| Summary: | This paper presents the studies for the end-to-end QoS
of IP over integrated terrestrial and Next Generation Satellite
Network (NGSN) using HTTP web application. We compare
between Big-LEO and EuroSkyWay like satellites constellations
for the QoS parameters (e.g. delay, loss ratio, throughput and
connection duration) of request-response HTTP connections
from a remote server in London and a remote client in Boston.
We model the HTTP request-response with multiple connections
and response files sizes variations. We create the network
scenario with error model to simulate the transmission loss
environment using NS-2 simulation software. A Differentiated
Services (Diffserv) queue interface is placed in the terrestrial
network on the server side to regulate and differentiate the traffic
flows across the narrow bandwidth of the satellite links. The
results showed a good performance evaluation comparison of the
QoS parameters involved in the HTTP web communications
across LEO and GEO satellite systems. |
