Abstract
A method for enabling sharing of content files among nodes of a P2P network is provided. The P2P network comprises sub-networks each including a respective plurality of nodes capable of storing content files. Each sub-network has an associated corresponding hash table for indexing content files stored in the nodes. The hash table is distributed among at least some of the nodes of the sub-network. For each content file stored in at least one node, the hash table comprises a corresponding node list of the sub-network nodes which store the content file. The method comprises associating each node of the sub-network listed in the node list corresponding to a content file with localization data indicating the localization of the node within the sub-network. The localization data defines a corresponding preferential list of the nodes storing the content file for downloading the content file by a requesting node.
