Abstract:
1. An apparatus for transferring data across a single one-way link, comprising: a data transmitter capable of receiving data streams based on two or more different types of transport layer protocols from source platforms and transferring the data streams across the one-way link concurrently; and a data receiver for receiving the data streams from the one-way link and forwarding the data streams to destination platforms, wherein: the data transmitter is configured to assign a channel number to each of the data streams based on IP information of the corresponding source platform and port information of the data transmitter and replace the IP information of the corresponding source platform with the channel number, and the data receiver is configured to map the channel numbers to IP information of the destination platforms and port information of the data receiver, wherein the IP information of the destination platforms remain undisclosed at the source platforms and no IP information is sent across the one-way link.
