              Methodology for VNF Benchmarking Automation
                      draft-rosa-bmwg-vnfbench-02

Abstract

   This document describes a common methodology for automated
   benchmarking of Virtualized Network Functions (VNFs) executed on
   general-purpose hardware.  Specific cases of benchmarking
   methodologies for particular VNFs can be derived from this document.
   Two open source reference implementations are reported as running
   code embodiments of the proposed, automated benchmarking methodology.

1.  Introduction

   Benchmarking Methodology Working Group (BMWG) initiated efforts,
   approaching considerations in [RFC8172], to develop methodologies for
   benchmarking VNFs.  Similarly described in [RFC8172], VNF benchmark
   motivating aspects define: (i) pre-deployment infrastructure
   dimensioning to realize associated VNF performance profiles; (ii)
