Abstract

An exemplary method of one way transmission of information is provided, the exemplary method steps preferably include partitioning a portion of each network device along a transmission path (based on a configuration of a source adaptive translation device), to form a source dedicated one way transmission path, analyzing source customer supplied information received by the source adaptive translation device to discern the source supplied information format, mapping the source discerned supplied information into a first synchronous transport signal using the source adaptive translation device, transmitting the first synchronous transport signal across the source dedicated one way transmission path, receiving the first synchronous transport signal at a destination adaptive destination device, and remapping the received first synchronous transport signal back into the discerned source supplied information using the destination adaptive translation device.

mapping the source discerned supplied information into a first synchronous transport signal using the source adaptive translation device, the first synchronous transport signal including a video encapsulation or file encapsulation of the supplied information;

transmitting the first synchronous transport signal across the source dedicated one way transmission path;

receiving the first synchronous transport signal at a destination adaptive destination device; and

remapping the received first synchronous transport signal back into the discerned source supplied information using the destination adaptive translation device, wherein the source dedicated one way transmission path communicates with the source adaptive translation device on a proximal end of the source dedicated one way transmission path, and with the destination adaptive translation device on a distal end of the source dedicated one way transmission path.
