Currently some P2P video-on-demand patterns using the corresponding technique to adjust and monitor network peer state, effectively reduce the multilayer peer forwarding delay, so as to ensure that the system has good stability and expansibility, but in response to the sudden resource request can not guarantee that the system load balancing. This paper presents a new P2P streaming media VOD system based on window, using a resource reservation mechanism for load balancing algorithm which can realize video server in each media stream between the rational allocation, give full play to the peer load capacity. The simulation shows that the system is able to respond to sudden resource request, and has high bandwidth utilization, effectively improves the performance of the system.
