A Flexible Middleware for Multimedia Communication: Design, Implementation, and Experience

By Burkhard Stiller, Christina Class, Marcel Waldvogel, Germano Caronni, Daniel Bauer and Bernhard Plattner


Distributed multimedia applications require a variety of communication services. These services and different application requirements have to be provided and supported within (1) end-systems in an efficient and integrated manner, combining the precise specification of Quality-of-Service (QoS) requirements, application interfaces, multicast support, and security features, and within (2) the network. The Da~CaPo++ system presented here provides an efficient end-system middleware for multimedia applications, capable of handling various types of applications in a modular fashion. Application needs and communication demands are specified by values in terms of QoS attributes and functional properties, such as encryption requirements or multicast support. Da~CaPo++ automatically configures suitable communication protocols, provides for an efficient run-time support, and offers an easy-to-use, object-oriented application programming interface. While its applicability to real-life applications was shown by prototype implementations, performance evaluations have been carried out yielding practical experiences and numerical results
