I-D ACTION:draft-ietf-bmwg-ospfconv-applicability-05.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Benchmarking Methodology Working Group of the IETF.

	Title		: Benchmarking Applicability for Basic OSPF Convergence
	Author(s)	: V. Manral, et al.
	Filename	: draft-ietf-bmwg-ospfconv-applicability-05.txt
	Pages		: 11
	Date		: 2004-6-1
	
   This document discusses the applicability of various tests for
   measuring single router control plane convergence, specifically in
   regards to the Open Shortest First (OSPF) protocol. There are two
   general sections in this document, the first discussing specific
   advantages and limitations of specific OSPF convergence tests, and
   the second discussing more general pitfalls to be considered when
   testing routing protocols convergence testing.

I-D ACTION:draft-ietf-bmwg-ospfconv-term-08.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Benchmarking Methodology Working Group of the IETF.

	Title		: OSPF Benchmarking Terminology and Concepts
	Author(s)	: V. Manral, et al.
	Filename	: draft-ietf-bmwg-ospfconv-term-08.txt
	Pages		: 9
	Date		: 2004-6-1
	
   This draft explains the terminology and concepts used in OSPF
   benchmarking. While some of these terms may be defined elsewhere, and
   we will refer the reader to those definitions in some cases, we also
   include discussions concerning these terms as they relate
   specifically to the tasks involved in benchmarking the OSPF protocol.

Re: BMWG Last Call: draft-ietf-bmwg-igp-dataplane-conv-***-02

IGP Dataplane-ers,

As a BMWG participant, a few comments on
At 11:50 AM 05/10/2004, somebody named Al Morton wrote:
>BMWG ... Last Call ...
>Terminology for Benchmarking IGP Data Plane Route Convergence
>http://www.ietf.cnri.reston.va.us/internet-drafts/draft-ietf-bmwg-igp-dataplane-conv-term-02.txt

I read Bob Holley's comment that Figure 1 was unclear,
and I wonder if some of the difficulty was related to formatting.
When I print this draft, some of the lines in the figure are
shifted and the sloping lines don't line-up. I know it
looks right on screen, but I suspect tabs or other problem...

Section 3.14 Packet Sampling Interval
The text says rate, but the term is an inter-polling interval,
the reciprocal of rate.

To illustrate, this or similar wording would be OK with me:

Definition: The time interval for counting packet arrivals, possibly
to determine the Forwarding Rate. For example, the interval between
readings of a packet counter.

A few comments on the Methodology, again as a participant:

Though the figures printed just fine in the version-01,
they all suffer the same miss-alignment I mentioned in
the term memo comments.

On section 3.2.4, we had the following discussion (7/9/04):

Authors Action Items to Comments for draft-ietf-bmwg-igp-datapla ne-conv-***-02

BMWG-ers,

Thanks very much to Brooks Hickman and  Robert Holley for their thorough
reviews of the Terminology document and to Tanju Cataltepe and Al Morton for
their thorough reviews of the Terminology and Methodology documents.  For
the sake of all BMWG participants I have consolidated and paraphrased their
comments for review.  Please let me know if you have additional or follow-up
comments.  The changes agreed to below will be submitted in 03 revisions
prior to the deadline for San Diego.  In addition, Bob Holley made further
comments that I will address in a separate email to follow shortly.

Scott

RE: Authors Action Items to Comments for draft-ietf-bmwg-i gp-datapla ne-conv-***-02

Robert,

Please find the following responses to additional comments you had made.
Follow-up comments from other BMWG participants is also welcome.

Scott
########################

1. In several sections the convergence state is
defined by the "forwarding rate" equal to the
"offered load". May be better to clarify that
the offered load must be less than or equal to the
capacity of the device.

RESPONSE - Forwarding Rate is an IETF (BMWG) defined term for an interface.

2.  Section 3.3 Route Convergence
This term seems misleading. The definition
implies the convergence of the routing function
on a single device. But "route convergence" implies
a source-destination path (e.g. multiple devices).

RESPONSE - The intention of this work item is to define terms and
methodologies for benchmarking convergence for a single routing device.  The
terms 'Route Convergence' and 'Network Convergence' are defined within this
work item.

3. Section 3.4 Full Convergence
The term "converge an entire route table" to
me implies completion of an algorithm.

Document Action: 'Methodology for IP Multicast Benchmarking' to Informational RFC

The IESG has approved the following document:

- 'Methodology for IP Multicast Benchmarking '
   <draft-ietf-bmwg-mcastm-14.txt> as an Informational RFC

This document is the product of the Benchmarking Methodology Working Group. 

The IESG contact persons are Bert Wijnen and David Kessens.

Technical Summary

 This document describes methodology specific to the benchmarking
 of multicast IP forwarding devices. It builds upon the tenets set
 forth in RFC 2544, RFC 2432 and other IETF Benchmarking Methodology
 Working Group (BMWG) efforts.  This document seeks to extend these
 efforts to the multicast paradigm.

Working Group Summary

 After many WG last calls, the WG has consensus on publishing this
 document

Protocol Quality

 Bert Wijnen has reviewed this document for the IESG, and so has 
 David Meyer.

RFC-Editor notes:

- On page 3, pls add another (last) para to section 1:

I-D ACTION:draft-ietf-bmwg-ospfconv-intraarea-09.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Benchmarking Methodology Working Group of the IETF.

	Title		: Benchmarking Basic OPSF Single Router Control 
			  Plane Convergence
	Author(s)	: V. Manral, et al.
	Filename	: draft-ietf-bmwg-ospfconv-intraarea-09.txt
	Pages		: 16
	Date		: 2004-6-29
	
This draft establishes standards for measuring OSPF single router
control plane convergence [TERM]. Its initial emphasis is on the
control plane of single OSPF routers.  We do not address forwarding
plane performance.
NOTE: Within this document, the word convergence relates to single
router control plane convergence only.
