Hi Jon, Been trying to respond to this for what now seems like, and probably is, months. I agree that the GENI proposal is not very imaginative. But, whatever you want to do; whoever you want to set up paths to: the first hurdle is the PoP bill, so that seems to be covered in their proposal. We would need to do the same - UK-Light or not, there is still a bill to pay. Then you can do something real. Seems we've been there before? > plus the UK already has UK light, and if we talk nicely to ireland, > they just got some licensed spectrum for research - if we talk nicely > to Ofcomm, we might get some too... It's no problem getting a spectrum license: all you need is money. The funding available will define the limits of what can be done, say if the license is priced by km-squared of coverage proportional to the total area of the issuing authority. Once you've got it you have to show you are using it else the authority may withdraw the license. On some details, I am generally on the same hymn sheet subject to continuing discussions, but: > 2/ a network that is entirely crashproof by proof and DoS resistent by > design with liability models included as part of interdomain/sla > (i.e. a competetive multi-provider model still allowed) We need theory to do this. Virtualiazable components are within our reach, maybe based on designs GENI might do. However, I think their expectations on optical interconnect are well off. BTW: www.chiaro.com went off the air - anyone know why? Regards, Alistair -- Prof. Alistair Munro, Toshiba Professor of Communications Networks Dept.
