Abstract: Today networks are designed to reliably transmit traffic such as data from point to point i.e. unicasting, or from point to multipoint i.e. broadcasting. Multimedia places further demands on the network. First of all, multimedia traffic, such as audio or video, cannot tolerate delays in delivery like those tolerable by plain data transfer applications. Multimedia requires that data packets arrive on time and in the proper order at the client side. Real-time protocols and quality of service guarantees addresses this issue. Furthermore, multimedia requires transmitting large amount of traffic over the network and thus uses far more of the networks bandwidth than in case of those basic network operations. Multicasting offers far more efficient way of transmitting such traffic over the Internet than unicasting or broadcasting ever would. The subject of this paper addresses the issue of efficient routing of such multicast traffic.

Abstract: Video conferencing provides real-time video and audio communications; and collaborative computing provides application sharing among desktop users in distributed locations. The combination of video conferencing and collaborative computing represents the key components of the multimedia conferencing applications. The intent of this document is to provide information on technologies necessary for multimedia conferencing applications. This paper is focused on the audio and video compression methods, the ways of data transmission over various types of networks and interoperability standards.
