Introduction
DD1000i is an integrated network device that enables unidirectional data flow and physical network separation using optical technology. The device consists of a hardware Data Diode containing an optical fiber with a transmitter on one side and a receiver on the other. Surrounding the Data Diode are two proxy servers, enabling efficient and reliable information transfer from the source network to the destination network.
The proxy server connected to the source, or Upstream, network provides services translating bidirectional communication into a unidirectional protocol that can be transferred through the Data Diode hardware. The proxy server connected to the destination, or Downstream, network receives and recreates the original data before sending it on to the intended receiver.
The integrated proxy servers facilitate architecture design and cause minimal impact on existing systems while providing the means to take control of the information flow between security domains.
