Data scheduling algorithm for media streaming based on P2P

In order to solve the problem that the data block can not arrive in time in the existing algorithm using pull method,an adaptive data scheduling algorithm is proposed for P2P media streaming.This algorithm can not only choose the server peer automatically according to the transmitting rate and the dynamic feature of P2P networks,but also minimize the quantity of the data block that can not arrive before the playing deadline.Experimental results show that the new algorithm can shorten the data arrival latency of every scheduling period to a certain degree.
