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…
Future Internet Research
Use as model for other publc services
Past Internet delivered Decentralisation Federation Adaptation Evolution
How?
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
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
Architecture Design Rules
End-to-end model Postel Principle Amdahl/Cray/Moore’s laws etc Consumer electronics scale
Three examples of applying model
Transportation Use end2end model
Energy Use federation model
Government Use extreme decentralization model
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 :-)
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.
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
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
