Turning these routers "red" gives a false impression on performance to end destinations.

»Tools FAQ »Why am I seeing so much packet loss in my provider's network?
Some providers are rate-limiting how often they respond with the TTL-exceeded ICMP packets used by traceroute and similar tools like the Packet Loss Test. This is done to prevent attacks against these routers, since responding to these packets requires much more CPU time than simply forwarding the packet does. If the router is set up to rate-limit, it will respond to a certain number of traceroute packets per second, and once that many have been received, it will stop responding to them for that second -- which will appear as packet loss. You are not losing any "real" traffic, assuming the final hop of your traceroute isn't showing any loss.]]> http://www.dslreports.com/forum/remark,20301069 Tue, 08 Apr 2008 07:55:01 EDT
