Reliable Multicast via Satellite: Uni-directional vs. Bi-directional Communication
We investigate reliable multicast communication over satellite networks. We compare a scenario where receivers can use a feedback channel to signal loss to a scenario where no feedback channel is available. We show that the introduction of a feedback channel is the key to allow for bandwidth-efficient, robust and fully reliable multicast communication via satellite.
