Delay Tolerant Networking (DTN) is a computer network architecture, seeking to address the technical issues of delayed and disrupted network connectivity. Specifically within the proposal of an Interplanetary Internet, DTN provides networking technologies to copewith the significant delays and packet corruption of deep-space communications. Using DTN, the objective is to achieve successful data delivery, to maximize the link utilization and to address many specific problems of space communication such as high bit error rates, intermittent link connectivity and long transmission delays. This technology enables manifold applications and operations concepts, which are superior to current transmission mechanisms. Focus is put on data delivery and not on timeliness as first criterion.This study aims to identify and proof a suitable scenario to utilise DTN, in particular in the area of LEO and GEO Satellites suchasEarth Observation satellites.The goal is to study how to realise the establishment of the Space Internet around Earth, and to examine and proof the possible benefits thereof. Specifically it should: 1) Examine implementation scenarios for Delay Tolerant Networksfor flexible communication with EO satellites to maximize station utilization and support emergency communication. 2) Proof conceptwith representative simulator and DTN routing configuration generation to devise suitability. 3) Define rollout strategy and roadmap for introduction and Break-even point of investment.
