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...

This book constitutes the joint refereed proceedings of the 5th COST264 International Workshop on Networked Group Communications, NGC 2003, and the 3rd International Workshop on Internet Charging and QoS Technologies, ICQT 2003, held in Munich, Germany, in September 2003.The 25 revised full papers and 6 revised short papers presented were carefully reviewed and selected from a total of 78 submissions. The papers are organized in topical sections on application multicast support, anycast and search in peer-to-peer networks, peer-to-peer systems, security and multicasting, multicast mechanisms,...
