Beschreibung:
  • Communication over geostationary satellite links is improved by introducing end-to-end Forward Error Correction (FEC) and simultaneous transmissions over two links (channel bundling). The main objective of this work is to investigate to which degree the goodput and the reliability can be enhanced using the mentioned techniques. The performances of the two FEC schemes Reed-Solomon Codes and Random Linear Network Coding are compared. Uncorrelated and correlated packet errors are considered, the latter with a Gilbert-Elliot channel model. Experiments are conducted in a testbed consisting of a single PC with virtual network interfaces to determine the influence of various parameter settings on performance. Results are compared against a scenario with one link offering the same capacity as the two links together. It is concluded that using two heterogeneous links is beneficial for the goodput and losses for generation sizes larger than 20 for three correlated lost packets on average.
