     Terminology for Benchmarking Software-Defined Networking (SDN)
                         Controller Performance

Abstract

   This document defines terminology for benchmarking a Software-Defined
   Networking (SDN) controller's control-plane performance.  It extends
   the terminology already defined in RFC 7426 for the purpose of
   benchmarking SDN Controllers.  The terms provided in this document
   help to benchmark an SDN Controller's performance independently of
   the controller's supported protocols and/or network services.
