Abstract: Subject of this paper is the functional description and refinement of a connector service to manage dynamic interactions in multi-service agent platforms. At first, the concept of architectural frames will be introduced as a common development framework for application systems and interpreted for the class of agent systems. For the program-technical realization and execution of agent application systems, services are needed meeting the concepts of the architecture-based approach. Since platform services are based on application-independent building blocks and concepts, they are derived and developed by examining, analyzing and abstracting requirements of application-technical building blocks on platforms. This will be discussed for the aspect of interagent connections: a common process model of interagent connections will be introduced at next. Analyzing its partial processes, process types are identified and assigned to components of the connector service. The connector service will be modeled object-orientedly and mapped onto a multi-service agent platform named ADE corresponding to concepts of the architecture-based approach.
