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: [email protected] [mailto:[email protected]] On Behalf Of Alex Rubenstein Sent: Monday, July 15, 2002 11:06 PM To: Phil Rosenthal Cc: [email protected] Subject: RE: fractional gigabit ethernet links?

I did just find CSCdr94172, which might be related. -- Alex Rubenstein, AR97, K2AHR, [email protected], latency, Al Reuben -- -- Net Access Corporation, 800-NET-ME-36, http://www.nac.net --
