A Delay Tolerant Network (DTN) is a network designed to operate effectively over extreme distances such as those encountered in space communications or on an interplanetary scale. In such an environment, long latency-sometimes measured in minutes, hours or days-is inevitable. However, similar problems can also occur over more modest distances when interference is extreme or the network resources are severely overburdened. DTNs involve some of the same technologies as are used in a disruption-tolerant network but there are important distinctions. A DTN requires hardware that can store large amounts of data. Such media must be able to survive extended system restarts and power loss. This paper presents a multi-copy routing method for DTNs.
