  1. Fiber Optic Cable Last Mile:Lessons from academia Greg Wood TIA Futures Working Group January 11 2002

  2. Disclaimers • My views alone, not Internet2’s • Not a network engineer • Based largely on Internet2 community experience • No single solution

  3. 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

  4. 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

  5. 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

  6. 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

  7. 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

  8. Some people from whom I stole these ideas • Bill St. Arnaud, CANARIEwww.canarie.ca • Peter Cochrane, Concept Labswww.conceptlabs.net • Steve Corbatówww.internet2.edu
