Abstract

This document outlines the issues and framework related to providing

IP Integrated Services with RSVP over ATM. It provides an overall

problems are to be addressed in further documents from the ISATM

subgroup of the ISSLL working group.

1. Introduction

The Internet currently has one class of service normally referred to

as "best effort." This service is typified by first-come, first-

serve scheduling at each hop in the network. Best effort service has

worked well for electronic mail, World Wide Web (WWW) access, file

transfer (e.g. ftp), etc. For real-time traffic such as voice and

video, the current Internet has performed well only across unloaded

portions of the network. In order to provide quality real-time

traffic, new classes of service and a QoS signalling protocol are

being introduced in the Internet [1,6,7], while retaining the

existing best effort service. The QoS signalling protocol is RSVP

[1], the Resource ReSerVation Protocol and the service models

One of the important features of ATM technology is the ability to

request a point-to-point Virtual Circuit (VC) with a specified

Quality of Service (QoS). An additional feature of ATM technology is

the ability to request point-to-multipoint VCs with a specified QoS.

Point-to-multipoint VCs allows leaf nodes to be added and removed

from the VC dynamically and so provides a mechanism for supporting IP

multicast. It is only natural that RSVP and the Internet Integrated

Services (IIS) model would like to utilize the QoS properties of any

underlying link layer including ATM, and this memo concentrates on

ATM.
