memo updates Section 26.4 of RFC 2544.

1.  Introduction

   The IETF's fundamental Benchmarking Methodologies are defined
   in[RFC2544], supported by the terms and definitions in [RFC1242], and
   [RFC2544] actually obsoletes an earlier specification, [RFC1944].
   Over time, the benchmarking community has updated [RFC2544] several
   times, including the Device Reset Benchmark [RFC6201], and the
   important Applicability Statement [RFC6815] concerning use outside
   the Isolated Test Environment (ITE) required for accurate
   benchmarking.  Other specifications implicitly update [RFC2544], such
   as the IPv6 Benchmarking Methodologies in [RFC5180].

Internet-Draft              B2B Frame Update                October 2018

   Recent testing experience with the Back-to-back Frame test and
   Benchmark in Section 26.4 of [RFC2544] indicates that an update is
   warranted [OPNFV-2017] [VSPERF-b2b].  This memo describes the
   rationale and provides the updated method.

   [RFC2544] provides its own Requirements Language consistent with
   [RFC2119], since [RFC1944] predates [RFC2119].  Thus, the
