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.
