Peer-to-peer and network-based multimedia bridging architectures

摘要

Two kinds of multimedia conferencing bridging systems are examined: peer-to-peer and network-based bridging architecture. The investigation shows that the network-based system outperforms the peer-to-peer architecture in saving the bandwidth in the access link as well as within the network especially for audio and video. However, peer-to-peer bridging appears to be optimal for data.
