Status of this RFC:

 This document is distributed as an RFC for information only.  It does
 not specify a standard for the ARPA-Internet.  Distribution of this
 document is unlimited.

Note:

 This document has been prepared by retyping the text of ISO/DP8348/DAD2
 of October 1984 (also numbered SC 6/N 3444), which is currently
 undergoing voting within ISO as a Draft Proposed Addendum to the
 Network Service Definition.  Although this RFC has been reviewed after
 typing, and is believed to be substantially correct, it is possible
 that typographic errors not present in the ISO document have been
 overlooked.

RFC 941                                                       April 1985

ISO Statement on the Status of this Document.

At its meeting in Zurich, April 2-11, 1984, SC 6/WG 2 produced document
SC 6 N 3134 and, in accordance with Resolution 49 of the SC 6 meeting in
Tianjin (September 19-30, 1983), forwarded it to the SC 6 Secretariat
for registration and ballot as a first Draft Proposed Addendum to the
Network Service Definition (ISO DP 8348/DAD2).

The letter ballot on SC 6/N 3134 closed on August 20, 1984. The results
of the ballot were 10-4-0-3 [approve-disapprove-abstain-no vote]; the
summary of voting is contained in document SC 6/N 3229 (late votes are
contained in documents SC 6/N 3333 and 3360). These ballot results were
reviewed at the SC 6/WG 2 meeting in Washington, October 15-25, 1984,
and document SC 6/N 3444 was produced as a progression of SC 6/N 3134,
taking into account as many of the ballot comments as possible.  The
Editor's report, contained in document SC 6/N 3445, describes the
disposition of member body comments on the DP 8348/DAD2 letter ballot.

A resolution of the SC 6 meeting in Washington, October 22-26, 1984,
instructs the SC 6 Secretariat to register document SC 6/N 3444 as a
second Draft Proposed Addendum to ISO 8348, and to circulate it for a
two-month letter ballot.

Introduction

This Addendum to the Network Service Definition Standard, ISO 8348,
defines the abstract syntax and semantics of the Network Address
(Network Service Access Point Address).  The Network Address defined in
this Addendum is the address that appears in the primitives of the
connection-mode Network Service as the calling address, called address,
and responding address parameters, and in the primitives of the
connectionless-mode  Network  Service  as  the source address and
destination address parameters.

ISO/TC-97/SC-6                                                  [Page 2]

RFC 941                                                       April 1985
Network Layer Addressing

  SCOPE AND FIELD OF APPLICATION

The scope of this Addendum is the definition of the abstract syntax and
semantics of the Network Address.  This Addendum does not specify the
way in which the semantics of the NSAP address are encoded in Network
Layer protocols.  The field of application of this Addendum is the same
as the field of application described in Clause 1 of the Network Service
Definition (ISO 8348).
