Abstract

The Overcast working process and principles of Cisco based on the PeerCast model were expounded,and the node selection strategy of Overcast system was analyzed,the delay performance of bandwidth priority algorithm was improved and node structure tree was also balanced.The simulation results showed that the performance of this new algorithm was better than the original node selection algorithm.
