Prime examples of what this article talks about is DoS and DDoS, and perhaps now to a lesser extent Smurfs. It seems now that most security corporations are now focusing on preventing attacks by increasing network security in perhaps a futile effort to eliminate or reduce the possible number of zombies/bots, but still this is a far cry from a full solution as there will allways be vunerable systems, and the ability to saturate lines or exhausting server memory.
Could a possible solution be to limit the frequency of packets under a certain size being sent on OS cleints, similar to flood control on web boards, these days with the size of most peoples lines small packets like that are rarely sent anyway, and most programs use far bigger or more complex packets ussaully. A real solution to DoS attacks is worth millions though.
