The three IST projects AQUILA, CADENUS and TEQUILA investigate IP Quality of Service support in large IP networks. The main objective of the projects is the same: providing Premium IP services over the Internet as a basic step towards the Next Generation Networks (NGN) of tomorrow. All the partners involved in these three projects consider that having this common goal is a very positive fact (since the acceptance of three projects shows that this is one of the most important concerns of today's research in IP services and networks) and an excellent opportunity to investigate the technical feasibility of different approaches for addressing this shared concern. The common goal and, by consequence, the unavoidable overlap of some of the technical areas being investigated by the three projects, is judged as a strength and opportunity of the IST Premium IP cluster and not at all as a threat or a weakness.

This jointly prepared deliverable contains a brief description of the three projects in terms of objectives, architecture, service and resource management. The common goal of the Premium IP cluster projects as well as differences and their complementary approaches are presented, so that the projects are "comparable" by means of tables, which allow the reader to easily assess complementary approaches and the (main) differences between the projects. In addition, the document reports on current co-operative activities like Monitoring and Measurement or contributions to IETF, as well as future activities like collaboration with the IST project INTERMON or validation through trials.
