Abstract

This paper provides guidelines for allocating NSAP addresses in the Internet. The guidelines provided in this paper have been the basis for initial deployment of CLNP in the Internet, and have proven very valuable both as an aid to scaling of CLNP routing, and for address administration.

Abstract

CLNP is currently being deployed in the Internet. This is useful to support OSI and DECnet(tm) traffic. In addition, CLNP has been proposed as a possible IPng candidate, to provide a long-term solution to IP address exhaustion. Required as part of the CLNP infrastructure are guidelines for network service access point (NSAP) address assignment. This paper provides guidelines for allocating NSAP addresses in the Internet.

The guidelines provided in this paper have been the basis for initial deployment of CLNP in the Internet, and have proven very valuable both as an aid to scaling of CLNP routing, and for address administration.
