Abstract(in English) | Recently, video conferencing systems based on Peer-to-Peer (P2P) networking technology have been widely deployed. However, most of them can only support up to a dozen of participants. In this paper, we propose a novel method to construct and manage a P2P network for scalable and smooth video conferencing. First, a hierarchical network is eventually constructed as new peers join a conference. Then, the tree topology is dynamically reorganized taking into account the heterogeneity of the available bandwidth among peers and their degree of participation so that, those participants, i.e., peers that can have many child peers and/or often speak are located near the root of the tree. As a result, the delay from speakers to other participants is reduced. When a failure occurs, the tree is recovered through local interactions among peers. Through simulation experiments, we verify that our method can offer smooth video conferencing for 1000 participants where the delay among speakers is about 40 msecs for 10 speakers to 70 msecs for 500 speakers. |
