Minutes of the IP Address Encapsulation BOF (IPAE)

The IP Address Encapsulation BOF was a 3-hour session on Thursday
morning, July 9th.  Approximately 100 people attended.

Bob Hinden gave a summary presentation of the goals and approach for
solving the IP address-space limitation problem by use of an
encapsulation technique which adds fields for new, globally unique
addresses in a mini-layer above IP but below transport.  A technical
proposal was previously submitted as an Internet Draft
(draft-crocker-ip-encaps-00.txt) and copies were provided.  The handouts
also included an initial assessment of implementation issues for BSD
Unix, by Craig Partridge.

A key point in the questioning was the absence of a detailed proposal
for the specific addressing scheme to be used.  The current IPAE
proposal constrains the last 4 octets of the larger, global addresses to
be old-style IP addresses, but no other constraints or details were
provided.  While this was intentional, it was clear that the audience
desired to have a concrete proposal.  A separate effort to develop an
addressing proposal has since begun as a sub-effort of the IPAE team.

The IPAE approach has as its main operational goal to limit impact on
the installed base.  It does this by defining the Internet to comprise a
set of addressing ``commonwealths'' each with its own 32-bit address
space.  Within a commonwealth, classic IP always will be used.  So,
routers within the commonwealth and hosts which need to communicate only
within that commonwealth will be able to conduct their business using
old-style IP and require no change.

It was observed that this can turn segments of the Internet into
isolated ``islands''.  However, such islands are already part of the
operational Internet, since some organizations operate that way for
security purposes.  Further, only hosts need to upgrade.  It is intended
that interior routers will not need to.

The BOF was intended to test the waters for forming a working group, as
well as report on work-to-date.  It was generally agreed that the
working group should be formed.  It intends to develop a complete
specification for the core changes, a complete specification for an
addressing scheme, and a specification of the procedures and mechanisms
that will be needed to permit transition and coexistence for IP and
IPAE.
