We have more trouble with services from another carrier that are terminated using an MRV brand CPE device that has exceedingly small buffers for any kind of bursts and seems to choke when you go over the burst parameter so that instead of getting policed to the correct speed, you get about 10% of the speed until it recovers a few seconds later.</div><div id="yui_3_16_0_1_1444719735105_19065" dir="ltr"><br></div><div id="yui_3_16_0_1_1444719735105_19065" dir="ltr"><br></div><div id="yui_3_16_0_1_1444719735105_19065" dir="ltr">regards,</div><div id="yui_3_16_0_1_1444719735105_19065" dir="ltr">Tony</div><div id="yui_3_16_0_1_1444719735105_19065"><br></div><br> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;" id="yui_3_16_0_1_1444719735105_18886"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, Sans-Serif; font-size: 16px;" id="yui_3_16_0_1_1444719735105_18885"> <div dir="ltr" id="yui_3_16_0_1_1444719735105_19063"> <hr size="1" id="yui_3_16_0_1_1444719735105_19345"> <font size="2" face="Arial" id="yui_3_16_0_1_1444719735105_19064"> <b><span style="font-weight:bold;">From:</span></b> "paul+ausnog@oxygennetworks.com.au" <paul+ausnog@oxygennetworks.com.au><br> <b><span style="font-weight: bold;">To:</span></b> 'Tim Jones' <tim@iseek.com.au>; ausnog@lists.ausnog.net <br> <b><span style="font-weight: bold;">Sent:</span></b> Wednesday, 14 October 2015, 8:38<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [AusNOG] NBN Q<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_1_1444719735105_18884"><br><div id="yiv7095309391"><style>#yiv7095309391 #yiv7095309391 --

I did a bit of a Google on the topic but am probably using the wrong terminology to find anything useful. Does anyone have any more information they could share on this?</span></div></div></div></div></div></div> </div> </div> </div></body></html>
