摘要:The described study provides the experimental results and their analysis for selection of the file transfer protocol to be used in the upcoming Meteosat Third Generation Programme requiring sustained dissemination data rate in the range of 300-400Mbps over heterogeneous networks. This dissemination speed cannot be easily achieved with default TCP protocol settings and file transfer applications with significant round trip time (RTT) and packet loss typical to large heterogeneous networks. The designed test lab allowed finding the optimal TCP protocol and file transfer application settings reaching the target data rate at 70ms RTT and 10 -6 packet loss, typical to terrestrial networks. Meanwhile, none of the surveyed applications were able to reach the target data rate at 700ms RTT, typical to satellite distribution networks.
