  1. The Future Internet as a Model for Future Public Systems Jon Crowcroft, Jon.crowcroft@cl.cam.ac.uk http://www.cl.cam.ac.uk/~jac22

  2. Future Internet Research • Network research • Resilience, scale, flexibility • Content distribution • Internet of things • All optical core, all wireless access • Etc etc etc • Yada yada yada • Blah blah blah…

  3. Future Internet Research • Use as model for other publc services • Past Internet delivered • Decentralisation • Federation • Adaptation • Evolution • How?

  4. Past Internet • Decentralised, Hierarchical Routing • Route around trouble • Pool resources • Distributed Resource Management • Congestion control in end • Pool resources • Federation • Policy route admits many business models • Pool resources • Layered Abstraction • Can evolve independently • Hence Web, VOIP, IPTV, OSNs, etc

  5. Past Internet uses • Advertisement/discovery • Add a host, router net is trivial • Rendezvous • No pre-arrangement necessary • Hierarchy • Scale arbitrarily • Names, addresses, routes, capacity etc

  6. Architecture Design Rules • End-to-end model • Postel Principle • Amdahl/Cray/Moore’s laws etc • Consumer electronics scale

  7. Three examples of applying model • Transportation • Use end2end model • Energy • Use federation model • Government • Use extreme decentralization model

  8. Transportation • The use of end2end principle:- • Separate routing and “transport” • Person as packet, switched to destination • Adapt routes in situ, en route • Congestion control => congestion exposure • London was a good start :-)

  9. Energy • Many many many providers • Federate • Build subtle meta-business rule system • == BGP • Adapt (a la routing and traffic engineering) • Use higher level information • about demand • Co-optimise Energy with other things • E.g. 1. Transport & 2. Interweb • We have £6M EPSRC project looking at 2.

  10. Government • Decentralize = subsidiarity • IP name/address/content governance • Hierarchy • Hides complexity • May be inflexible to multi-dimensional • Social, economic, safety etc • So my weakest example • Typical geek trying to understand politics • getting reductionist

  11. Conclusions • The lessons of the Internet are deep • We can apply them in other domains • Interesting synergies may emerge • Might be a good FISB UK topic • UK scale is excellent for ideas • Much better than top down • Database state unnecessary • Avoid embarrassing errors like NPfIT
