INTRODUCTION
Generations of satellites in the Internet
key questions arising in the design of a satellite-based 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).
Contd..
Caching at both ends of the satellite.
Automated monitoring.
Proactive content refreshing.
UTILITY
Efficient internet for homes, business etc.
Availability.
Less login time.
State of the art technology.
No land line phone requirement.
APPLICATION AREAS
Rural and remote areas.
Internet based applications.
Disaster places.
War fields.
SCOPE
Areas with no cable connection.
Fairly decent upload and download speed.
Latency is reducing day by day, suiting
real-time applications.
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.
FUTURE OF TECHNOLOGY
Improving the availability.
A transport and proxy for real-time streaming traffic within IDS.
Improved Security and QoS for all traffic flowing through IDS.
Information mined from warehouse and kiosk databases
Contd..
Future launches:
W3B
KA-SAT
