Methodology for VNF Benchmarking Automation
draft-rosa-bmwg-vnfbench-03
Abstract
This document describes a common methodology for the 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.
