Today's networks mirror their electric telegraph and telephone forebears with working practices, building/facility locations dictated by a copper past. Many of the latest optical networks still utilise old planning and design rules, but Transparent Optical Networks offer new opportunities to break the legacy with direct links between countries, islands, cities, towns and villages. They also offer future proof solutions devoid of 'bandwidth blocking' electronics, and very often, do not require optical amplification. The attendant energy demands and reliability risks associated with electronic transmission and switching are also displaced by 'optical only signals' of a hybrid (analogue-digital) form. The operational opportunities and economic gains of TONs combined with non-linear optics cannot be overstressed as they eclipse anything and everything that has gone before.

Clear Sighted Transparency - Transparent Optical Networks Presentation Transcript

  • 1. Clear Sighted Transparency Peter Cochrane cochrane.org.uk ca-global.org COCHRANE a s s o c i a t e sThursday, 5 July 12
  • 2. Some things are inherently complex... ...and some things are made complex by us!Thursday, 5 July 12
  • 3. Networks of all kinds naturally exhibit complexity ...of interaction, behaviours and outcomes!Thursday, 5 July 12
  • 4. Networks of all kinds naturally exhibit complexity ...of interaction, behaviours and outcomes! Interconnection of yeast proteinsThursday, 5 July 12
  • 5. Complexity rapidly leads to non-linearity... ...with emergent behaviours...and we have no real idea what is going to happen!Thursday, 5 July 12
  • 6. Thursday, 5 July 12
  • 7. We have no generalised math framework for dealing with non-linearity...and it may be fundamentally beyond our capacity!Thursday, 5 July 12
  • 8. Our systems and networks will increasingly surprise us if we continue on the current trajectory !Thursday, 5 July 12
  • 9. Although we fully understand layered complexity does notsolve the problem, we mostly continue to build more layers inthe hope that it might...Thursday, 5 July 12
  • 10. Axiom: We are building a global nightmare of over-complex systems at a computing, networking, fixed, mobile, machine and human level !Thursday, 5 July 12
  • 11. Economic and trading markets are prime examples of uncontrolled and misunderstood complexity!Thursday, 5 July 12
  • 12. This is not ‘rocket science’, but it is complexity compounded by greed.......Thursday, 5 July 12
  • 13. Digital Failures •Always abrupt •Mostly avoidable •Often caused by people •Unanticipated mechanisms •Increasingly life threatening •Dominantly very expensive •Reputationally damaging/fatalThursday, 5 July 12
  • 14. te ca di is ra th rk e f o st h o tw u c e m u n n e m e ca W as th e m sw f ro aThursday, 5 July 12
  • 15. Strange attractors that bring down networks today... .. ...and tomorrow...Thursday, 5 July 12
  • 16. Strange attractors that bring down networks today... .. ...and tomorrow...Thursday, 5 July 12
  • 17. Strange attractors that bring down networks today... .. and tomorrow...Thursday, 5 July 12
  • 18. Dumb industry solutions like MPLS, FTTC, +++ are a result of unthinking short termismThursday, 5 July 12
  • 19. Confusion is rife, complexity growing, and a wireless future can’t do it all... .. everyone of these needs a transparent optical fibre connectionThursday, 5 July 12
  • 20. If we started from a clean sheet: - 180km between repeaters not 40km - 30k people instead of 160k - 60 switches not 7000 - Gbit/s not Mbit/sThursday, 5 July 12
  • 21. Fibre rich networks instead of fibre sparse - no TPON, GPON, BPON, XPON... - PONS made sense when fibre was 30p/m - But now it is 1p/m they are irrelevant and far too complex - They are also bandwidth limiting - A ‘dog’ to manage - And reduce reliabilityThursday, 5 July 12
  • 22. By the same token say goodbye to blown fibre...Thursday, 5 July 12
  • 23. WDMA instead of TDMA... ...amplification instead of regeneration...Thursday, 5 July 12
  • 24. IP over WDM...Ethernet...Thursday, 5 July 12
  • 25. Remove coding to reduce latency, lower cost, improve reliability and improve performance... - Compressing signals to save bandwidth is old thinking - Bandwidth is cheap and near infinite - Coding is expensiveThursday, 5 July 12
  • 26. We have to leave this legacy behind...Thursday, 5 July 12
  • 27. We need to push complexity to the periphery and keep the network ‘essentially simple’...Thursday, 5 July 12
  • 28. If we do not, this world will not be realised in the way we would like!Thursday, 5 July 12
  • 29. We can only . .. ...w hat the futu re h olds . ..Thursday, 5 July 12
  • 30. But we do know it will be mobile and it will eat bandwidth, lots of bandwidth... A transition of < 70 yearsThursday, 5 July 12
  • 31. The expectation is anything and everything, anytime, anywhere, any format...instantaneously! IP over WDM...Ethernet...Thursday, 5 July 12
  • 32. And this has to be global... ...to be reliable and resilient, it will also be relatively dumb !Thursday, 5 July 12
  • 33. Thank You www.cochrane.org.ukThursday, 5 July 12
