  2. Who Wants to be a CIO? • Fastest finger---put these in the order of priority: • Campus-wide authentication and authorization • Upgrading campus wiring and hardware • Supporting faculty in the use of technology in classroom and laboratory • Defining a funding model for campus IT

  3. Applications Ted Hanss

  4. YNI time

  5. Technology Adoption Late Majority Early Majority Early Adopters Laggards Innovators Source: Crossing the Chasm, Geoffrey Moore

  6. Music instruction – University of Oklahoma

  7. Office of the Future – UNC, Brown, Penn

  8. Teleimmersion – University of Illinois

  9. Haptic control of instruments – University of North Carolina

  10. All Science is Computer Science

  11. All Science is Comp Science • Infrastructure expectations • Emerging Grid computing environment • NEESGrid • www.neesgrid.org • GriPhyN • www.griphyn.org • Local computing clusters • Storage, data transfer, etc.

  12. Collaboration Services

  13. Collaboration Services • Research, teaching, and learning implications • Growth in international collaborations • Mentoring relationships that span institutions • Infrastructure expectations • Classrooms • Meeting venues

  14. Mobile Computing

  15. Mobile Computing • 802.11a will support streaming video at high quality • 802.11 phones competing with 3G? • Deployment of always connected PDAs • Telemetry information being key to applications

  16. Appliances

  17. Appliances • What are appliances? • Polycoms, sensors, web cams, … • Challenges • How to manage?

  18. Capture and Display

  19. Capture and Display • Capture • Getting to HDTV cheaply • Spatial sound • Voice and motion capture • Display • Auto-stereoscopic • Large plasma displays

  20. Peer-to-Peer

  21. Peer-to-Peer • Despite hype, still very much an emerging area • Most examples given are actually client/server applications • Challenges in management • Gnutella searches consume orders of magnitude more bandwidth than actual data transfers.

  22. .edu ASPs

  23. .edu ASPs • Desire to drive commodity services into the infrastructure • Seeking goals of cost savings, improved reliability, … • Upcoming reports may advocate a “services infrastructure” for the research and education community

  24. Cool Technology I’ve Seen Recently

  25. Cool Technology I’ve Seen … • NCast --- run a video-enabled seminar from a box • Digital Fountain --- “on demand multicasting” • Teleportec --- “heads up display” for videoconferencing

  26. What Ever Happened To …

  27. What Ever Happened To … • Adaptive applications? • Requires end-to-end measurement • Metricom? • Priced too high? Insufficient coverage?

  30. Future Networks –Bigger, Faster, Smarter David L. Wasley University of California

  31. Yes, but • what ever happened to… • LEOS? • Hybrid fiber coax to the home? • QOS? • IPv6? • ATM-over-IP

  32. Wild speculations • Neutrino net - just point and shoot • Detectors the size of the Astrodome !! • Still slower than a modem • Cosmic net • Round trip times are a problem ;-( • Filling the pipe to Andromeda takes 1020 bits • 3x108 meters/sec. - it’s the law! • Even a good lawyer can’t get around that one

  33. Network layer trends • Bigger - everything on-line, all the time • Faster - terabits/sec on single fiber w/in 10 yrs • Smarter - because it has to be • Cheaper? • How much is it worth to you? To business? • Best bet is higher capacity for “constant” dollar • Financial models need to evolve to be rational

  34. Bigger … • WAP in PDAs (e.g. nextgen cellphones) • Miniature IPv6 stack-in-a-matchbox • Monitor operation of equipment, e.g refrig. • Better energy management (e.g. at UCB) • Smart cars • Your “radio” is the wireless hub/router for the car • Can receive and send traffic conditions, etc. • Can it schedule appointments on my calendar and at the garage when maintenance is required… ?-)

  35. Faster • Fiber glut? • Some carriers installing 400-800 strand cables • One strand will carry > 1 terabit/sec. • Will IP be replaced by switched wavelengths? • Optical BGP controls pure optical switches • 55 Mb/s for laptops, classrooms, homes • Cable/DSL box with integrated 802.11a (or better) • Fast mobile IP links • Commuter trains - > 100 mph

  36. Smarter • Roaming • QOS • A few different ‘services’ might be enough • Admission management requires authentication • Network has to participate in stopping abuse • Reverse trace ability (how did the packet get here?) • Automatic blocking at the source • Authentication of all users at the network edge • Must balance privacy and managability

  37. Other possible trends • Rational financial models for network services • Involve the user in cost/benefit decisions • Inter-provider reconciliation • Differential billing based on “distance”? • Always bill the transmitter(?) • The last chance not to send the packet … • Smartcards as access tokens for lots of things • Like phone cards only smarter • Privacy ensured by third party anonymizers

  38. Some campus issues • Issuing and managing digital credentials • Managing access to premium services • Collecting and processing usage data • Continuous enhancement of infrastructure • High speed wireless • Gigabit+ to the desktop • Highly robust infrastructure for critical applications • Outsource all this?

  39. Previous speculations • “The world will only need 4 computers” • “The world will only need 80,000 PCs” • 300 9600 128K 10M 100M is good enough • See also Wasn't the Future Wonderful? : A View of Trends and Technology from the 1930's
