Evaluating P2P Live Streaming Systems: the CNG Case

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 example to illustrate them. The evaluation of the P2P system 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.
