This paper research the transport control scheme for satellite networks. The special characteristics make TCP protocols incapable of providing satisfying service for satellite networks. We analyze the performance of hop-by-hop and end-to-end transport under Bernoulli loss model. Then we propose a novel protocol based on hop-by-hop acknowledgment against the traditional end-to-end TCP for satellite networks, which uses ACK associated with NACK together, allows out-of-sequence packet transmission and has the capability of re-routing in arbitrary node. Both theoretical and simulation results showed that hop-by-hop communication scheme outperforms TCP under highly error prone, multi-hop and long delay conditions.
