This document outlines the issues and framework related to providing
IP Integrated Services with RSVP over ATM. It provides an overall
approach to the problem(s) and related issues. These issues and
problems are to be addressed in further documents from the ISATM
subgroup of the ISSLL working group.
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
, 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
Classical IP over A...
