draft-ietf-bmwg-b2b-frame-01
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 November 2019
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]. In particular, analysis of the
results indicates that buffers size matters when compensating for
disruptions in the software packet processor, and this finding
