| Summary: | 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. |
