摘要： 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 the content files stored in the nodes of the sub-network. The hash table is distributed among at least some of the nodes of the sub-network. The method comprises, for each content file stored in at least one node of a sub-network, storing in the hash table associated with the sub-network a criticality index providing an indication of the degree of sharing of the content file among the nodes of the sub-network. The method causes a node to cache at least one content file for sharing with other nodes of the sub-network based on the criticality index of the at least one content file.

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.
