PEER-TO-PEER CONTROL DEVICE AND TRANSMISSION OVERLAY MANAGEMENT METHOD
First Claim
1. A peer-to-peer (P2P) control device comprising:
- a peer registration unit configured to receive peer registration requests from a plurality of peers which want to receive contents, and register information regarding the plurality of peers; and
an overlay generation unit configured to receive an overlay generation request of desired contents from a requesting peer among the plurality of peers, generate a P2P overlay by using the information regarding the plurality of peers and information regarding networks to which the plurality of peers are connected, and provide information regarding a connection according to which the desired contents can be received to the requesting peer with reference to the P2P overlay.

Abstract
A peer-to-peer (P2P) control device receives peer registration requests from a plurality of peers which want to receive contents and registers information regarding the plurality of peers, and receives an application service and contents registration request from at least one contents server providing contents and registers the information regarding the application service and contents. When the P2P control device receives a request for generating an overlay of desired contents from a requesting peer, it generates a P2P overlay, a logical path along which contents are to be transmitted to the requesting peer, by using the registered information regarding the plurality of peers, information regarding a network to which the plurality of peers are connected, and information regarding the application service corresponding to the desired contents, and delivers the connection information to the requesting peer with reference to the P2P overlay.

11. A method for controlling a peer-to-peer (P2P) overlay for a logical transmission of contents by a P2P control device, the method comprising:
-
receiving peer registration requests from a plurality of peers which want to receive contents and acquiring peer information regarding the plurality of peers; receiving an overlay generation request including a contents identifier of desired contents from a requesting peer among the plurality of peers; generating the P2P overlay by using the peer information regarding the plurality of peers and network information regarding networks to which the plurality of peers are connected; and transmitting connection information of a counterpart to be configured to be connected to at least one target involved in the P2P overlay with reference to the P2P overlay. - View Dependent Claims (12, 13, 14, 15, 16, 17)
