Abstract

We describe a collection of algorithms designed to support reliable synchronization and group membership services for distributed multimedia applications. In particular, we consider those applications that require interactivity, isochronous rendering of multimedia data, and high reliability. We show that the algorithms we propose (i) provide reliable support for the synchronization of multimedia data streams, despite the occurrence of possible communication failures, (ii) maintain a consistent view of the relative group membership of all the nonfaulty application components, (iii) guarantee time-bounded delay of component failure detection and join, and (iv) meet effectively possible scalability requirements of the applications.
