 Supporting Massively Multiplayer Online Games on Peer-to-Peer Overlays

About the talk:
 
We present an approach to support massively multi-player games (MMG) on peer-to-peer overlays. Our approach exploits the fact that players in MMGs display locality of interest, and therefore can form self-organizing groups based on their locations in the virtual world. To this end, we have designed scalable mechanisms to distribute the game state to the participating players and to maintain consistency in the face of node failures. The resulting system dynamically scales with the number of online players. It is also more flexible and has a lower deployment cost than centralized game servers.
                                                                                
We have implemented a simple game we call SimMud, and experimented with up to 4000 players to demonstrate the applicability of this approach. I will discuss the design and experimental results of our prototype, as well as future research in performance optimizations and cheat detection.
