  1. Reducing Internet Latency: a survey of techniques and their merits Bob Briscoe, Anna Brunstrom, Andreas Petlund, David Hayes, David Ros, Ing-JyhTsang, Stein Gjessing, Gorry Fairhurst, CarstenGriwodz, Michael Welzl

  2. summary • industry roadmap of techniques • gain vs pain • latency reduction against deployability • “A Survey of Latency Reducing Techniques and their Merits” • 322 references • available via http://riteproject.eu/publications/ • evolved from BT roadmap work, but repurposed • a company tries to prioritise the quick wins • an industry also needs to identify hard problems being avoided

  3. roadmap around body of survey I

  4. roadmap around body of survey II
