Audio-video conference systems design and implementation base on P2P and multicast

摘要

Using P2P technology in the wide area network to transmit multimedia data, each node can take advantage of resources and improve transmission efficiency. However, in the same LAN, multicast data can be simultaneously sent to multiple recipients, so he has most advantages, it can reduce the bandwidth, greatly improving communication speed. Therefore, this paper presents the multicast technology combined with the P2P technology; give a specific method to achieve a hybrid of live audio and video conferencing systems.
