There’s a lot of great things going on with the continuing evolution of Interplanetary IP into IETF’s Delay-Tolerant Networking group into a DARPA BAA on Disruption-Tolerant Networking (already closed on 9 July, unfortunately).

Proposers Day Announcement – Disruption Tolerant Networking (DTN)

The Disruption Tolerant Networking (DTN) Program will develop and field technology that will provide network services when no end-to-end path exists through the network.  The primary goal is to provide disruption tolerance by organizing information flow into bundles.  These bundles will be routed through an ?intelligent? DTN network that can manage the delivery of the bundles.  This method will allow messages to pass through the network with successive responsibilities, rather than the traditional end-to-end acknowledgement scheme.  DTN will result in the opportunistically leveraged connectivity and the use of multiple routes while relieving the delivery node of final acknowledgement.

The second goal of DTN is to provide dynamic network naming and routing.  This method uses a late-binding of bundles (or packets) technique to specific nodes or delivery path.  This avoids forcing all parts of the network to be aware of all other parts of the network.  The result will be a network that matches the tactical unit deployment needs for mobility and stealth.  

The Proposers’ Day Workshop will be held on 21 January 2004 at the George Mason University
