some highly selective internet history

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