My research group, as well as everyone who currently uses PlanetLab (and presumably the future GENI platform, if it comes to pass) faces a different deployment scenario than what the operational folks are used to. Setting up anycast might be possible, but is operationally very very difficult for

what do you think of as expensive? Anything that has 1000% or higher markup. There is also another kind of expense: solving the SiteFinder problem took a lot of time, public outcry and moral outrage from a large group of people. It would have been nice to just scoot over to a competitor. These

Stephane, It is not artificial, it is the way it has to work. You cannot have multiple registries for one TLD, period. No more than you can have perpetual motion. Be careful about making statements about impossibility without an associated impossibility proof. History is full of people who

But I'll do this only if asked. Consider it done. Ok, here is a rough protocol sketch. For simplicity, I'll gloss over non-critical details, e.g. timeout handling. Bear with the notation, we'll end up with something neat at the end: - assume that R1 and R2 pick random numbers r1 and r2

Hi Ed, The one weakness I see in the presentation of CoDoNS is one that is common amongst academic exercises. While it treats a technical problem in a formally defined say, it suffers from the assume frictional surfaces syndrome. This disease is not fatal, it is more like the flu,

Stephane Phillip, I'm thinking of writing a short report that summarizes the invaluable discussion here and beefing up the system sketch. I think we now agree that it is possible to have multiple operators manage names in a single, shared namespace without recourse to a centralized

Hi, Let me expand on how DNSSEC coupled with a cooperative, p2p architecture for DNS can help enable competition among TLDs. The short summary is: - CoDoNS+DNSSEC enable any server to securely serve any name, which makes it possible, should the community decide to pursue it,
