So far the distribution of load, caused by the players in these games, is not distributed dynamically. After the launch of a new game, the introduction of new content, during special ingame events, or also during normal operations, players tend to concentrate in certain regions of the game worlds and cause overload conditions. Therefore we propose the use of structured P2P technology for the server infrastructure of the MMOGs to improve the reliability and scalability. Previous work segmented the game work into rectangular areas; however this approach often split a group of players to different servers, causing additional overhead. This work presents a cluster-based Peer-to-Peer approach, which can be used for load balancing in MMOGs or in other virtual worlds. The system is able to dynamically adapt to the current state of the game and handle uneven distributions of the players in the game world. We show through simulation, also with traces from real online games, that the cluster-based approach performs better than the previous P2P-based systems, which split the world in rectangular areas.

Massively multiplayer online games (MMOGs) are becoming increasingly popular today. However, even high-budget titles like World of Warcraft that have gone through extensive betatesting suffer from downtimes because of hard- and software problems. Our approach is to use structured P2P technology for the server infrastructure of MMOGs to improve their reliability and scalability. Such P2P networks are also able to adapt to the current state of the game and handle uneven distributions of the players in the game world. Another feature of our approach is being able to add supplementary servers at runtime. Our system allows using off-the-shelf PCs as infrastructure peers for participation in different game worlds as needed. Due to the nature of the Economy of Scale the same number of hosts will provide a better service than dedicated servers for each game world.
