METHOD OF ESTABLISHING A CONNECTION

摘要

The invention concerns method of establishing a connection in a peer-to-peer network (160), and a peer, a telecommunication infrastructure comprising the peer-to-peer network (160), and a computer program product to execute said method. The connection is established between a first peer (61 ) in a first address realm of the peer-to-peer network (160) and a second peer (62) in a second address realm of the peer-to-peer network (160). In the peer-to-peer network (160), a network address translation is discovered which prevents a direct connection between the first peer (61 ) and the second peer (62). A third peer of the peer-to-peer network (160) is determined as a relay peer (R). The relay peer (R) relays the connection between the first peer (61 ) and the second peer (62).
