Try this again: The routing works by everyone assuming if a node handles key X well and key Y is "close" to key X, then it will handle key Y well. If nobody can agree how "close" X is to Y, because they've all reordered the hashspace, they won't agree on where to send keys and specialization will be impossible. Specialization of a node means, that it has become "better" in some area of hashspace than in others and that the nodes neighbors know about know this. If every node has it's own reordered hashspace, they can't know about these same areas. Yes, if you break the routing you can prevent targetted DoS. Really Stupid Routing (RSR) is immune to it. __________________________________________________________________ Gesendet von Yahoo!
