In building larger network information system, efficient management and transmission of huge information are important in several reasons. Firstly, the system will be driven into confusion without a perfect information management strategy faced with tremendous amount of information resources. Secondly, it is essential for the system to transmit huge information in a secure and efficient way in widely networking environment. Furthermore, the system with excellent compatibility and extensibility will be valuable because of system maintenance and update. In this paper, we propose a solution of a flexible distributed information delivery system DID to resolve those problems, which is based on the technique of software agent and CORBA. The design and implementation of DID system are described in detail.
