Remodeling of Java based Distributed Environment using Local Bus System Architecture

In this study, we tried to remodel the distributed environment into a local bus system architecture for the purpose of achieving the simplicity and the uniformity of service accesses on Java based distributed environment. This new distributed environment model (UIBUS: Universal Interface Bus) is composed of four abstract devices - Arbiter, Bridge, Initiator and Target - and these devices communicate with each others through the simply-designed application level protocol (UIBUS protocol). As a result, an user application that want to access a service that exposed by specific device, can access it through the uniform communication interface as ti does in a local bus system architecture. In this paper we introduce the concept of UIBUS and its architecture. And also we present an implementation of UIBUS PAL (Protocol Abstraction Layer) for a typical TCP/IP based distributed environment to show that the proposed model is valid.
