This memo presents specific implementation guidelines for running RSVP over ATM switched virtual circuits (SVCs). The general problem is discussed in . Implementation requirements are discussed in . Integrated Services to ATM service mappings are covered in . The full set of documents present the background and information needed to implement Integrated Services and RSVP over ATM.
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 over ATM have been covered in several papers including  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 , 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. Implementation Recommendations
This section provides implementation guidelines for implementation of RSVP over ATM. Several recommendations are common for all, RSVP sessions, both unicast and multicast. There are also recommendations that are unique to unicast and multicast session types.
2.1 RSVP Message VC Usage
The general issues related to which VC should be used for RSVP messages is covered in . It discussed several implementation options including: mixed control and data, single control VC per session, single control VC multiplexed among sessions, and multiple VCs multiplexed among sessions. QoS for control VCs was also discussed. The general discussion is not repeated here and  should be reviewed for detai...
