Network Working Group Richard Colella (NIST) Request for Comments: 1237 Ella Gardner (Mitre) Ross Callon (DEC) July 1991 Guidelines for OSI NSAP Allocation in the Internet Status of This Memo This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the ‘‘IAB Official Protocol Standards’’ for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Abstract The Internet is moving towards a multi-protocol environment that includes OSI. To support OSI in the Internet, an OSI lower layers infrastructure is required. This infrastructure comprises the connectionless network protocol (CLNP) and supporting routing protocols. Also required as part of this infrastructure are guidelines for network service access point (NSAP) address assignment. This paper provides guidelines for allocating NSAPs in the Internet. This document provides our current best judgment for the allocation of NSAP addresses in the Internet. This is intended to guide initial deployment of OSI 8473 (Connectionless Network Layer Protocol) in the Internet, as well as to solicit comments. It is expected that these guidelines may be further refined and this document updated as a result of experience gained during this initial deployment.
