Disclaimers l.jpg
Disclaimers

  • My views alone, not Internet2’s

  • Not a network engineer

  • Based largely on Internet2 community experience

  • No single solution


Why academia is relevant l.jpg
Why academia is relevant

  • “Discovered” the Web, didn’t they?

  • Demanding users and applications

  • Long-term view

  • Technical foundation

  • Can provide large-scale proof of concept

    • Enterprise

    • Market


Lesson 1 applications matter l.jpg
Lesson 1: applications matter

  • Radical increases in bandwidth=new kinds of applications

  • New kinds of applications provide new business opportunities

  • 100Mbps seems to be an inflection point

  • End-to-end performance is crucial

  • Future applications will require Gbps


Lesson 2 fiber deployment gaining momentum l.jpg
Lesson 2: fiber deployment gaining momentum

  • Long haul fiber optic cable “glut”

  • Regional dark or dim fiber gaining

    • I-Light (Indiana)

    • I-WIRE (Chicago)

    • CENIC ONI (California)

  • Campuses turning to fiber

    • George Washington University (and others)

    • SCinet


Lesson 3 networking realities l.jpg
Lesson 3: networking realities

  • LANs are ahead of the curve

  • OEO is expensive

  • DWDM overwhelms Moore’s Law

  • Evolution of optical switching will be critical


Lesson 4 things change l.jpg
Lesson 4: things change

  • Applications requirements uncertain

  • Control of fiber (or lambdas) allows flexibility

  • Lamba switching on the horizon

  • So, waiting may (seem to) pay off


Some people from whom i stole these ideas l.jpg
