I've got users who tend to panic if their latency hits250msbetween here and the moon (slight exaggeration, but only slight). I just love it when I've got people blaming me because the 20th hopona traceroute starts returning * * * instead of times.that's icmp ttl expired messages.I know that, and I try to explain it to my customers... but it doesn't answer the first part of the question - what will throttling ICMP do to ping and traceroute times? My gut reaction is that it will a. slow them down and/or b. discard a lot of them making the circuit look unreliable to ping. But I don't know enough about the underlying technology to be sure of that.
As they say, if you dont set the rate limit too low then you wont encounter drops under normal operation. Steve
