This volume of the Lecture Notes in Computer Science series contains the set of papers accepted for presentation at the 5th International Workshop on Quality of future Internet Services (QofIS 2004) and at the two one-day workshops - locatedwithQofIS2004,namelythe1stInternationalWorkshoponQoSRouting (WQoSR 2004) and the 4th International Workshop on Internet Charging and QoS Technology (ICQT 2004). QofIS 2004, the ?fth international event, was organized under the umbrella of the E-NEXT Network of Excellence on Emerging Networking Experiments and Technologies , which started its activities in January 2004. QofIS 2004 took place on September 29 30, 2004 at the Telef onica premises in Barcelona, and was arranged by the Universitat Polit` ecnica de Catalunya (UPC). QofIS 2004 in Barcelona followed the highly successful workshops in Stockholm in 2003, Zuric h in2002,Coimbrain2001,andBerlinin2000.ThepurposeofQofIS2004,asofall QofIS events, was to present and discuss design and implementation techniques for providing quality of service in the Internet.
