ABSTRACT:
A method for caching data in a hybrid peer-to-peer system comprising a plurality of interconnected peer computers is disclosed. The method comprising the steps of establishing (1702) a performance criterion, arranging (1703) the hybrid peer-to-peer system as a plurality of interconnected hierarchical groups of peers by assigning each of the plurality of peers to at least one group as a first function of the performance criterion, and processing (1704) the data into a plurality of hierarchical data partitions. The method thereafter allocates (1705), as a second function of the performance criterion, each said data partition to at least one of the groups, and caches (1706) each said data partition in at least one peer in the corresponding group.
