Adaptable, On-demand Networking

Raytheon BBN’s Disruption Tolerant Network (DTN) reliably advances wireless network traffic despite hostile conditions, jamming activity, or moved or damaged nodes. While traditional IP networks rely on end-to-end connectivity--which means data can be sent only when there is an identifiable path all the way to the destination-- DTN continues to advance data even when there is no complete, identifiable path to the destination.

Opportunistic Communication

Raytheon BBN’s DTN uses episodically or intermittently available links to communicate opportunistically. In the DTN, information is organized into bundles rather than packets and routed through intelligent “custodians” that augment traditional routers. These custodians advance the bundles to the next node on the way to their destination.

Reliable Communication in Unreliable Environments

Raytheon BBN’s DTN uses a variety of communication nodes, such as wireless, satellite, vehicle-mounted, and unmanned aerial vehicles, to continuously advance message traffic even when there is an obstacle in the path that would stop traffic on a traditional network. The result:

• The network continues to function reliably in the environments where communications are most challenging and most critical
• Message traffic continues to flow despite geographic or structural obstacles or malicious disruptions
