Abstract

   The Benchmarking Methodology Working Group has traditionally
   conducted laboratory characterization of dedicated physical
   implementations of internetworking functions.  This memo investigates
   additional considerations when network functions are virtualized and
   performed in general purpose hardware.

1.  Introduction

   The Benchmarking Methodology Working Group (BMWG) has traditionally
   conducted laboratory characterization of dedicated physical
   implementations of internetworking functions (or physical network
   functions, PNFs).  The Black-box Benchmarks of Throughput, Latency,
   Forwarding Rates and others have served our industry for many years.
   [RFC1242] and [RFC2544] are the cornerstones of the work.

   An emerging set of service provider and vendor development goals is
   to reduce costs while increasing flexibility of network devices, and
   drastically accelerate their deployment.  Network Function
