  2. What is netw ork neutrality? 2

  3. What is netw ork neutrality? Technology enables network providers to control applications and content 3

  4. Goals of the Talk • Framework for understanding the debate 4

  5. Goals of the Talk • Framework for understanding the debate • Overview of main positions and arguments 5

  6. Goals of the Talk • Framework for understanding the debate • Overview of main positions and arguments • Relevance for IETF • Impact of potential rules on IETF standards • Potential new work 6

  7. Framew ork I . Proposed Rule 1. Blocking 2. Discrimination a. QoS b. Charging for QoS I I . Proposed Exceptions 1. Security 2. Congestion Management 7

  8. A rule against blocking is at the core of all netw ork neutrality proposals ... • ... may be framed as user rights ... 8

  9. A rule against blocking is at the core of all netw ork neutrality proposals ... FCC Internet Policy Statement, 2005 • "... consumers are entitled to access the lawful Internet content of their choice.“ • "... consumers are entitled to run applications and use services of their choice, subject to the needs of law enforcement.“ • "... consumers are entitled to connect their choice of legal devices that do not harm the network." 9

  10. Scope • Network neutrality rules only protect against blocking • of legal content and applications • driven by network providers‘ interests • Network neutrality debate does not address • proper treatment of illegal content or applications • interference with users‘ Internet use driven by the state 10

  11. Do netw ork providers have an incentive to block? I 11

  12. Do netw ork providers have an incentive to block? • Not always ... 12

  13. Do netw ork providers have an incentive to block? • Not always ... • ... but more often than you would expect: • to increase their profits 13

  14. Do netw ork providers have an incentive to block? • Not always ... • ... but more often than you would expect: • to increase their profits • to exclude unwanted content 14

  15. Do netw ork providers have an incentive to block? • Not always ... • ... but more often than you would expect: • to increase their profits • to exclude unwanted content • to manage bandwidth on their networks 15

  16. If there is an incentive, should regulators care? 16

  17. If there is an incentive, should regulators care? Network neutrality proponents: • Impact on application and content developers • Impact on users • Application innovation/competition, free speech 17

  18. If there is an incentive, should regulators care? Network neutrality opponents: • Only anticompetitive behavior • Role as editors • Need to manage networks • Competition solves the problem 18

  19. If there is an incentive, should regulators care? • ... or „is the Internet different?“ 19

  20. What is the role of competition? • ... or: „are there alternatives to regulation?“ 20

  21. Framew ork I . Proposed Rule 1. Blocking 2. Discrimination a. QoS b. Charging for QoS I I . Proposed Exceptions 1. Security 2. Congestion Management 21

  22. Does the proposed rule prohibit „discrimination“? 22

  23. How does the proposed rule define „non-discrimination“? • ... or „does the proposed rule prevent QoS?“ 23

  24. How does the proposed rule define „non-discrimination“? • treat every packet the same • treat classes of applications the same • users choose QoS, network provides QoS 24

  25. If netw ork providers can offer QoS, w hom are they allow ed to charge for it? • ... or „to what extent does the proposed rule restrict network providers‘ business models?“ 25

  26. If netw ork providers can offer QoS, w hom are they allow ed to charge for it? • nobody • only their own access customers • access customers and application/content developers (but needs to be non-discriminatory) • whomever they want to 26

  27. Framew ork I . Proposed Rule 1. Blocking 2. Discrimination a. QoS b. Charging for QoS I I . Proposed Exceptions 1. Security 2. Congestion Management 27

  28. Does the proposed rule allow blocking/discrimination for security? • e.g., denial of service attacks, viruses, spam 28

  29. Does the proposed rule allow blocking/ discrimination during times of congestion? • ... or „to what extent does proposed rule restrict network providers‘ ability to manage congestion?“ 29

  30. Does the proposed rule allow blocking/ discrimination during times of congestion? • any congestion management is fine • any congestion management is fine, as long as it is disclosed • congestion management needs to be non-discriminatory, if possible • single out specific applications (clearly not o.k) • single out classes of applications (may be o.k.) • give users choice of prioritization (clearly o.k.) 30

  31. Trade-Offs Investment Incentives Network Innovation Costs of Regulation vs. Application Innovation User Control Internet’s Ability to Realize its Economic, Social, Cultural and Political Potential 31

  32. Conclusion • Framework • Potential impact on IETF standards • Regulation vs. competition plus disclosure • Non-discrimination and user choice 32
