                 ATM Signaling Support for IP over ATM

Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This memo describes the ATM call control signaling exchanges needed
   to support Classical IP over ATM implementations as described in RFC
   1577 [LAUB94]. ATM endpoints will incorporate ATM signaling services
   as specified in the ATM Forum User-Network Interface (UNI)
   Specification Version 3.1 [ATMF94]. IP over ATM implementations
   utilize the services of local ATM signaling entities to establish and
   release ATM connections. This memo should be used to define the
   support required by IP over ATM implementations from their local ATM
   signaling entities.

   This document is an implementors guide intended to foster
   interoperability among RFC 1577, RFC 1483, and UNI ATM signaling.  It
   applies to IP hosts and routers which are also ATM endsystems and
   assumes ATM networks that completely implement the ATM Forum UNI
   Specification Version 3.1. Unless explicitly stated, no distinction
   is made between the Private and Public UNI.

RFC 1755         ATM Signaling Support for IP over ATM     February 1995

   UNI 3.1 is considered an erratum to the UNI 3.0 specification. It has
   been produced by the ATM Forum, largely for reasons of alignment with
   Recommendation Q.2931. Although UNI 3.1 is based on UNI 3.0 there are
   several changes that make the two versions incompatible. A
   description of how to support IP over ATM using UNI 3.0 is found in
   Appendix B.
