At first blush, it sounds like law enforecement will hate it, due to inability to determine the end-points. :-) I need to think about that for a little while... in the meantime, I'll read the paper. ;-) Cheers, - ferg -- Jon Crowcroft wrote: Its that time of year for a new network architecture - rather than build an overlay on IP I reckon the way to build a DOS proof, multipath, resilient network that can function in low or high bandwidth, fixed or mobile, lossy or reliable, connected or disrupted, topologies is to built the packet protocol over an overlay - so my bif is to rebuild IP on Swarms (initial prototype is IPv6 on bittorrent) packet swarming systems are nice because i) you go download your packet, so noone can dos you ii) topological attacks are hard when you dont know where I am getting the different pieces of the packet from. iii) incentive alignment thru the token system enforces approximate symmetry iv) multipath is for free and tunable v) you still have anonimity if you really want it vi) content addressable (pub/sub/ event/notify) is a first class network function vii) multicast is for free of course IP on bittorrent begs the question of what the bittorrent is on....so that's what the NSF proposal would be about (of course i'm not eligable for nsf money:-) so this is a free donation to the US NSF proposal writers guild:) cheers jon remember, you have 2 days left to register for REALMAN in Florence:- http://www.cl.cam.ac.uk/Research/SRG/netos/realman/ p.s. if the GENI is out of the lamp, who is making the 3 wishes...? -- "Fergie", a.k.a.
