H.323 is part of a larger series of communications standards that enable videoconferencing across a range of networks. Known as H.32X, this series includes H.320 and H.324, which address ISDN and PSTN communications, respectively. It is therefore necessary to understand the worst-case scenarios in order to minimize the range of protocols needed. Dynamic protocol adaptation is likely to be necessary which will require logic to map particular combinations of requirements to particular mechanisms. Standardizing the way that applications define their requirements is a necessary step towards this.
Classification is a first step towards standardization.
H. Schulzrinne, A. Rao, R. Lanphier. April 1998 Open standard aims to provide an extensible framework to enable controlled delivery of real-time data, such as audio and video. This document presents the issues facing streaming media caching. Streaming media caching refers to the process through which streaming content is dynamically replicated closer to users so as to provide a better viewing experience. A list of RTSP ehancements and open issues are presented.
