NASA's High-rate Delay Tolerant Networking (HDTN) Network Operations Webinar

When: Tue, 1/27/2026 at 2:00 PM (Eastern Time)

Transmitting data across millions of miles in space presents inherent challenges, including disruptions, long delays, and higher error rates. NASA Glenn Research Center's High-rate Delay Tolerant Networking software offers a significant advancement, providing up to 10 times improvement in data latency and throughput over existing Delay Tolerant Network (DTN) systems, while remaining fully compatible with established protocols. Designed for high-rate optical communications enterprise ground networks, and low-SWaP platforms such as small satellites, HDTN has been rigorously tested and successfully demonstrated in flight. This webinar will provide an overview of HDTN's architecture and highlight opportunities for commercial adoption and integration. Join us to hear directly from the innovators.
