Group Coordination Support in Networked Multimedia Systems

Abstract

Advances in computer hardware and networking technology have incited the deployment of large-scale group-oriented applications for delivery or interactive development of multimedia content in the Internet. There is a growing number of protocols and techniques for group communication and membership services in the IP-multicast framework, however, group coordination support for telecollaborative tasks such as videoconferencing or distributed interactive simulation has received little attention. In this dissertation, we address network control and coordination functions to orchestrate synchronous multimedia groupwork, establishing a sharing discipline on multimedia resources and guaranteeing consistency of distributed activities with ordered multicasting. We introduce a formal framework for group coordination and a turn-taking abstraction useful for evaluating coordination protocols. Elemental design choices for group coordination architectures and the concept of aggregated processing of coordination information are discussed.
