Methodology for Benchmarking Session Initiation Protocol (SIP) Devices: Basic Session Setup and Registration
draft-ietf-bmwg-sip-bench-meth-12

[Ballot comment]
It seems like it might be worth noting for the media-on-DUT cases that the degree of SIP performance degradation due to media might differ depending on factors like what the DUT does with the media (e.g., relaying vs. transcoding), the type of media (audio vs. video vs. data), and the codec used for the media.  There may also be cases where there is no performance impact, if the DUT has dedicated media-path hardware.

[Ballot comment]
= Section 4.1 =
"It is best
            ; off to start with the defaults (w = 0.10 and
            ; r >= 10)"

I thought the default was r = 100?

[Ballot comment]
Since this is a set of benchmarks for use in a lab environment, I agree with the security considerations section statement that there are no considerations when used in the way described.  Thanks.

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the

Abstract


  This document provides a methodology for benchmarking the Session
  Initiation Protocol (SIP) performance of devices.  Terminology
  related to benchmarking SIP devices is described in the companion
  terminology document.  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 configuration and operational conditions that can influence
  performance benchmark measurements.

Al Morton is the Document Shepherd, and prepared this form.

(1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational, Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title page header?

Informational, as indicated on the title page.
All BMWG RFCs are traditionally Informational,
in part because they do not define protocols and
the traditional conditions for Stds track advancement
did not apply.  However, they are specifications and
the RFC 2119 terms are applicable to identify the
level of requirements.

(2) The IESG approval announcement includes a Document Announcement Write-Up. Please provide such a Document Announcement Write-Up. Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections:

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 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:

Who is the Document Shepherd? Who is the Responsible Area Director?
Al Morton is Shepherd, Joel Jaeggli is Responsible AD.

(3) Briefly describe the review of this document that was performed by the Document Shepherd. If this version of the document is not ready for publication, please explain why the document is being forwarded to the IESG.

The shepherd has reviewed the drafts many times, and his comments are
in the BMWG archive.

(4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed?
No.

(5) Do portions of the document need review from a particular or from broader perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or internationalization? If so, describe the review that took place.

No. Cross-area review has been obtained, however it impossible to get
the attention of everyone who considers themselves a SIP expert.

(6) Describe any specific concerns or issues that the Document Shepherd has with this document that the Responsible Area Director and/or the IESG should be aware of? For example, perhaps he or she is uncomfortable with certain parts of the document, or has concerns whether there really is a need for it. In any event, if the WG has discussed those issues and has indicated that it still wishes to advance the document, detail those concerns here.

No concerns, this is still a valuable memo, as mentioned above.

(7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why?

There are not outstanding IPR disclosures, according to the authors.

(8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures.

No.

(9) How solid is the WG consensus behind this document? Does it represent the strong concurrence of a few individuals, with others being silent, or does the WG as a whole understand and agree with it?

Although the comments and review intensity was highly variable,
it now appears that the WG is satisfied. 
The first WGLC was completed on 5 April 2010 with comments.
The second WGLC was completed on 18 May 2012 with comments.
The third WGLC was completed on 10 Dec 2012 with comments, and the 1st Pub Request.

No.

(11) Identify any ID nits the Document Shepherd has found in this document. (See http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). Boilerplate checks are not enough; this check needs to be thorough.

No.

(16) Will publication of this document change the status of any existing RFCs? Are those RFCs listed on the title page header, listed in the abstract, and discussed in the introduction? If the RFCs are not listed in the Abstract and Introduction, explain why, and point to the part of the document where the relationship of this document to the other RFCs is discussed. If this information is not in the document, explain why the WG considers it unnecessary.

No.
