              Methodology for VNF Benchmarking Automation
                      draft-rosa-bmwg-vnfbench-06

Abstract

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