Abstract

This RFC proposes a scenario for experimentation with the International Organization for Standardization (ISO) Open Systems Interconnection (OSI) network layer protocols over the Internet and requests discussion and suggestions for improvements to this scenario. This RFC also proposes the creation of an experimental OSI internet. To participate in the experimental OSI internet, a system must abide by the agreements set forth in this RFC.

Use of the Internet as a Subnetwork for Experimentation with the OSI Network Layer

Status of this Memo

This RFC proposes a scenario for experimentation with the International Organization for Standardization (ISO) Open Systems Interconnection (OSI) network layer protocols over the Internet and requests discussion and suggestions for improvements to this scenario. This RFC also proposes the creation of an experimental OSI internet. To participate in the experimental OSI internet, a system must abide by the agreements set forth in this RFC. Distribution of this memo is unlimited.

WARNING

The methods proposed in this RFC are suitable ONLY for experimental use on a limited scale. These methods are not suitable for use in an operational environment.

Introduction

Since the International Organization for Standardization (ISO) Open Systems Interconnection (OSI) network layer protocols are in their infancy, both interest in their development and concern for their potential impact on internetworking are widespread. This interest has grown substantially with the introduction of the US Government OSI Profile (GOSIP), which mandates, for the US Government, the use of OSI products in the near future. The OSI network layer protocols have not yet received significant experimentation and testing. The status of the protocols in the OSI network layer varies from ISO International Standard to "contribution" (not yet a Draft Proposal). We believe that thorough testing of the protocols and implementations of the protocols should take place concurrently with the progression of the protocols to ISO standards. For this reason, the creation of an environment for experimentation with these protocols is timely.

internetworking requires a large, varied, and complex environment. While an implementor of the OSI protocols may of course test an implementation locally, few implementors have the resources to create a sufficiently large dynamic topology in which to test the protocols and implementations well.

One way to create such an environment is to implement the OSI network layer protocols in the existing routers in an existing internetwork. This solution is likely to be disruptive due to the immature state of the OSI network layer protocols and implementations, coupled with the fact that a large set of routers would have to implement the OSI network layer in order to do realistic testing.

This memo suggests a scenario that will make it easy for implementors to test with other implementors, exploiting the existing connectivity of the Internet without disturbing existing gateways.

The method suggested is to treat the Internet as a subnetwork, hereinafter called the "IP subnet." We d...
