Disruption Tolerant Networking

Disruption Tolerant Networking (DTN) is a technology that will provide network services for environments so extreme that no end-to-end path exists through a network. Disruption Tolerant Networking hopes to tackle the problem of communicating in areas where due to various factors normal means of communication have limited success and are unreliable. DTN is aimed specifically at networks which are subject to frequent and long lasting disruptions that destroy or severely degrade normal communications. This paper provides an overview.
