| Popis: | We developed an analytic characterization of the steady-state throughput of a free-space optical satellite communications (FSOSC) system which includes an ultra-high-speed transmission control protocol for FSOSC (TCP-FSO) and an adaptive- distributed-frame-repetition (ADFR) technique. Our model captures the effects of forward error correction (FEC) on optical transponders, overhead on an Ethernet link-up, error recovery on ADFR, and the congestion/retransmission controls of TCP. We conducted measurements using a testbed system including an FSOSC emulator. Our results validated our model estimates the throughput in FSOSC with sufficient accuracy. The model can estimate approximate throughput even in cases with many packet errors and large delay, for example, a 32% bit-error ratio (56% packet error ratio) and 500 millisecond round trip delay. Throughputs in various FSOSC conditions can be calculated easily with the model. |
