Abstract

P2P streaming applications develop quickly with the enhancement of PC's performance and network bandwidth.In this paper the system model and the maximum data transmitting rate of P2P streaming system were studied.We presented a system model of P2P streaming system under stable state

which could capture the characteristic of the system by a few parameters.The maximum data transmitting rate of the stable system was derived and proven

and a centralized algorithm named WFSOT was designed to organize nodes into an overlay quickly which could support the maximum data transmitting rate and allocate nodes' practicable bandwidth.At last

we discussed several aspect of the WFSOT algorithm

especially the node's depth in the overlay topology.
