Disruption Tolerant Network
An advanced technology solutions firm has developed a Disruption Tolerant Networking (DTN) system that will be capable of sending and receiving data reliably even when stable end-to-end paths do not exist. Traditional TCP/IP networks rely on stable end-to-end connectivity - an identifiable path all the way to the destination. In DoD's wireless tactical networks, connectivity is often disrupted by factors such as terrain, weather, jamming, and movement or destruction of the nodes, making it impossible to predetermine a path and halting the flow of message traffic. In contrast, the new system will provide disruption-tolerant content-based access to information. For example, if a user wants to see a map of Baghdad that is no longer available via a network connection to a map server, his request could be satisfied by an accessible node that had previously stored the desired map.
