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.
