This may sound a bit ridiculous, but say the timer is every 0.25ms. 100kbit per 0.25ms = 400,000kbit or 400 mbit. It is remotely possible to hit a 300 mbit limit with only 100kbits of traffic, if the timer is sufficiently short, and your traffic is sufficiently bursty. Unless your traffic is Mcast, I doubt that issue is related. Can you ask your provider how exactly they are limiting the pipe? When dealing with 300 or so megs, I doubt they will be shaping with a policy friendly to you, as the logistics of doing so are a bit difficult. --Phil -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Alex Rubenstein Sent: Monday, July 15, 2002 11:06 PM To: Phil Rosenthal Cc: nanog@merit.edu Subject: RE: fractional gigabit ethernet links?

Hello Alex,
I'd say this sounds obvious, but may be deceptively so... If you are taking a pipe capable of 1000 mbit, and rate-limiting it to
311 mbit, the logic used may be:
In the last 1000 msec have there been more than 311mbits? If yes: drop.
Except, we're at the levels of 100 kbit/second in our tests. I did just find CSCdr94172, which might be related. -- Alex Rubenstein, AR97, K2AHR, alex@nac.net, latency, Al Reuben -- -- Net Access Corporation, 800-NET-ME-36, http://www.nac.net --
