Abstract:
1. A method for transmitting a live media stream in peer-to-peer (P2P) networks, suitable for a server transmitting a live media stream to a plurality of nodes under a multicast tree, comprising: calculating a reliability of each of the nodes according to an accumulated on-line time of the node and a number of child nodes that are able to be supported by the node by the server; rearranging the nodes according to the number of child nodes and the reliability of each of the nodes by the server to establish an ideal reliable multicast tree, wherein the nodes are arranged in a descending order according to the reliabilities of the nodes in the ideal reliable multicast tree, and the nodes at upper level of the ideal reliable multicast tree has greater reliability; and adapting a location of each of the nodes in the multicast tree in sequence in a descending order according to the reliability of the node by the server, so a level difference between an adapted level of the node in the multicast tree and a level of the node in the ideal reliable multicast tree is the smallest.
