METHOD AND DEVICE FOR RANGE OF EQUAL LEVEL NODES IN REAL-TIME P2P STREAM TRANSMISSION NETWORK

摘要

1. A method for ranking equal-level nodes in a P2P network containing a streaming source and a plurality of equal-level nodes, including: receiving from a newly connected to a network equal-level node a request for receiving information material data; determining a delay with respect to the moment of real-time playback of information material data, distributed by the streaming source, from which the specified newly connected equal-level node will have to receive information material data, based on definiteness probability distribution of delay with which for peer nodes receiving data information material distributed by the streaming source; and transmitting to the indicated newly connected equal-level node a list of a plurality of randomly selected equal-level nodes from which the requested data of the information material can be loaded with the expected probability depending on the delay so determined and the throughput of the specified set of randomly selected equal-level nodes, as a result of which the indicated again the connected equal-level node is able to download the requested data with the expected probability th material from a selected one of said plurality of randomly selected for peer nodes with less delay as compared with a delay specific to said newly connected for peer uzla.2. The method according to claim 1, characterized in that the step of determining the delay for the newly connected equal-level node includes: determining the faith
