In this paper, we present a design framework of interactive distance leaning (IDL) in distributed system environment. In this design framework, interactive distance learning (IDL) system is based on Java technology: Jini technology and Java Media Framework (JMF). Using Java language, a developed system is a platform independent both in software, e.g. operating systems (OS), and hardware, e.g. computer and mobile devices. Any target systems that can run Java Virtual Machine (JVM) are able to run our IDL. In addition, it also gives us a low complexity of implementation. To work with any firewalls in a network, we have proposed an IDL gateway which allows us to not only solve the packet blocking problem but also to solve the multicast address problem. Moreover, the framework supports fully distributed services. For example service and database engines could be in separated physical location, e.g. video server and database server. This allows system scale up easily with small limited conditions. We have demonstrated our prototype software to show that it is working effectively.
