Abstract

A mechanism is proposed to notify the link layer ARQ retransmission state information to TCP by the cross-layer information exchange. It can avoid the negative effect of delay variation on TCP due to the link layer ARQ retransmission. The perfectly-persistent selective repeat ARQ is adopted to offer a reliable link to TCP to avoid packet loss in satellite links. It does not require the in order delivery at the link layer, then the delay of waiting for reorder is eliminated. The mechanism is fit for satellite networks with big bandwidth delay product. Simulation results validate that it can greatly improve TCP performance in satellite networks, especially when the error frame rate is high.
