Abstract: Disclosed is a peer to peer (P2P) network system in the present specification. A peer activity management server (PAMS) of the P2P network system receives inquiry whether the PAMS controls a peer from another PAMS or receives status information of the peer or service use or content of the peer from the peer or another PAMS. Further, the PAMS determines whether the peer is controlled based on the inquiry by the PAMS or updates a peer list based on the service use or content of the peer. In addition, the PAMS transmits the status information of the peer included in the peer list to an overlay management server or transmits the service use or content of the peer to a user management server.

Abstract: PURPOSE: An apparatus for controlling peer-to-peer and a method for controlling transmission overlay are provided to enhance the transmission quality of contents by generating stable and efficient P2P(Peer-to-Peer) overlay. CONSTITUTION: A peer registration unit(210) registers plural kinds of peer information, and an overlay generating unit(220) receives an overlay generation request of desirable contents from a request peer among the plural peers. The overlay generating unit generates not only a P2P overlay based on the information of a network to which plural peers are connected but also the plural kinds of peer information. The overlay generating unit considers the P2P overlay to provide the request peer with the connection information for receiving desirable contents.
