Patent ID: 8266689

Claim:
A bilateral data transfer system comprising: a first node; a remote terminal client connected to the first node; a second node; a remote terminal server connected to the second node; a first one-way link for unidirectional transfer of first data from the first node to the second node; and a second one-way link for unidirectional transfer of second data from the second node to the first node, wherein the first node comprises: one or more processors; a memory storing a first data sending application, a second data receiving application and a first session managing application; and wherein the one or more processors are configured to execute: the first data sending application for sending the first data to the second node over the first one-way link; the second data receiving application for receiving the second data from the second node over the second one-way link; and the first session managing application for blocking the first data from the second data receiving application and for blocking the second data from the first data sending application, and wherein the second node comprises: one or more processors; a memory storing a first data receiving application, a second data sending application and a second session managing application; wherein the one or more processors are configured to execute: the first data receiving application for receiving the first data from the first node over the first one-way link; the second data sending application for sending the second data to the first node over the second one-way link; and the second session managing application for blocking the first data from the second data sending application and for blocking the second data from the first data receiving application, so that the unidirectional transfer of the first data across the first one-way link and the unidirectional transfer of the second data across the second one-way link are independently administered by the bilateral data transfer system, wherein: the first data comprises a request for data from the remote terminal client; the second data comprises requested data from the remote terminal server; the first session managing application is configured to route the first data from the remote terminal client only to the first data sending application and configured to route the second data from the second data receiving application only to the remote terminal client; and the second session managing application is configured to route the first data from the first data receiving application only to the remote terminal server and configured to route the second data from the remote terminal server only to the second data send application.
