1.3. Administrivia

1.4. Meeting Minutes

No meeting minutes were reviewed during this call.

2. IETF 74 Plenary

Andy reported that three speakers have been confirmed for the panel on MPLS, and that slides will be submitted for IAB review within a few weeks. Andy also requested that IAB members think of some good questions for the speakers and send them to him for consolidation.

3. NAT 66

The group engaged in nearly an hour-long discussion of NAT66, led by Dave Thaler and Lixia Zhang. After a recap of the previous NAT66 discussions, particularly the issue of address renumbering, the key question involving end-to-end transparency was raised. “Is translation a part of the IPv6 architecture or not?” That is, do all the components in the IPv6 internet need to accommodate translation, or is it the requirement of the site conducting such translation to do so in a manner that is transparent to outside entities? It was noted that there are different kinds of translation available depending on the particular nature of the problem that NAT is attempting to solve. Without knowing the type it is difficult to assess whether translation should be part of the architecture.

Dave Thaler once again asked the open question of whether PI space is a viable answer – that is, following a path that allows for anyone experiencing renumbering pain to obtain and use PI space. There was no immediate consensus on the answer to this question.

Dave Thaler and Lixia Zhang will organize a follow-up discussion on the topic for the Sunday afternoon meeting at IETF. The board will attempt to submit a draft on the topic ahead of the draft -00 cutoff date.
