INTRODUCTION o o 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 o o 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. . ) o o 2002: Star. Band Communications Inc. and Hughes offer satellite Internet 2005: Wild. Blue'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 o Advanced Satellite Internet Modems. o Secure communications - 3 DES Encryption. o Enforced Quality of Service (Qo. S).

INTERNET TRAFFIC CATEGORIES

Contd. . Traffic Definition IDS traffic category Web sites popular over long time A Publisher pushed B Automatically identified as hot Web sites C Real-time streaming D Kiosk unicast requests E Semi-real time F

DATA FLOW

Contd. . q Caching at both ends of the satellite. q Automated monitoring. q Proactive content refreshing.

Contd. . IDS issues: o Throughput balance. o Missing web pages. o DNS lookup. o Fault tolerance.

WORK MODEL

Contd. .

BEAM SPOTS OF SATELLITE

UTILITY o Efficient internet for homes, business etc. o Availability. o Less login time. o State of the art technology. o No land line phone requirement.

APPLICATION AREAS o Rural and remote areas. o Internet based applications. o Disaster places. o War fields.

Internet on the move

SCOPE o Areas with no cable connection. o Fairly decent upload and download speed. o Latency is reducing day by day, suiting real-time applications.

STATISTICAL DETAILS

CONCLUSION o o 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 o o Improving the availability. A transport and proxy for real-time streaming traffic within IDS. Improved Security and Qo. S for all traffic flowing through IDS. Information mined from warehouse and kiosk databases
