End-to-End QoS Evaluation of IP-Diffserv Network over LEO Satellite Constellation
In this paper, we present an end-to-end QoS simulation studies on
internetworking of remote LAN and long range communications over LEOIridium
satellites constellation taking SuperJARING network in Malaysia as an
example. A macro level network simulation scenario based on actual network
topology in Malaysia is implemented as Diffserv network model using the
Network Simulator-2 (NS-2). Web traffic (HTTP) is used as the internet traffic
models in the simulation analysis. All simulations are carried out in error-free
and link-loss environment. In error-free simulations, the accumulative network
traffic loads are varied from 20%, 50% and 80% while in link-loss environment
simulations only 20% traffic load is used with bit error rate (BER) varied from
1x10-5, 1x10-4 and 2x10-4. The results show clearly that QoS can be achieved
with IP Diffserv over satellites constellation like Iridium
