Hi,

The list name and the name of the archive on world.std.com
have been changed from ipv7 to tpix. The old names work of
course.

This message is more in the way of a test than something you
really needed to know ...

Hi,

The following is the first of several internet drafts to be published
detailing aspects of the TP/IX and RAP protocols not covered in the
base documents.

I am circulating this for initial comments from the group before I
put it up on internet-drafts.

[and while I am bothering you :-]
If you want to test a RAP prototype, *and* you have a public X.25
connection (so we can set up the requisite direct connection to my
lab systems), please contact me.

Best Regards,
Robert

Internet draft          Initial AD Assignment Plan          May 26, 1993


3  Introduction

This memo presents the plan for initial assignments of Administrative
Domain numbers for the Version 7 Internet.  The objective is to use a
very small amount of space in the numbering system, while providing
the necessary distribution of authority.

This plan defines 5/256ths of the number space, while making initial
AD-block assignments covering only 239/65536ths (0.36%) of the code
points available in the most significant 16 bits.

It is important that future plans be equally conservative; in the next
decade no more than 1/25th of the space need be or should be assigned.
Besides the always-unanticipated future expansion, this provides the
space to re-do the numbering plan entirely if it should become
necessary.

It is certainly true that in 10 years, or 25 years, we shall know a
great deal more about what the numbering plan should look like, and it
is prudent to leave as much of the decision as possible to that time.

4  Authority for AD assignments

4.1  IANA

The initial authority for AD assignements is IANA, the Internet
Assigned Numbers Authority (IANA@ISI.EDU).  The IANA will delegate
national blocks with initial octets 120 to 123 in the numbering plan
to national authority when applied for by an appropriate organization.

The initial AD plan also includes specific assignments of blocks with
initial octet 126, for interoperation with existing internetworking
protocols.  Three non-national blocks are delegated in the initial
numbering plan, one (back to) IANA, one to Novell/IPX, and one used
for IEEE 802 addressing.

Individual AD numbers should be assigned only when there is an
expectation that the delegated authority will need to assign on the
order of a million network numbers (an AD has space for 16 million
networks), or where a clear division of authority is required (e.g.  a
national administration).  Note that under the first of those
qualifications, the entire present Internet qualifies as only one AD.

4.2  ISO/ITU

Authority for assignments of ADs should eventually be vested in the
proper international organization, either the ITU and/or the ISO.
This is probably an issue that should eventually be taken up by the
proper committee of the Joint Technical Committee (JTC).

At present, the AD plan borrows an existing numbering plan for
countries, IS 3166.  This plan provides for two-letter, three-letter,
and three-digit codes for countries, where a country is a member of
the UN, or a (possibly disputed) territory or other area recognized by
the UN.  (Note that this includes the idea of the UN simply

Internet draft          Initial AD Assignment Plan          May 26, 1993


recognizing that the area is disputed; see the entity coded "NT" in
the 1988 two-letter code.)

The Internet already uses IS 3166 as the authority for the two-letter
top-level names used in the domain naming system to delegate naming to
national authority.

5  Country blocks

Each country (using the definitions of IS 3166) is assigned a block of
256 AD numbers, i.e.  a 16 bit number at the top of the numbering
plan.  The specific block number is derived from the three digit code
(ISO-3) assigned by IS 3166.  The first octet has value 120 plus ISO-3
divided by 250.  The second octet has the value ISO-3 modulo 250.
This assigns AD blocks in the range 120.0 to 123.249.

The fact that this assigns "large" blocks in some cases to very small
countries is not considered to be important.  (Rather, the premise
that all countries should have equal "importance" in the numbering
system is considered paramount.)

This is not a geographical assignment system.  The assignments are
administrative, delegated to national authority.  A network assigned
within a country-derived AD may be physically located anywhere.

While it is advisable for a country to assign individual ADs, there is
nothing to preclude a national plan using the entire country block;
that decision is specifically reserved to the national authority.  The
question as to whether the numbering plan within the ADs or block
should be correlated with topology, geography, or other constraints is
also reserved to national authority.  It should be kept in mind that
the DNS architecture requires that major authority delegations be made
on octet boundaries.

Certain large countries may need additional block assignments
eventually.  If the ISO or ITU authority is established at that time,
assignments will be made by the appropriate procedure within ISO
and/or the ITU.  If not, the national authority should apply to the
IANA, requesting information on where and how to proceed.

6  Initial IANA block

The block authority for AD numbers beginning with 126.0 is assigned to
IANA for individual AD assignements with international scope.  Only
one of the ADs in this block, 126.0.0, is presently assigned.

6.1  Version 4 Zone

The AD 126.0.0 is assigned to the present Version 4 numbering plan.
This AD has a specific plan for assignments within it:  the first 24
bits are the AD (126.0.0), the next 8-24 bits are a network number,
each assigned to a specific organization, and the remaining 16-40 bits
are assigned to subnets and hosts by authority reserved to the
specific organization.

7  Novell IPX

The internetwork protocol (IPX) used by products of Novell Corporation
and other vendors making interoperable software have used a 32-bit LAN
network number, implicitly concatenated with the 48 bit MAC layer
address to form an internet address.  The network numbers were not
assigned by any central authority, and thus were not useful for
inter-organizational traffic without substantial prior arrangement.

There is now an authority, established by Novell, to assign unique
32-bit numbers and blocks of numbers, to organizations that desire the
ability to do inter-organization networking with the IPX protocol.
Novell has also standardized the encapsulation of IPX over the
Internet Protocol.  [RFC1234]

The Novell/IPX numbering plan is assigned the block 126.1 within the
Version 7 numbering plan.  It has a specific structure for numbering
within the block:  the first 16 bits are the Novell/IPX block number
(126.1), the next 32 bits are the unique network number assigned to
the LAN, and the last 16 bits are a host number assigned, probably by
a (to be specified) dynamic method within the LAN.

The existance of a number within the Novell/IPX block for a host does
not imply that the host is Novell protocol capable, the number is
equally useful for both IP version 7 and IPX.

The dynamic method for local address assignment might be specific to
IPX, or it might be the general method used for any IPv7 local network
with 16 bits of host number.

While the assignment of a block, rather than a single AD number, is
exceptional, in view of the very large base of Novell systems it seems
reasonable to accomodate the 32-bit IPX network numbers directly.

In particular, RAP can be used to route IPv4, IPv7, and IPX/IPv7
traffic in a combined network.

8  IEEE 802 block

The IEEE block provides a local address for any host with a LAN
interface.  The address format is fixed:  the first 16 bits are the
block number, 126.2, the remaining 48 bits are the address assigned to
the host (or interface card, which is more typical).  The 802 address
is in canonical bit order [ref tbs].

Because addresses in this block do not have any useable struture, the
host is unlikely to be able to communicate beyond the local network.
The routing protocol may propagate routes to individual hosts a short
distance (i.e.  into adjacent LANs) but is unlikely to advertise them
very widely.

Internet draft          Initial AD Assignment Plan          May 26, 1993


The primary use for addresses in this block is to give hosts an
immediately useable address, without any prior configuration.  This
permits the host to then initiate an auto-configuration protocol with
a local net manager, authenticate itself, and find out or register its
name and/or wide area Internet address.

It also provides a permanent address for simple hosts that do not want
to communicate off of the LAN, such as a toaster.  It does not provide
actual security, and MUST NOT be used in an attempt to prevent access
except (e.g.) via an application relay:  the routing protocol(s) MAY
propagate a route to the host an arbitrary distance.  Hosts that begin
with an 802 derived address and then do autoconfiguration SHOULD
continue to recognize the address after the configuration is complete,
and MAY originate new traffic from that address.

Hosts using an address in this block MUST be capable of replying to
ARP requests, and hosts tring to reach such a host MUST use ARP (or
other defined ES-IS-like protocol) to resolve the address (and,
implicitly, determine which interface to use to reach the other host),
they MUST NOT extract the 802 address from the IPv7 address.

Digression:  note that there is a presumption here that it is
reasonable behavior for any host or router to ARP for an address that
it has no particular route for.  In the presence of general proxy-ARP,
this is indeed a reasonable idea, given that someone out there may be
able to reply.  This means that a TP/IX-IPv7 host need not necessarily
give addresses in this block special treatment in the IP layer route
resolution.

In the future, as "addresses" are pushed more toward the proper role
as endpoint-identifiers, and not used to route datagrams, this block
may become more useful.

Description of Working Group:
 
	TP/IX is a new version of the IP and TCP/UDP protocols, to
	advance the Internet technology to the scale and performance of
	the next generation of internetwork technology. TP/IX has been
	assigned the IP Protocol Identifier 7.

	The Working Group is chartered to review the TP/IX and RAP
	protocols, evaluate issues arising during product development
	and deployment planning, and to document problems and
	explanations for any parts of the coexistance with IPv4 not
	covered directly in the TP/IX-IPv4 interoperation design.

	The WG will also be the initial forum for development of the RAP
	protocol while it is experimental; this work will need to be moved
	to the Routing Area when it is to be advanced.
 
 Goals and Milestones: 
 
     Done Present the TP/IX and the RAP protocols to the IETF Plenary.  

   May 93 Post the TP/IX Protocol and the RAP protocol as Experimental RFCs.   

   Jul 93 Hold Working Group meeting to discuss additional definitions.  
          Prepare criteria to be met prior to standardization.                 

   Nov 93 Hold Working Group meeting to evaluate the TP/IX and RAP protocols 
          for Proposed Standard.                                               

   Dec 93 Submit the TP/IX and RAP Protocols to the IESG for consideration as a
          Proposed Standard.

Shouldn't that be IP Version number 7, not Protocol Identifier 7?  IP
Protocol numbers identify transport protocols.
