The 2001 International Workshop on Quality of future Internet Services (QofIS 2001) held in Coimbra, Portugal, organized by COST Action 263, is the second of what we expect will become a series of successful QofIS workshops. The previous workshop was held in Berlin in the year 2000. The areas of interest of QofIS cover the design, implementation and provision of Quality of Service, spanning key issues of current and emerging communication systems such as packet-level issues, flow-level issues, network-level issues, architectural issues, and applications. The emphasis of the QofIS2001 w orkshop is on horizontal (end-to-end) as well as vertical (top-down) provision of quality of services, covering all components of end systems and networks, with the aim of identifying solutions enabling feasible and coherent QoS provision. The QofIS2001 cal l for papers attracted 87 submissions from 23 Asian, Australian, European, North American, and South American countries. These were subject to thorough review work by the Programme Committee members and additional reviewers who carried out their work using a specially built conference system, WebChairing, developed in Coimbra by Flor de Utopia, that allowed full control of the submission and reviewing processes. Based on the comments and recommendations of the reviews, the final programme was defined in a Programme th Committee meeting held at the University of Karlsruhe on June 5 , 2001.
