Java-Based Framework for Implementing Soft Real-Time Distributed Applications

Abstract-Nowadays, due to the development of various research domains such as groupware, multimedia, and WWW among others, distributed applications require more real-time capabilities to efficiently transfer monomedia and multimedia information between cooperating sites. In last years, Java became unavoidable for the development of distributed applications.Although the Real-Time Specification for Java (RTSJ) proposereal-time supports, it only remains a suited solution for specific monoprocesor real-time operating systems. Thus, providing dedicated mechanisms to support Java real-time distributed applications on standard operating systems appears as a main challenge.In this work, we propose a Java-based framework for designing/implementing soft real-time distributed applications. This framework focuses on providing central advantages: first, it is ldquoflexiblerdquo because it makes possible to define several scenarios to implement an application. It is adaptable because it is possible to adapt the class structure to satisfy the application requirements.Finally, it defines a dynamic infrastructure that allows clients and servers to exchange components at runtime.
