Packet signaling for systematic coding schemes with arbitrary data-to-repair-packet connection setups

We consider the introduction of three different methods to signalize which data packets are used to generate each repair packet in systematic coding schemes employing flexible connection setups: a first one based on a mask, a second one on explicitly pointing out the links between the two packet streams, and a third one on sharing the signaling load between both flows. These methods have been evaluated in terms of the bandwidth required to put them into practice. The evaluation results show that the explicit method introduces less bandwidth, whereas the one sharing the load handles it more smartly.
