Tree-Mesh Based P2P Streaming Data Distribution Scheme

This paper presents the design of a novel P2P live streaming policy, tree-mesh based P2P Streaming Data Distribution Scheme(TMDS). Both the tree-based and the mesh-based structures have respective flaws while distributing the media data. The tree-based structure is highly vulnerable, so it is very suitable for the stable environment in small scale. And the mesh-based structure is quite stable, and can guarantee certain grade of service under the large-scale environment, but its costs of control are bigger, and also creates heavy load to the network. However TMDS can effectively solve these problems, and take advantage of their merits. Confirmed in the simulated environment, TMDS can: improve the quality of service; decrease the costs of system control, lighten the burden on the network; relieve the load on the transmitting end, enhance the stability of the system.
