The 10th edition of the annual International Workshop on Network and Systems Support for Games (NetGames) will be held at the University of Ottawa in Ottawa, Canada, on October 6-7 2011. As in previous years, NetGames brings together researchers and practitioners from both academia and industry to present the latest research results and challenges of today’s networked games, and to understand their requirements and possibilities in order to enable the next generation of networked games. We will also also have industry keynote and panel discussions with leading researchers and practitioners from gaming companies.Contributions can be submitted as full papers, posters, or demos. In addition, accepted full papers are invited to submit a technically extended version of their work to a special issue on Network and Systems Support for Games in Springer's Multimedia Systems Journal. Please follow the Call for Papers link for more details.
