Javed I. Khan@2000

INTERNET BASED SYSTEMS DESIGNThe Internet is a global network of networks

enabling computers of all kinds to directly and transparently communicate and share services throughout much of the world. Because the Internet is an enormously valuable, enabling capability for so many people and organizations, it also constitutes a shared global resource of information, knowledge, and means of collaboration, and cooperation among countless diverse communities.

INTERNET BASED SYSTEMS DESIGNThe Internet is more important in what it enables

than what it is; more phenomenon than fact. Yes, the Internet is networks, software, computers and other technologies; but more so, it is a catalyst of change, a new mass medium, a culture, a mind warp, new things never before imagined.

NOTES: Lines between institutions and aggregation points or NAPs represent the configured bandwidth of their connection to the vBNS.The bandwidth of the actual circuits may be greater than shown.*These are temporary peering points. Permanent East Coast peering with these networks will take place at NGIX-E as soon as it is operational.

Applications & ServicesINTERNET

ENGINEERINGThe real story of the Internet excitement is however is the new genre of systems and applications developed on it.

The Internet offer access to data, graphics, sound, software, text, and people through a variety of services and tools for communication and data exchange:

�Remote login (telnet)

� File transfer (ftp)� Electronic mail (e-mail)� News (USENET or network news)� Hypertext (WWW)� Platform independent computing (Java)� E-commerce, Digital Library, Online Banking� Virtual University, Tele-medicine

Trends• Software Industry is the biggest and fastest growing

industry in the world with an expansion rate approaching 15% annually.

• In 1996, Intranets became the fastest growing commercial application on Internet.

• At one point of this gold rush, Netscape was valued at 6.7 bil lion, before it earned a single dime. There will be many more surprises and tears and joys.

Satellites

• At present, there are at least 111 plans for multimedia satellit e systems involving 528 geo-stationary satell ites, 874 low earth orbit satellites and 161 middle earth orbit satellit es. The plans come from some 69 existing or new venture satellit e operators. Most have not revealed the expected capital costs of their projects. However, those that have, involve capital expenditure of at least US$ 99.5 bil lion.

Wiring of the World!• A mega construction project FLAG (fiber-optic

link around the glob) laid down in 1997 September, the longest man made structure ever buil t, stretches 16,400 miles from England to Japan via Mediterranean sea, Indian and the Pacific oceans.

• A yet bigger undersea cable (23,600 miles) SeaMeWe3, linking Europe with Asia, wil l be operational by 2012.

Finally..• Meganet will gradually transform itself from a

network of networks into a system of systems. Each system or subnetwork will link groups with shared personal and professional interest in a vastly expanded version of the current Internetwork.

• How fast? The propellant will be technology, economy and polit ics.
