To make communication a comfortable experience for users, we have developed a middleware called Communication Service Concierge (CSC). This is a network middleware for distributed environments, and it consists of Communication Resource Management (CRM) and Communication Logic Management (CLM). Communication Service Concierge realizes comfortable communications by combining CRM and CLM. Communication Logic Management provides a framework to directly operate communication data. Communication Resource Management provides a framework on which downloadable software components can be executed on distributed platforms, and plays a primary role in controlling CSC's communication.Using Java, we implemented CRM on OSGi service platforms, which provide dynamic executions of the software components locally. In other words, CRM provides a distributed agent computing feature for OSGi. In this paper we describe the roles and implementations of CRM, especially for security functions, as well as describing how CRM's software components work cooperatively.
