Delay Tolerant Networks (DTNs) emerged as a novel architecture to address the challenges in end-to-end connectivity in unexplored networked satellite mission areas. It started in the late 1990s as a discussion on how to extend the Internet into interplanetary space. Objects in interplanetary space are so far apart that the fundamental assumptions underlying the internet architecture at the time wasn’t adequate. They needed a new networking paradigm that embraced delay and disruptions in such environments.
