DEVICE FOR CONNECTING PEER-TO-PEER COMMUNICATION CONSIDERING NAT TYPES AND METHOD CONNECTING PEER-TO-PEER COMMUNICATION USING THE SAME

摘要

According to the present invention, a method for connecting peer-to-peer (P2P) communication, which allows a device to connect P2P communication in a network address translator (NAT) environment, comprises the steps of: considering a distribution of a network address translator to explore a type of a network address translator to which clients belong; and establishing a P2P connection according to the type of the network address translator of a node to which clients to perform P2P communication belong, and applying a P2P connection algorithm according to whether information of the node to which the clients belong exists to perform the P2P connection.
