Abstract: A hybrid scheduling algorithm based on clustering is presented. In the algorithm, node resources are divided into cluster head and cluster nodes by clustering method and form a clustering network structure. For the network, data is obtained by push algorithm between cluster heads and heads, while pull algorithm between cluster heads and inter-cluster nodes. Simulations show that the algorithm can increase the speed of data block duplication ,reduce the data propagation delay, reduce the control overhead of streaming system efficiently and improve the degree of continuous playback.
