Minutes from IETF95

Hello BMWG,
	First, a huge thanks to Marius who took pristine notes for us at IETF95. This is in addition to being remote,
where just being remote can be the hindrance. Thank you Marius!
	Please find the minutes from IETF95 here: https://www.ietf.org/proceedings/95/minutes/minutes-95-bmwg
	Please send me any errata or comments or questions you have.

Hi Bhuvan,


I was wondering if defining more precisely what DoS attacks mean makes sense. Although there are several DoS attack types, based in the document content I assume it is referring to volumetric attacks, so it could be useful to include this clarification in the “term” draft.


Additionally, if my previous assumption is true, I was also wondering if having a clear baseline or values related to DoS attacks can help (basically would allow running different tests consistently and avoid misinterpretations). Since the increased amount of requests (packets/traffic/sessions/etc.) is the typical behavior of the volumetric DoS attacks, in the “meth” draft you could include some value in order to define when you are considering that a certain volume of these requests mean a volumetric DoS attack is ongoing.


Probably giving just one fixed value can be difficult because it will vary from one controller to another (in fact depending of their performance). But perhaps a table including a list/group of them or even some relative values based in what you have already measured about the controller performance in the first part of the procedure can give some kind of curve or ramp about how each value of illegitimate requests affects performance until the controller goes off.

rfc 7747 auth48 changes. - was draft-ietf-bmwg-bgp-basic-convergence-05

It's been a pretty long time on this draft given the misref status.

The final scrub of the document has some significant editorial changes
which the wg should peruse it is here:


differentiation between tcp md5 and tcp ao being an important and
siginficant change.

I-D Action: draft-ietf-bmwg-ipv6-nd-02.txt

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

        Title           : Benchmarking IPv6 Neighbor Cache Behavior
        Authors         : William Cerveny
                          Ron Bonica
	Filename        : draft-ietf-bmwg-ipv6-nd-02.txt
	Pages           : 10
	Date            : 2016-04-05

   This document is a benchmarking instantiation of RFC 6583:
   "Operational Neighbor Discovery Problems" [RFC6583].  It describes a
   general testing procedure and measurements that can be performed to
   evaluate how the problems described in RFC 6583 may impact the
   functionality or performance of intermediate nodes.

The IETF datatracker status page for this draft is:

There's also a htmlized version available at:

A diff from the previous version is available at:

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.

Remote participation


During IETF-95, it's possible to participate remotely
using Meetecho and ask questions in a virtual queue.
However, the usual remote features, jabber and audio
will continue to be available.

To use Meetecho, you must register as a remote participant
(free) and below is the link for that operation:


Bear with us as we navigate this new meeting feature.

Hello BWWG,
According to the minutes from IETF94 (https://www.ietf.org/proceedings/94/minutes/minutes-94-bmwg), those present in the room expressed interest in the draft. There've been several reviewers, and strong discussion during each IETF meeting since the draft was introduced. As Al is a named author, I'd like to, with my chair hat on, ask the BMWG list to confirm their support for this draft and call for adoption. 

Please reply with your opinion whether the BMWG should adopt this draft, whether you have read the draft, and any comments on the draft or this call for adoption. Let's attempt to complete this call for adoption and meet a deadline of April 20th, 2016.

Kind regards,
BMWG Co-Chair

Request for your comments on SDN Controller Benchmarking Drafts

Dear BMWG & SDNRG members,


Thank you very much for providing your valuable comments and support for this work. We have updated the draft about SDN Controller benchmarking addressing comments received in the mailing list. The latest drafts can be found here:





Summary of Changes – Terminology Document:

1.       Removed a few terminologies ( e.g., SDN Nodes etc.,) that are already defined in RFC 7426 and added references for that RFC. The is based on feedback from Al Morton, Adrian and Mohamed Boucadair

2.       Added test setup information based on Scott’s feedback


Summary of Changes – Methodology Document:

1.           Added requirements for Test Emulator and added some texts for test repeatability. This is based on feedback from Scott, Al and Doug Montgomery.


### We are still considering a solution for comments received from Marius G about summarizing test results in terms of Average vs Median .


We would love to hear any further comments/queries on these drafts.
