Abstract
A method and a system for transmitting a live media stream to a plurality of nodes under a multicast tree in peer-to-peer (P2P) networks are provided. First, the reliability of each node is calculated according to a number of child nodes that can be supported by the node and an accumulated on-line time of the node. According to the number of child nodes and the reliability of each node, the nodes are rearranged in a database to establish an ideal reliable multicast tree. Finally, according to the reliability of each node, a location of each node in the multicast tree is practically adapted in sequence in a descending order, and a relative delay between nodes is weighted and compared, so a level difference between the adapted level of the node in the multicast tree and the level of the node in the ideal reliable multicast tree is the smallest.
