Network Working Group M. Perez Request for Comments: 1755 ISI Category: Standards Track F. Liaw FORE Systems, Inc. A. Mankin E. Hoffman ISI D. Grossman Motorola Codex A. Malis Ascom Timeplex, Inc. February 1995 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. Perez, Liaw, Mankin, Hoffman, Grossman & Malis [Page 1] 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.
