1.3. Administrivia

It was noted that the primary goal for the meeting was to review
work plans for the IAB architecture topics identified at the

1.4. Meeting Minutes

The IAB approved minutes from the 2008-01-16 meeting.

2. Action Item Status

In order to maximize time for architecture topics only notable
action item and document status updates were discussed rather
than the usual review of all items. Olaf stated that there was a
status change for the Infrastructure ENUM document – the last call
has gone out and been responded to, and there is a draft liaison
statement that will be finalized after last call.

3. Document Status

Dave Thaler asked when the email would go out to publish the
protocol success document, and Olaf responded that it would occur
this week. Dave then commented that Bernard had posted the changes
to the IP host configuration draft, and that it was ready for
further review by the IAB.

4. Architecture Topics – Work Plan Review

Olaf noted that there had been little progress on the architecture
topics in the last week, with the exception of the P2P topic.
Gonzalo added material on P2P to the internal IAB wiki, but was not
available for the call today. Dow suggested the group could review
Dave Thaler’s material on the Evolution of the IP Model, and the
group then decided to do so.

4.1. Evolution of the IP Model

Dave Thaler led a discussion on the Evolution of the IP Model,
walking through a work plan he had posted to the IAB wiki. The
overall goal of the proposed document would be to assemble the list
of common assumptions that higher layers make about the network
layer, and then provide guidance on the impacts of changing these
assumptions. The IAB will then attempt to give guidance on which
assumptions are good to restore, as well as which assumptions are
either no longer valid or unlikely / unable to be restored.

At the IAB retreat Dave had discussed a list of possible IAB
actions in this area (e.g. document, workshop, techchat), and it
now appears that the document will be be the primary work item.
The group also briefly discussed the possibility of scheduling the
topic as an IETF plenary presentation once the work matures.
There is an upcoming seminar hosted by Lars Eggert that has
participants from the research community, and Dave intends to give
an introductory presentation on the topic at that meeting. This
seminar should be a good opportunity to get some initial ideas and
feedback from outside the IAB.

The rest of the IAB was requested to provide examples of IP Model
assumptions, which Dave will collect and then work with the
contributors to draft an initial document. A technical discussion
followed of areas of IETF work where there are potential collisions
between lower and upper layers, areas that might be aided by this
type of IAB document (e.g. ID/LOC split).

At the close of this agenda item the other topic leads were asked
to prepare similar material for their topics by the next IAB

4.2. Firewalls and IPv6

(no further discussion)

4.3. Securing Inter-domain Routing

(no further discussion)

4.4. Peer-to-Peer Architectures

(no further discussion)

4.5. User Control of Traffic

(no further discussion)


5. Liaison Discussion

At this point in the meeting the board entered an executive session
to discuss Liaisons to ISO TC46 and 802.1.

5.1. Liaison to TC46

The TC46 liaison would be a new IETF relationship with ISO, and the
IAB decided on John Klensin for that liaison role.

5.2. Liaison to 802.1

The current 802.1 liaison, Bert Wijnen, has indicated that he
intends to resign from the position once a replacement can be found.
Loa took an action to contact the relevant working groups and
develop a list of potential candidates.

6. AOB

Olaf gave a brief update on recent conversations with IANA and DoC
staff on plans to deploy DNSSEC, and to sign the .arpa and root
