Applications Research Of Distributed Architecture Based JINI Services

With the rapid development and the pervasive applications of network and Internet, a large variety of devices and software are being connected continuously into network .The complexity of network use and maintenance becomes more and more great. So, comes the new need for distributed computing architecture. It is expected that the services provided by these devices and software can be used without being simply way as plug-and-play configured, installed and intervened by people in such a (PNP) once they plug into network. How to improve the service style, use the resources better and make the software services more convenient and flexible under network environment is a hot research of modern research.JINI supports services' dynamic registration and discovery and transfer. It makes software services have the ability of adaptable, self-healing, self-governing and distributed. As a real architecture based on service, it provides a new solution for PNP. JINI itself is a distributed environment. It's ability of distributed object technology and mobile code and it's mechanism of lookup service, renew, remote event and distributed transaction provides full support for services' programming, discovery and access.In this dissertation firstly analyzes the distributed architecture based services, and compares the now popular distributed technology such as CORBA, DCOM, JAVA/RMI. Under above discussion on the problem in the distributed architecture we discuss a new pattern to resolve the problems of the now distributed architecture: based JINI service distributed computing architecture. The advantages and shortage and foreground of the distributed computing architecture based JINI service are discussed. Does research in designing new after-selling fault diagnose architecture using JINI and mainly its dynamic release, discovery and lookup mechanism to get diagnose services, and makes elementary implement of pivotal technology. Finally, service semantic matching, rental expense and security are discussed In this dissertation.Otherwise, a service describing solution based on semantic method is given using xml technology according service discovery match style and practical application, thus achieve semantic level understandability and improve veracity.
