Guidelines for the use of Internet-IP addresses in the

ISO Connectionless-Mode Network Protocol

Status of This Memo

This RFC suggests an addressing scheme for use with the ISO

Connectionless Network Protocol (CLNP) in the Internet. This is a

solution to one of the problems inherent in the use of "ISO-grams" in

the Internet. This RFC suggests a proposed protocol for the Internet

community, and requests discussion and suggestions for improvements.

Distribution of this memo is unlimited.

This memo is a revision of RFC 986. Changes were made in order to

allow the addressing used in the CLNP in the Internet to be

potentially useful for routing in the context of new inter- and

intra-domain routing protocols, and in the context of large numbers

of networks and routing domains. The addressing scheme proposed in

this RFC allows individual routing domains to make use of internal

routing algorithms utilizing a variety of addressing formats, while

still providing for a common addressing approach for use by inter-

domain routing. These features are important due to the rapid growth

currently being experienced in the Internet.

1. Objectives

The data communications protocols currently emerging out of the

international standardization efforts warrant an early integration

into the existing extensive Internet network infrastructure. The two

possible approaches are a top-down one, where ISO applications like

FTAM, X.400 and VTP are integrated on top of the transport function

of the IP protocol suite, or a bottom-up approach where the whole ISO

tower gets integrated without merging the two suites. The bottom-up

approach may make use of the fact that the ISO-CLNP and the IP are

very similar in function. This implies that it is reasonable to

implement a multiprotocol function in some or all of the Internet

gateways (potentially including part or all of the Internet

environment). The result would be that at least large portions of

the Internet, in particular the backbones, can become usable for full

implementations of the ISO protocol stack.

A major problem with this approach is that there are open issues with

regard to the ISO addressing within the CLNP. In particular, the ISO

network layer addressing standard allows a great deal of flexibility

in the assignment of addresses, and a particular address format must

be chosen. A further problem is the need for implementation and

integration of routing facilities for the ISO-compatible subset of

the Internet environment.
