This software models the Delay Tolerant Link State Routing protocol. It runs inside the QualNet network simulator, and allows injecting of external bundles when running in emulation mode. It leverages QualNet’s library of networking protocols and JPL’s CCSDS models.

The software analyzes the impacts of different Delay Tolerant Networking (DTN) routing protocols for NASA missions, assisting NASA network designers who wish to use DTN protocols. It is compatible with Windows, UNIX, Linux, and MAC platforms, and requires the QualNet simulator.
