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.
HISTORY (contd..)
 2002: StarBand Communications Inc. and Hughes
offer satellite Internet
 2005: WildBlue's brought its satellite Internet
service to rural areas around US
 2008: Google and HSBC plan to provide cheap,
high-speed net to Africa and other emerging
markets.
 2009: Hughes satellite internet service is available
at US military bases.
CURRENT TRENDS
 Advanced Satellite Internet Modems.
 Secure communications - 3DES Encryption.
 Enforced Quality of Service (QoS).

DATA FLOW
Contd..
 Caching at both ends of the satellite.
 Automated monitoring.
 Proactive content refreshing.
Contd..
IDS issues:
 Throughput balance.
 Missing web pages.
 DNS lookup.
 Fault tolerance.
WORK MODEL
Contd..
BEAM SPOTS OF SATELLITE
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.
Internet on the move
SCOPE
 Areas with no cable connection.
 Fairly decent upload and download speed.
 Latency is reducing day by day, suiting
real-time applications.
STATISTICAL DETAILS
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
