A Distributed Jini Technology-based Conferencing System Design And Implementation

With the popularization of networks and the applications via net, traditional way of net connecting could no longer satisfy people's explosive demand. It calls for a more explicit and robust way of net connecting. Just as the phone network, people don't need any operation on the terminals. By pluging the interfaces, phone could be easily connected to the networks. Meanwhile, any one or group of equipments deattaced from the network will make no impact to the others. In order to satisfy the need , Sun proposed a dynamic and distributive structure----Jini. According to the criterion of Jini structure and official documents of Sun Microsystems, Jini is defined as follows. "A Jini system is a distributed system based on the idea of federating groups of users and the resources required by those users. The overall goal is to turn the network into a flexible, easily administered tool with which resources can be found by human and computational clients. Resources can be implemented as either hardware devices, software programs, or a combination of the two. The focus of the system is to make the network a more dynamic entity that better reflects the dynamic nature of the workgroup by enabling the ability to add and delete services flexibly."From the above definition, it is not difficult to find that the object of Jini is to construct a dynamic and distributive plug-and-play network. Focusing on it, this paper firstly discusses the structure of Jini, its objective, proposition and component. Then, it discusses the way to construct dynamic distributive groups via Jini components, analyzes the difference between Jini and traditional distributive systems, pointing out the reason to use Jini techniques in constructing the distributive meeting system.
