Method for the initiation of a shared computer session

摘要

The method provided is for the initiation of a computer session which is shared by two computers that are connected via internet behind NAT routers so that there is no additional relay server necessary. In contrast to conventional methods which can only connect two computers behind NAT routers via a relay server, there is no need to charge users for the incurring additional traffic. The invention regards a method for the initiation of a computer session which is shared by two computers with the following steps: Manual or automatic start on two computers through a communication software that can exchange arbitrary data via a mutually used rendezvous server. Discovery of the local IP address and of a free port and discovery of the global IP address and port on each side. Transmission of the discovered data to the respective peer via the rendezvous server. Hole punching into the respective opposite NAT. Start of a packet-oriented bidirectional transmission protocol with automatic repeat request.
