This volume of the Lecture Notes in Computer Science series publishes the set of papers accepted for the ICQT 2006 workshop, i.e., the 5th International Workshop on Internet Charging and QoS Technology (ICQT), which was collocated with ACM SIGMETRICS. These events took place in St. Malo, France and were hosted by the IUT (Institut Universitaire Technologique) of St. Malo. QoS-guaranteed services enable a huge variety of prosperous business models, and the need for viable models and pricing schemes is urgent. The resulting combination of technical and economic perspectives drives many relevant...

Starting with the imminent roll-out of the IP Multimedia Subsystem (IMS) and fourth-Generation networking technology, Next Generation Networks (NGN) are gradually becoming reality, with charging and Quality-of-Service (QoS) issues as two of the key drivers for the evolution toward the convergent all-IP network of the future. Therefore, the 6th International Workshop on Internet Charging and QoS Technology (ICQT 2009) was devoted to discussing the most recent approaches, models, and mechanisms in this highly interesting and important research area. The present volume of the Lecture Notes in...
