Local coordination for interpersonal communication systems

Abstract (Summary)
The decomposition of complex applications into modular units is an acknowledged design principle for creating robust systems and for enabling the flexible re-use of modules in new application contexts. Typically, component frameworks provide mechanisms and rules for developing software modules in the scope of a certain programming paradigm or programming language and a certain computing platform. For example, the JavaBeans framework is a component framework for the development of component-based systems — in the Java environment. In this thesis, we present a light-weight, platform-independent approach that views a component-based application as a set of rather loosely coupled parallel processes that can be distributed on multiple hosts and are coordinated through a protocol. The core of our framework is the Message Bus (Mbus): an asynchronous, message-oriented coordination protocol that is based on Internet technologies and provides group communication between application components. Based on this framework, we have developed a local coordination architecture for decomposed multimedia conferencing applications that is designed for endpoint and gateway applications. One element of this architecture is an Mbus-based protocol for the coordination of call control components in conferencing applications.
