Abstract

While Network Coding has been extensively studied from a theoretical point of view, the number of practical implementations is still very limited. We have performed an actual demonstration of this technique in a real satellite network, where Network Coding was applied on the streams of a videoconference between two terminals. The design challenges are analyzed along with the main ideas that enabled the proposed protocol to achieve more than 90% of the theoretical gains.
