Does any know where the link is for

Mailman List Mirror (Read Only)

I seem to recall someone doing a paper on
ICMP and traceroute -at times-, as not always being indicative of
actual network performance...

  Does anyone remember who, or where,
that link is ?

Thanks in Advance.

   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&gt;

  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&gt;

  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 !
