Thisstate-of-the-artsurveyoftechnologies,algorithms,models,andexperiments in the area of Internet Quality of Service is the ?nal report of COST (European Cooperation in the ?eld of Scienti?c and Technical Research) Action 263,Qu- ity of future Internet Services, http://www. fokus. fraunhofer. de/cost263 (QofIS). COST 263 ran from January 1999 until October 2003 with the participation of some 70 researchers from 38 organizations from 14 European countries (France, Hungary, Italy, Sweden, UK, Belgium, Germany, the Netherlands, Portugal, Slovenia, Switzerland, Finland, Greece, Romania, and Spain). The Action - longed to the COST area "Multimedia and Internet Communication"; together with COST 264, Networked Group Communication, this Action continued the e?ort started in 1992 by COST 237, Multimedia Telecommunications Services. Both groups have combined their e?orts now in the Network of Excellence in Emerging Networking Experiments and Technologies, http://www. ist-e-next. net (E-NEXT) of the 6th European Framework program. The book consists of seven chapters that were written in 18 months by 67 individual authors.The main objective of this book is to report the state of the art in the area of QofIS, as percieved by the authors, including achievements that wereoriginatedby the authors. The book wasdesigned in a top-downm- ner: after three years of running the Action with close co-ordination of research e?orts, it was easy to achieve a consensus on the table of contents. To ensure the content quality the following roles were de?ned and assigned to COST 263 members: chapter editor, chapter author, chapter reader.

The Second International Workshop on Traffic Monitoring and Analysis (TMA 2010) was an initiative of the COST Action IC0703 "Data Traffic Monitoring and Analysis: Theory, Techniques, Tools and Applications for the Future Networks" (http:// www.tma-portal.eu/cost-tma-action). The COST program is an intergovernmental framework for European cooperation in science and technology, promoting the coordination of nationally funded research on a European level. Each COST Action aims at reducing the fragmentation in - search and opening the European research area to cooperation worldwide. Traffic monitoring and analysis (TMA) is nowadays an important research topic within the field of computer networks. It involves many research groups worldwide that are collectively advancing our understanding of the Internet. The importance of TMA research is motivated by the fact that modern packet n- works are highly complex and ever-evolving objects. Understanding, developing and managing such environments is difficult and expensive in practice. Traffic monitoring is a key methodology for understanding telecommunication technology and improving its operation, and the recent advances in this field suggest that evolved TMA-based techniques can play a key role in the operation of real networks.
