Some multimedia traffic characterisation and measurement results

The authors discuss traffic characterisation and measurements made of experimental multimedia (including audio and video) traffic on the CAR and PREPARE experimental networks, and the IP pilot service on the UK JANET network. They describe the PREPARE experimental architecture and the proposed SuperJANET architecture. They summarise the characteristics of the various media and some of the architectural issues concerning multimedia conferencing. They present detailed results for measurements of shared files, shared windows, audio and video on the current JANET II network. Finally, they draw some conclusions about the future of multimedia services. >
