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
