摘要：
The invention provides a server, a method and a system for providing node information for P2P network. A server in a peer-to-peer (P2P) network comprises: a location information storage unit which stores coordinate information indicating a coordinate of each data node in the P2P network in a coordinate system that is created based on communication delays among data nodes in the P2P network; and a node information providing unit which, upon receipt of a request for information on data nodes having a first data item, selects one or more data nodes from data nodes having the first data item based on the coordinate information, and provides information indicating the selected one or more data nodes.
