some highly selective internet history Presentation Transcript

  • 1. some highly selective internet history
  • 2. with apologies to the many key people i left out
  • 3. benjamin black b@b3k.us
  • 4. part 1: packet switching
  • 5. Paul Baran
  • 6. RAND
  • 7. 1960-1962
  • 8. On Distributed Communications
  • 9. communications networks
  • 10. surviving nuclear war
  • 11. packet-switching
  • 12. 1965
  • 13. Donald Davies
  • 14. 1962
  • 15. Leonard Kleinrock
  • 16. Information Flow in Large Communication Nets
  • 17. theoretical basis for packet- switching
  • 18. packet-switching
  • 19. invented 3 times 3 places 3 reasons
  • 20. we are on the right track
  • 21. 1969
  • 22. ARPANet
  • 23. part 2: ip
  • 24. Vint Cerf
  • 25. Bob Kahn
  • 26. 1973
  • 27. tcp/ip
  • 28. simple & open
  • 29. separation of concerns
  • 30. ip - global routing
  • 31. tcp - reliable delivery
  • 32. decoupled from hardware
  • 33. application presentation COMPLEXITY session transport network data link physical
  • 34. independent administrative domains
  • 35. federated
  • 36. addressing routing policies
  • 37. “network of networks”
  • 38. part 3: protocol wars
  • 39. meanwhile, outside academia...
  • 40. explosion of communication demand
  • 41. explosion of communication protocols
  • 42. mainframe & mini
  • 43. sna decnet
  • 44. telco
  • 45. x.25 frame relay atm
  • 46. pc
  • 47. ip ipx/spx appletalk ethernet ...
  • 48. complexity down the stack
  • 49. expensive (opex & capex)
  • 50. upgrades mean forklifts
  • 51. proprietary incompatible
  • 52. no value-add for protocol proliferation
  • 53. what we needed:
  • 54. simple & open
  • 55. separation of concerns
  • 56. decoupled from hardware
  • 57. federated/ hierarchical
  • 58. ip
  • 59. now:
  • 60. ip over *
  • 61. ethernet frame relay tdm ...
  • 62. * over ip
  • 63. ipsec and ssl vpn voip web email ...
  • 64. part 4: partly cloudy
  • 65. cloud computing 2008
  • 66. packet-switching 1968
  • 67. it won’t take 40 years this time
  • 68. less than 10
  • 69. we can expect:
  • 70. wild proliferation of protocols
  • 71. complexity will move up the stack
  • 72. ...into the apps.
  • 73. and then...
  • 74. rapid convergence of protocol
  • 75. Baran’s diagrams
  • 76. apps for the cloud will follow these models
  • 77. winning protocol features?
  • 78. simple & open
  • 79. separation of concerns
  • 80. decoupled from hardware
  • 81. federated/ hierarchical
  • 82. [this slide intentionally left blank]
