Audio-Video Conference Systems Research Based on P2P and Multicast

P2P (Peer to Peer) technology is a network technology which is based on equality. Use of P2P technology in the wide area network to transmit multimedia data, each node can provide resources as sever, so it can improve transmission efficiency. However, in the LAN, multicast data can be simultaneously sent to multiple recipients, so it has more advantages, and can reduce the bandwidth, greatly improving communication speed. Therefore, this paper presents the multicast technology combined with the P2P technology, giving full play to the strengths of both technologies. It can service video conference system better.
