Abstract

   This memo presents specific implementation guidelines for running
   RSVP over ATM switched virtual circuits (SVCs).  The general problem
   is discussed in [6].  Implementation requirements are discussed in
   [2].  Integrated Services to ATM service mappings are covered in [3].
   The full set of documents present the background and information
   needed to implement Integrated Services and RSVP over ATM.

1. Introduction

   This memo discusses running IP over ATM in an environment where SVCs
   are used to support QoS flows and RSVP is used as the internet level
   QoS signaling protocol.  It applies when using CLIP/ION, LANE2.0 and
   MPOA methods for supporting IP over ATM.  The general issues related
   to running RSVP[4] over ATM have been covered in several papers
   including [6] and other earlier work.  This document is intended as a
   companion to [6,2] and as a guide to implementers.  The reader should
   be familiar with both documents.

   This document provides a recommended set of functionality for
   implementations using ATM UNI3.x and 4.0, while allowing for more
   sophisticated approaches.  We expect some vendors to additionally
   provide some of the more sophisticated approaches described in [6],
   and some networks to only make use of such approaches.  The
   recommended set of functionality is defined to ensure predictability
   and interoperability between different implementations.  Requirements
   for RSVP over ATM implementations are provided in [2].
