The IESG has approved the following document: - 'Terminology for Benchmarking Session Initiation Protocol (SIP) Devices: Basic session setup and registration' (draft-ietf-bmwg-sip-bench-term-12.txt) as Informational RFC This document is the product of the Benchmarking Methodology Working Group. The IESG contact persons are Joel Jaeggli and Benoit Claise. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-bmwg-sip-bench-term/ Technical Summary All networking devices have a limited capacity to serve their purpose. In some cases these limits can be ascertained by counting physical features (e.g., interface card slots), but in other cases standardized tests are required to be sure that all vendors count their protocol-handling capacity in the same way, to avoid specmanship. This draft addresses one such case, where the SIP session-serving capacity of a device can only be discovered and rigorously compared with other devices through isolated laboratory testing. This document describes the methodology for benchmarking Session -or- This document describes the terminology for benchmarking Session Initiation Protocol (SIP) performance as described in SIP benchmarking terminology document. The methodology and terminology are to be used for benchmarking signaling plane performance with varying signaling and media load. Both scale and establishment rate are measured by signaling plane performance. The SIP Devices to be benchmarked may be a single device under test or a system under test. Benchmarks can be obtained and compared for different types of devices such as SIP Proxy Server, Session Border Controller, and server paired with a media relay or Firewall/NAT device. Working Group Summary There were periods of intense and constructive feedback on this draft, but also several pauses in progress during development. The most lively discussions were prompted by presentation of actual test results using the draft methods, which require significant time investment but are well- worth the result. These drafts serve a useful purpose for the industry. Document Quality There are existing implementations of the method, as noted above. Dale Worley conducted an early review, following BMWG's request of the RAI area. Dales's comments were addressed in version 05. Henning Schulzrinne commented on the original work proposal. Personnel Al Morton is Shepherd, Joel Jaeggli is Responsible AD.
