  1. Next Generation InternetM. A. Rahimi, VPNorthwestern University

  2. Outline • Basic Internet Concepts • Development of the Commodity Internet • National Networking Initiatives • Implications

  3. Information Highway • “We must build the second generation high speed Internet ... 1,000 times faster than today’s Internet…” • “ …transmitting information to school children… at the speed of light…”

  4. Digital Coding • Two symbol alphabet 0 1 • Binary ideal for electronics • Binary alphabet can encode any information

  5. Data • ASCII uses 7 bits • 1010111 is letter W • 1110111 is letter w

  6. Flowers

  7. Red, Yellow and Purple Flowers

  8. Multimedia Requirements (No Compression) • Voice[8,000 samples X8 = 64 Kbps] • Compact disk[44,100 samples per second X 16 bits X 2 = 1.41 Mbps] • Super VGA monitor [1024H X 768V X 8 bits = 6.3Mb] • Black and white TV [360 H X 288 V X 1 bit X 30 f/sec = 3.1Mbps] • HDTV [1280 H X 720 V X 8b/color X 3 colors X 60 f/sec = 1.33Gbps]

  9. Inter-networking Ethernet LAN Router Token Ring LAN

  10. Ethernet LAN Router WAN Router Token Ring LAN

  11. NU Illinois Chicago Michigan CIC-NET CICNet NSFNet

  12. Technology Forces • Information Representation • Digital Multimedia (New Media) • More for less/better • Information Sharing • Internet • Growing/not better

  13. Convergence: Applications and Industries • Voice/Telephone Industry • Sound/Music and Entertainment • Video/Television and Entertainment • Data/Computer and Business Application

  14. Present Internet Inadequacies • 45 Mbps backbone • 1.54 Mbps most locations • Unpredictable availability • Unpredictable delay • Lack of quality of service • Best effort service

  15. Response to Internet Commercialization

  16. International

  17. Internet2 and NGI • Internet2 • University-led • Research and education • Business and Industry partners • Government Support • Next generation internet • Federal agency-driven • Research support • Agency mission-critical applications

  18. I2/NGI Requirements Research/Science Teaching/Learning Electronic Commerce Entertainment Healthcare Etc. Predictable Quality of Service

  19. FUTURE • NGI will be in commercial use in three years • Necessary standards will be established • Bandwidth will be plentiful • New Challenges • Tools • Personnel • Product and Services • Realignments • Customers

  20. Industry Example • Higher Education • Core Business • Learning • Discovery

  21. Technology Forces Education/Learning • Massive Federal, State and Private Funding for Networking • Better and Cheaper Equipment • Capable tools • Expanded library of resources • Expanded shared learning experiences • New Generation of Technology Savvy Students

  22. Redefinition of Higher Education Industry • For-Profit Higher Education • Redefinition of Boundaries with other industries

  23. Effective Learning • We learn by doing • Do then listen or read • We learn from personal failure followed by success • Try, fail, improve, … and learn • We learn from doers stories • We learn general principles from cases

  24. Technology Support for Effective Learning • Digital Libraries • On-line Experts • Simulation/Games • Collaboration Environment • Tracking and Evaluation

  25. Higher Education Industry Challenges • Make Learning more effective regardless of form • Shift resources from support of old to new paradigms • Improve decision time • Eliminate artificial divide between practice and instruction • Provide a range of expert teachers otherwise unavailable • Shift emphasis from studying to doing • Extend to new markets • Many teachers for each student
