Introduction to Disruption Tolerant Networking (no audio version) HD

This is a quick tutorial video that contrasts DTN techniques with UDP and TCP, emphasizing the store & forward and custody transfer aspects of DTN that allow data to migrate toward destinations without the need for complete end-to-end connectivity through all intermediate links. The details of TCP and DTN are somewhat simplified to stress the idea that TCP is an end-to-end protocol connection-oriented, while DTN does not require a complete E2E path. No narration is provided in this version, which was designed for looping in a public display.
