P2P SEARCH METHOD FOR SEARCH INSIDE FIRE-WALL, AND SYSTEM FOR ENABLING THE METHOD

摘要

A P2P(Peer-to-Peer) search method for searching the inside of a firewall and a P2P search system thereof are provided to rapidly increase the number of peers to share data by permitting search and connection to the peers placed inside the firewall. An information collector(210) transmits an information collection request for collecting information related to the second peer connected to a server in the first peer and makes the server generate/transmit the generated and connected terminal information to the first peer in response to the information collection request. The generated information includes firewall presence information for the second peer. A searcher(220) discriminates the second peers into the peers inside/outside the firewall in the first peer, checks the peers inside the same firewall as the firewall of the first peer, transmits a search request to the peers inside the same firewall, and makes the peers inside the same firewall transmit a search result to the first peer.
