Services which handle events occurring at servers are emerging recently in the Internet world. These services will be performed in accordance with each user's preference data. To offer such services, an agent-based architecture where an agent resides at a server as a user's proxy has been proposed. In such agent systems, an event distribution pattern which sends an event to agents when a database is updated is necessary. When we build large systems hosting hundreds of thousands of agents, we have to consider system-level factors such as performance and resource limitations in addition to complexity of programming. In this paper, we describe typical event distribution patterns for large systems of this kind. Important points to consider regarding the agent interaction patterns in such systems are identified.
