Re: Effects of traffic shaping ICMP (&c.)

Could traffic shaping, or similar QoS configurations, be used to solve such issues in a more general way? For example, if my source of packet flooding is ICMP, then I'd like to be able to dedicate as much as 1/10th (e.g.) of the bandwidth of each link to ICMP. That's plenty of ICMP, but it's not so much that an attack using ICMP would be effective.

At the last NANOG, there was a presentation about Cisco's CAR and how @Home was using it to limit ICMP and detect unusual ICMP activity. Well, that was part of the talk, at least. http://www.nanog.org/mtg-9811/ppt/witt/index.htm : presentation slides http://www.nanog.org/mtg-9811/cartalk.ram : presentation in RealVideo Pete.
