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.
A method for enabling sharing of content files among nodes of a peer-to-peer (P2P) network, the P2P network comprising a plurality of sub-networks, each sub-network including a respective plurality of nodes capable of storing content files, wherein each sub-network has associated therewith a corresponding hash table for indexing the content files stored in the nodes of the sub-network, portions of the hash table being distributed among at least some of the nodes of the sub-network, and wherein, for each content file stored in at least one node of the sub-network, the hash table comprises a corresponding node list of the sub-network nodes which store the content file, the method comprising:
A P2P network comprising a plurality of sub-networks, each sub-network including a respective plurality of nodes capable of storing content files, wherein each sub-network has associated therewith a corresponding hash table for indexing the content files stored in the nodes of the sub-network, portions of the hash table being distributed among at least some of the nodes of the sub-network, and wherein, for each content file stored in at least one node of the sub-network, the hash table comprises a corresponding node list of the sub-network nodes which store the content file,
A non-transitory computer readable storage medium storing software executable by a node of a P2P network, the P2P network comprising a plurality of sub-networks each one including a respective plurality of nodes capable of storing content files, wherein each sub-network has associated therewith a corresponding hash table for indexing of the content files stored in the nodes of the sub-network, portions of said hash table being distributed among at least some of the nodes of the sub-network, wherein, for each content file stored in at least one node of the sub-network, the hash table comprises a corresponding node list of the sub-network nodes which store the content file, and wherein each node of the sub-network listed in the node list corresponding to a content file is associated with localization data providing an indication of the localization of the node within the sub-network, the software comprising instructions that, when executed by a computer, perform:
