Abstract

QoS-based routing has been recognized as a missing piece in the evolution of QoS-based service offerings in the Internet. This document describes some of the QoS-based routing issues and requirements, and proposes a framework for QoS-based routing in the Internet. This framework is based on extending the current Internet routing model of intra and interdomain routing to support QoS.

ABSTRACT

QoS-based routing has been recognized as a missing piece in the

evolution of QoS-based service offerings in the Internet. This

document describes some of the QoS-based routing issues and

requirements, and proposes a framework for QoS-based routing in the

Internet. This framework is based on extending the current Internet

routing model of intra and interdomain routing to support QoS.

1. SCOPE OF DOCUMENT & PHILOSOPHY

This document proposes a framework for QoS-based routing, with the

objective of fostering the development of an Internet-wide solution

while encouraging innovations in solving the many problems that

arise. QoS-based routing has many complex facets and it is

recommended that the following two-pronged approach be employed

towards its development:

1. Encourage the growth and evolution of novel intradomain QoS-based

routing architectures. This is to allow the development of

independent, innovative solutions that address the many QoS-based

routing issues. Such solutions may be deployed in autonomous

systems (ASs), large and small, based on their specific needs.

2. Encourage simple, consistent and stable interactions between ASs

implementing routing solutions developed as above.

This approach follows the traditional separation between intra and

interdomain routing. It allows solutions like QOSPF [GKOP98, ZSSC97],

Integrated PNNI [IPNNI] or other schemes to be deployed for

intradomain routing without any restriction, other than their ability

to interact with a common, and perhaps simple, interdomain routing

protocol. The need to develop a single, all encompassing solution to

the complex pro...
