In order to realize real-time communications on the Internet today, multimedia applications must be adaptive and must sense and react to the time-varying levels of bandwidth available to them. In this tutorial we will study the fundamental principles of the management of live multimedia data on the Internet. These include techniques for ameliorating the effects of delay-jitter, packet loss, and bandwidth variation. These principles will be studies within the context of the design of an adaptive videoconferening system. We demonstrate how the data management techniques can be applied and how well they are likely to perform by presenting the results of a recent Internet performance study.
