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
