A Data Block Priority Based Load Balancing Algorithm for P2P Streaming Media

Abstract

In order to improve the transmission of the streaming media over P2P network, we propose a Data-block Priority Based Load Balancing Algorithm (DPBA) for P2P Streaming Media. H.264/SVC achieves temporal scalability, spatial scalability and quality scalability. DPBA takes into account the quality layer and urgency degree of streaming media data block. The simulation result shows that DPBA can guarantee smooth playing of P2P streaming media. Meanwhile, it reduces the useless packet ratio and the playing interrupt times, thus the playing quality of the streaming media is stable.
