Step based data scheduling algorithm for P2P streaming system
Hao Ren, Jinlin Wang, Jiali You · Computer Engineering and Applications Journal · 2011
Existing data scheduling algorithm makes insufficient consideration to improve data collaboration among peers, which leads to heavy server load in current P2P streaming system.In order to solve this problem,a step based scheduling algorithm is proposed.When there are more than one peer will request same data chunks in one scheduling period,each peer will obtain these chunks in 2 steps.In step 1,each peer will obtain part of chunks cooperatively.In step 2,each peer will share chunks which have been obtained in step 1 with other peers.Simulation shows that the proposed algorithm can enhance data collaboration among peers and make full use of peers’bandwidth resource to transmit media chunks,which im proves system scalability.
