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. |
