    • Total 1,114 M
    Source http://www.internetworldstats.com/ No. AM Europe Asia Latin Am Africa Mid East Oceania 16.9% total penetration
  • 10. Technology Shapers
    • Internet uses any communication service (IP on everything!)
    • IP carries anything digital
    • End/End Principle (neutrality and user freedom)
    • Radio supplies mobility
    • Fiber/Cable/DSL supplies speed
    • Broadband (choice, symmetry)
    • IPv6 supplies address space
  • 11. IPv4 runout diagram (Geoff Huston) http://www.potaroo.net/tools/ipv4/index.html
  • 12. Internet Traffic Statistics
    • HTTP downloads include traditional text and images represent 45% of all Web traffic.
    • Streaming video is 36%
    • Streaming audio is 5%
    • YouTube is 20% of all HTTP traffic and thus nearly 10% of all Internet traffic
    • Source: Ellacoya, June 2007
  • 13. Socio-Economic Effects of Internet
    • Information Consumers are becoming Producers
    • Democratic access to the world’s information
    • “ Internet is for Everyone” – Internet Society
    • New educational alternatives and outlets
    • New business models (value add, low digital media costs)
    • Risk factors (spam, viruses/worms, social abuse, misinformation, fraud)
    • Innovation at the edge (e.g. wikipedia)
    • Localization (information, interfaces, cultural styles)
  • 14. Mobility and Mobiles
    • 2.5 Billion Mobiles and counting
    • Short Message Systems
    • Payment systems
    • Innovative interfaces (challenges!)
    • Navigation systems
        • GPS, Galileo, Google Earth/Maps,…
    • Geo-location based services
  • 15. Internet-enabled Devices
  • 16. Internet-enabled Devices
    • Programmable – Java, Python, etc.
    • Examples:
    • WebTV, Personal Digital Assistants, Mobiles,Video games, Picture Frames, Washing Machines, Surf Board!
    • Refrigerator (and the bathroom scales)
    • Automobiles (Japan, Germany)
