ADDING INTELLIGENCE TO INTERNET THROUGH SATELLITE BY SHRIKANTH N nshrikanth050@gmail.com
CONTENTS • Introduction • Current trends • Architecture design • Data Flow diagram • Application domain • Research and development • Conclusion • Future of technology • Bibliography
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.
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 IDS Data Flow Diagram
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.
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.
FUTUREOFTECHNOLOGY • 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
