IETF RFC 2381
Interoperation of Controlled-Load Service and Guaranteed Service with ATM
|Publication Date:||1 August 1998|
This document provides guidelines for mapping service classes, and traffic management features and parameters between Internet and ATM technologies. The service mappings are useful for providing effective interoperation and end-to-end Quality of Service for IP Integrated Services networks containing ATM subnetworks.
The discussion and specifications given here support the IP integrated services protocols for Guaranteed Service (GS), Controlled-Load Service (CLS) and the ATM Forum UNI specification, versions 3.0, 3.1 and 4.0. Some discussion of IP best effort service over ATM is also included.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 . (Note, in many cases the use of "MUST" or "REQUIRED" reflects our interpretation of the requirements of a related standard, e.g., ATM Forum UNI 4.0, rsvp, etc.)
