QoS and routing in the cognitive packet network

We present experimental results on an autonomic network test-bed, the cognitive packet network (CPN), designed for research in adaptive quality-of-service (QoS) management. CPN is fully compatible at its edges with the Internet Protocol, while internally it offers dynamic routing based on on-line sensing and monitoring. CPN can implement distributed adaptive shortest-path routing, and we compare it with minimum-delay based routing and a composite approach.
