Other AbstractTCP/IP cannot be used in the satellite network directly because of the characteristics of the satellite links. The Space Communications Protocol Standards (SCPS) has proposed to guarantee the safety of the end-to-end data transportation of the space links; it is the extension for space communication of TCP/IP,especially for the transport protocol SCPS-TP. The architecture of SCPS protocol was analyzed; the technical architecture of SCPS-TP and its key technology SNACK (Selective Negative Acknowledge-ment) were discussed. Focused on SNACK technology, the throughput and link utilization of SCPS-TP SNACK was simulated and compared to TCP. As a result, SCPS-TP SNACK performs much better in terms of throughput, link utilization in wide band, high Bit Error Ratc and long round-trip delay communication environment than TCP, and it is more proper for satellite channel that has big time-delay bandwidth product
