<p><P>PROBLEM TO BE SOLVED: To distribute contents over a peer-to-peer network such that the full potential throughput of the network is achieved. <P>SOLUTION: The content distribution method divides the content to be distributed into many small blocks. Each of the content blocks then is assigned to a node, which can be a content-requesting node, a non-content-requesting node or a source node. Content is assigned based on a capacity of the node, where nodes having a larger capacity are assigned a greater number of content blocks and nodes having a smaller capacity are assigned a fewer content blocks. The capacity generally is defined as the upload bandwidth of the node. Redistribution queues are employed to control the throughput of the distribution. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
