The prospect of the Internet as the fastest growing satellite communication
application coupled with satellite-based multimedia networks has generated a high
level of interest in the performance of TCP over satellite systems
This article presents the network architecture for supporting TCP/IP based services
over satellite.
It discusses the key factors that influence TCP performance over satellite links,
and compares the advantages and disadvantages of low earth orbit and geostationary
satellites.
It is having the feasibility of using Low Earth Orbit satellites to support and
expand the Internet.
This topic gives us brief idea about the TCP behaviour over a Geostationary satellite
system and LEO satellite constellation based on computer simulations, where two
typical Internet applications are taken into consideration : FTP file transfer and
Web browsing
With its ability to cover large area including geographically isolated regions, the
satellite based links have a bright future.
A number of commercial satellite systems have been proposed which target multimedia
services, as illustrated . These systems are based on both geostationary earth orbit
(GEO) and low earth orbit (LEO) satellite networks.
