Hi Guys, Is anyone using a MikroTik router as an NBN head end unit? And if so have you managed to create a traffic queue scenario which satisfies the NBN 10ms peak burst rate specification http://www.nbnco.com.au/content/dam/nbnco2/documents/sfaa-wba2-product-catal... We need to be able to configure the Peak Burst Size (PBS) down to less than 10ms. Anything in excess of that is dropped by NBN traffic policing. The limitation of the MikroTik OS (and maybe hardware) is that we can only configure PBS down to 1 second (25M/second) The result is that NBN traffic policing drops packets that exceed 0.25M/10ms, significantly impacting TCP throughput and exhibiting the anticipated sawtooth throughput profile as TCP constantly ramps up and drops back due to lost packets. To make it work I think we need to be able to set a peak burst rate such that a 25M NBN service can have a peak burst rate of 0.25M per 10ms or even better would be .125M/5ms (as 10ms is the Max spec of the NBN) If anyone has this working successfully, I would love to hear how you achieved it :) Kind regards Murray Southwell Tasmanet Pty Ltd Manager - Network Services murray@tasmanet.com.au 0361652511 0418145979
