A Multi-channel End System Multicasting Scheme on P2P Cluster Overlay

In the last decade, more and more media data are produced and shared over Internet. To send data on Internet, casting techniques are commonly used. Attempting to provide scalable applications, many approaches of end system multicast (ESM) have been recently designed over peer-to-peer (P2P) overlays. Cluster overlay is one of scalable P2P overlays in which peers are organized into groups and are not aware of the whole system. In this paper, we address a multi-channel end system multicasting scheme based on cluster overlay. Each multicast group is called a channel. Peers can switch from one channel to another. Super peers in cluster overlay manage peers and channels transferring in its cluster. Data duplicating and forwarding are carried out by peers. Heads of the cluster overlay help peers to find nearby peers who have joined in the channel in-demand to speed up channel switching.
