I haven't found the original, it was dated about 97-99... NLANR, perhaps ???? But, there are more recent write ups... Here are two I encountered: <http://www.inetdaemon.com/tools/ping_is_not.html> This one explains why PING -may- be bad, but regular performance, OK... (Call it the end user explanation of ACL-CAR intervention) :) And this one,( more what I was looking for..) a detailed explanation of the caveats of clever tracerouting providing Bogus Data. <http://homepage.ntlworld.com/robin.d.h.walker/cmtips/traceroute.html> I needed something for a rookie tech who was "whining" about a site tracerouting with an intervening router - appearing - slow (An exchange BGP router, go figure), but an end to end of -38 ms-, -consistent- and with -no- loss. He didn't believe the explanation of the BGP rumble... and I was growing frustrated with the need for detail, when it just wasn't registering ! :( "When the Judge is a blind man, it can be -exasperating- trying defend your choice of the Winner of the Art fair." :P
