One-Way Transfer Video Routing via GUID Enrichment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
One-way transfer systems for full-motion video routing lack reliability due to unidirectional data transmission, which prevents confirmation of data receipt and processing, and face challenges in routing video streams without knowledge of destination addresses, especially in high-trust environments.
Innovation Solution
The system enriches video stream datagrams with a global unique identifier (GUID) to ensure reliable transmission and routing, even in environments where source devices are unaware of destination addresses, by using a fault-tolerant one-way transfer system that extracts the GUID for proper delivery within the high-trust computing environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-way transfer system is used for video routing, then system security and unidirectional data flow are improved, but reliability and ability to confirm data receipt deteriorate
Solution Approach 1:
The patent applies preliminary action by embedding routing metadata and GUIDs into video stream datagrams before transmission through the one-way transfer system. This pre-packaging of routing information ensures that even without bidirectional communication for acknowledgments, the system can reliably route and track video data packets through the unidirectional channel, effectively compensating for the lack of traditional acknowledgment mechanisms.
2Ease of operation
If source devices have no knowledge of destination addresses, then system simplicity and unidirectional protection are improved, but routing capability and delivery accuracy deteriorate
Solution Approach 1:
The patent introduces an intermediary mechanism where routing metadata acts as a mediator between source devices lacking destination knowledge and the ultimate destination. The metadata embedded in datagrams contains GUIDs and routing information that intermediate systems can use to forward packets without source devices needing to know final destinations, thus preserving both simplicity and routing capability.
Solution Approach 2:
The patent adds another dimension to the routing problem by embedding routing metadata within the video stream datagrams themselves rather than relying on separate addressing layers. This dimensional addition allows routing information to travel with the data through the unidirectional system, enabling delivery accuracy without compromising source device simplicity.
3Adaptability or versatility
If routing metadata is added to video stream datagrams, then routing capability is improved, but data transmission overhead and processing complexity increase
Solution Approach 1:
The patent merges routing metadata with the video stream datagrams by embedding the routing information directly within the existing data structure. This combining approach allows routing functionality to be added without creating separate parallel systems, reducing overall complexity while maintaining routing adaptability through the integrated metadata.

AI summary
The present disclosure describes systems and methods relating to full motion video (FMV) routing in one-way transfer (OWT) systems. The present technology enriches the datagrams of the video stream that are sent from the low-trust side of the OWT system with a global unique identifier (GUID) that is used as an identifier to determine a particular destination on the high-trust side of the OWT system. The enriched video stream is then transmitted through an OWT system that provide high reliability for the enriched video stream. When the enriched video stream is received on the high-trust side, the GUID in the datagram is extracted and used to identify destination addresses for destination devices in the high-trust computing environment. The video stream is then delivered to the destination devices having the corresponding destination addresses.
