A method for transmitting data between an origin network and a destination network where each network has a network front end and accepts data conforming to a first protocol and a second protocol respectively. Data is transmitted over the origin network to the front end of the origin network by complying with the first protocol, and then the data is transmitted from the front end of the origin network to the front end of the destination network over at least one primitive network. When an ultimate destination of the transmitted data is not the front end of the destination network, the data is transmitted over the destination network to the destination using the second protocol. When primitive network includes an intermediate node, the data is transferred from the front end of the origin network to the intermediate node and from the intermediate node to the front end of the destination network. To achieve high security, the intermediate node can be electrically isolated from the front end of the destination network when the data is transferred from the front end of the origin network to the intermediate node, and then electronically isolated from the front end of the origin network when the data is transferred from the intermediate node to the front end of the destination network. |
