               RSVP over ATM Implementation Requirements

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 presents specific implementation requirements for running
   RSVP over ATM switched virtual circuits (SVCs).  It presents
   requirements that ensure interoperability between multiple
   implementations and conformance to the RSVP and Integrated Services
   specifications.  A separate document [5] provides specific guidelines
   for running over today's ATM networks.  The general problem is
   discussed in [9].   Integrated Services to ATM service mappings are
   covered in [6].  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 [4] methods for supporting IP over ATM.  The general issues
   related to running RSVP [8] over ATM have been covered in several
   papers including [9] and other earlier work.
