Design principles: layering, protocols, interfaces; models for open distributed processing; real-time requirements; request-response and stream processing, real-time scheduling, design for performance and scalability; other quality of service issues; user perspective versus system performance parameters, cost/performance trade-offs, negotiations; adaptive and mobile applications; examples of multimedia applications and protocols.
Course objectives: The students will become familiar with the issues and design principles for distributed and mobile applications that adapt to quality of service requirements of the users and constraints imposed by the underlying communication networks and end-systems. They will also get acquainted with a good number of protocols and system designs that are used for practical distributed multimedia applications.
In the context of a course project, the student will study a particular topic in more depth by searching the literature and critically reading the pertinent papers which will be synthesized and summarized, or by doing some hands-on programming project related to the topic. The student will write a report on his project and give an oral presentation in class.
