1. A data transmission system, comprising at least one data transmission network, one or more client machines linked to said network and one or more server machines which are also linked to said network, whereby each of said client machines is able to be connected at a given moment, via said central server, to one or more of said server machines in order to exchange data with it;

  • wherein said server or client machines do not have means allowing them to receive incoming connections, but each of said server machines includes a client connection means device which allow it to establish a permanent connection with said central server and each of said client machines includes a client connection means device which allow it to establish a temporary connection with said central server, and said central server includes a connection means device which allow the establishment of a bidirectional bridge in order to interconnect a client machine and a server machine with the aim of exchanging data, said bidirectional bridge including a unidirectional gateway which allows data transfer from said temporary connection to said permanent connection and a unidirectional gateway allowing data transfer from said permanent connection to said temporary connection, said gateways mutually self-destructing in a cascading manner if one of the connections is cut, which automatically terminates said bidirectional bridge.
