There are many reasons to consider QoS-based routing as a component of the integrated services Internet. But several questions arise with regard to its development: what are the requirements on QoS-based routing in the Internet? What sort of a routing architecture is practical? What are the technical and policy issues that arise in realizing a QoS-based Internet routing architecture? This draft is an attempt to generate some discussion on these topics. To this end we present some potential requirements on path computation, efficiency, robustness and scalability, and describe some issues in realizing a QoS-based routing architecture. Our conclusions are that QoS-based routing is a challenging problem, and that it each of its major components, path computation, scalability and administrative control present their own set of issues that must be addressed in developing the routing architecture.
