Terminology for Benchmarking Session Initiation Protocol (SIP) Devices:
                  Basic Session Setup and Registration

Abstract

   This document provides a terminology for benchmarking the Session
   Initiation Protocol (SIP) performance of devices.  Methodology
   related to benchmarking SIP devices is described in the companion
   methodology document (RFC 7502).  Using these two documents,
   benchmarks can be obtained and compared for different types of
   devices such as SIP Proxy Servers, Registrars, and Session Border
   Controllers.  The term "performance" in this context means the
   capacity of the Device Under Test (DUT) to process SIP messages.
   Media streams are used only to study how they impact the signaling
   behavior.  The intent of the two documents is to provide a normalized
   set of tests that will enable an objective comparison of the capacity
   of SIP devices.  Test setup parameters and a methodology are
   necessary because SIP allows a wide range of configurations and
   operational conditions that can influence performance benchmark
   measurements.  A standard terminology and methodology will ensure
   that benchmarks have consistent definitions and were obtained
   following the same procedures.
