INTRODUCTION
Generations of satellites in the Internet
key questions arising in the design of a satellitebased
system:
1) Satellite v/s terrestrial networks
2) Elements of satellite-based Internet link
3) Design issues
HISTORY
1973: Two European computers linked to an
American network.
1996: The first consumer satellite Internet service
went into service
1998: Intel has invested in satellite Internet
businesses
2000: America Online Inc, and Hughes tested a
high-speed satellite Internet service in 16 cities.
CURRENT TRENDS
Advanced Satellite Internet Modems.
Secure communications - 3DES Encryption.
Enforced Quality of Service (QoS).
CONCLUSION
Satellite Internet promise a new era of global
connectivity, but also present new challenges
to common Internet applications.
Further improvements can be made at the
protocol level by extending the current TCP
standard.
