This paper presents studies for the end-to-end QoS of IP over integrated terrestrial and Next Generation Satellite Network (NGSN) using FTP. We compare between LEO and GEO satellites constellations for the QoS parameters (i.e. delay, jitter, loss rate and throughput) of file transfer from a remote server in London and a remote client in Boston. We model the file transfer with multiple connections and file size variation according to Exponential and Pareto distributions respectively. We create the scenario with error model to simulate transmission loss environment using the NS-2 simulation software. A Differentiated Services (Diffserv) queue interface is placed in the server side to regulate the traffic flows across the narrow bandwidth of the satellite links. The results showed the performance evaluation and presented a good comparison of the QoS parameters involved in the data transfer across LEO and GEO satellites systems.
