TY - CONF T1 - Evaluating P2P Live Streaming Systems: the CNG Case T2 - The Seventeenth International Conference on Distributed Multimedia Systems, Convitto della Calza, Florence, Italy, 18 - 20 August Y1 - 2011 A1 - Christos Bouras A1 - Vaggelis Kapoulas A1 - Andreas Papazois A1 - S Ahmad A1 - R Hamzaoui A1 - A Sahni A1 - G Simon A1 - Elyia Buyukkaya AB - Many peer-to-peer (P2P) systems have been proposed for the provision of scalable live video streaming services over the Internet. While the literature contains surveys of the architectures of these systems, there is a lack of work on methodologies for their evaluation. We identify the main issues in the evaluation of P2P live streaming systems and use the Community Network Game (CNG) project as an ex- ample to illustrate them. The evaluation of the P2P sys- tem consists of two phases: a laboratory one using the ns-2 network simulator and an online field test with Massively Multiplayer Online Games (MMOG) players.

This will be achieved by developing new tools for the generation, distribution and insertion of user-generated content (UGC) into existing MMOGs without changing the game code and without adding new processing or network loads to the MMOG central servers. This UGC may include items (e.g., textures, 3D objects) to be added to the game and live video captured from the game screen and streamed to other players. We present the objectives of the project, focusing on its main scientific and technological contributions.

One of the most attractive features of Massively Multiplayer Online Games (MMOGs) is the possibility for users to interact with a large number of other users in a variety of collaborative and competitive situations. Gamers within an MMOG typically become members of active communities with mutual interests, shared adventures, and common objectives. We present the EU funded Community Network Game (CNG) project. The CNG project will provide tools to enhance col- laborative activities between online gamers and will develop new tools for the generation, distribution and insertion of user generated content (UGC) into existing MMOGs. CNG will allow the addition of new engaging community services without changing the game code and without adding new processing or network loads to the MMOG central servers. The UGC considered by the CNG project includes 3D objects and graphics as well as video to be shared using peer-to-peer (P2P) technology. We describe the concept, innovations, and objectives of the project.
