H ighly Penorm abie and Scalable Game Server Architecture tor M a ssiv e ly M ultiplayer Online R o le-P layin g Games

The gam e server system for a massively multiplayer online role-playing g am e (M M O R P G) must be of high performance so that it can handle a large number of request messages from game players (client PCs). In addition, it m ust be of high scalability so that it can easily adapt to an increasing or decreasing number of game players just by adding or removing physical game server components. This paper describes a distributed architecture and functional components of a game server system with nigh performance and scalability. The game server system mainly consists of a login server group, a user management server group, a zone server group, and a DB server and agent group. The login server group deals with the game players login requests, the user management server group deals w ith the gam e players locations, states, and movements. The zone server group manages the virtual environm ent of game. The D B server and agent group deals w ith m any D B access requests from other gam e server groups. In short, these gam e server groups interact one another to accept request messages from game players and respond to them as quickly as possible. Lastly, these server groups have the capability of fault tolerance so that they can provide services even in the presence of a certain level of component failures.
