IPng Requirements BOF (NGREQS)

Reported by Jon Crowcroft/University College London

The IPNG Requirements BOF met on the morning of 31 March 1994.  The goal
of the meeting was to review the ``Technical Criteria for Choosing
IP:The Next Generation (IPng)'' Internet-Draft
(draft-kastenholz-ipng-criteria-01.txt).

The meeting was broken into two parts, short presentations by several
experts in particular technologies, followed by a general discussion.

The technical presentation part of the discussion lasted for about one
hour.  Several people gave brief, three minute, presentations on the
requirements that their own particular technology had on IPng.  This was
very similar to the White Paper process used by the IPng Directorate,
though much less formal.  A brief open discussion also followed each
presentation.


Network-layer Security


Mike St. Johns gave a brief presentation on network-layer security.  He
described the functions that would be needed in order to properly secure
the network layer.  Among them:  privacy and authentication of packets,
key distribution, and access and resource control.

In the open discussion, the group expressed its sentiments that security
must be present in IPng and that the requirements should be worded as
strongly as possible.


Mobility


Greg Minshall gave a talk about mobility.  Several points that he
brought out were that firewalls are bad for mobility, the control
protocol (ICMPng) should have large data fields, separate addresses and
end endpoint identifiers are highly desirable, and that router discovery
is necessary.

In the ensuing open discussion two points were brought up:


   o There is a need for larger data areas in ICMPv4 error messages for
     transition and coexistence.

   o The group wants both mobility and portability in IPng.


Network Services

Dave Clark gave a talk about network services.  His points included that
IPng be able to efficiently map packets into services, that there be
security for this class mapping scheme, and that highly sophisticated
routing be available that can do things like select providers, route
according to desired services, and so on.


AVT and MMUSIC Work

Mark Handley gave a brief talk about the AVT and MMUSIC work.  He
indicated that for these areas, low delay and high reliability in the
network were to be particularly favored.  Also, he said that larger MTUs
and smaller headers were desirable.


RSVP

Lixia Zhang talked about RSVP. RSVP's particular concerns were that the
routes be stable and that endpoints be notified if routes change, that
the routing be able to route based on QOS information, and that a
network user must be able to prove that the network is providing the
desired service level.


IPng

Peter Ford gave a brief talk on IPng from the perspective of a network
operator.  The important points that he brought out were that one must
be able to do provider selection, and that the network operators must be
able to control the routing within their networks in order to do things
like load-shedding and balancing, switching to backup routes, and the
like.

John Curran gave a talk indicating that IPng must give end users a
strong incentive to migrate to IPng and leave IPv4.  Simply being able
to deal with larger networks (i.e., larger address spaces) would not be
sufficient.


General Discussion

The group then had a general, open discussion.  Additional points were
raised and discussed.


   o Convergence.  Several members of the group expressed a desire that
     IPng provide for convergence for all protocol families (e.g., OSI,
     NetWare, XNS, and so on).  Some felt that this was just plain
     silly, some felt that this was useful but not a technical
     requirement, and others felt that it was a technical requirement.
     This discussion continued for some time, with no real resolution.

   o The group expressed a desire to have a larger minimum packet size.

   o Address assignment must be delegated as far down the administrative
     hierarchy as possible.

   o Automatic configuration must not preclude manual configuration.

   o It was pointed out that the automatic configuration requirements
     apply only to the internet-layer (analogous to getting the IP
     address and network mask in today's IP). Higher layer configuration
     issues (e.g., registering with the DNS) are important, but are
     explicitly not addressed in the document.

   o A general discussion of architectural issues was held.  This
     discussion was cut off by lack of time.
