<p class="MsoNormal"><span style="color:#0070C0">I’m not entirely sure what this does, but playing with it suggests that this means I am only sampling packets that are egressing an interfacing, i.e., ignoring packets ingressing an interface. I turned this
on because I assume it means I am not doublesampling a flow, meaning sampling the flow once when it enters the switch and then again when it exits. But I am not sure.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#0070C0">So it appears that iPerf3 likes to transfer test traffic in 1,500 byte frames. And I can’t help but notice that:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#0070C0"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-size:9.0pt;font-family:"Courier New"">1536000 / 1500 = 1024<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#0070C0"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#0070C0">And of course, I’m sampling with a rate of N = 1024.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#0070C0"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#0070C0"> So its not really a bug, but I’m wondering if this is what is going on:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#0070C0"><o:p> </o:p></span></p>
<ol style="margin-top:0in" start="1" type="A">
<li class="MsoListParagraph" style="color:#0070C0;margin-left:.25in;mso-list:l2 level1 lfo3">
A flow of packets enter the OVS switch<o:p></o:p></li><li class="MsoListParagraph" style="color:#0070C0;margin-left:.25in;mso-list:l2 level1 lfo3">
The first 1024 packets of my test traffic are identified as part of one flow; one of those packets is randomly sampled for IPFIX<o:p></o:p></li><li class="MsoListParagraph" style="color:#0070C0;margin-left:.25in;mso-list:l2 level1 lfo3">
The IPFIX process within the OVS Switch notes the packet payload – 1,500 bytes – and records that for IPFIX’s “octetDeltaCount” statistic, which is defined to be the number of octets within flow.<o:p></o:p></li><li class="MsoListParagraph" style="color:#0070C0;margin-left:.25in;mso-list:l2 level1 lfo3">
However, because I am sampling at N = 1024, OVS then does a quick multiplication ( 1500 bytes X 1024 = 1536000 octets ) and records that number as “octetDeltaCount”<o:p></o:p></li><li class="MsoListParagraph" style="color:#0070C0;margin-left:.25in;mso-list:l2 level1 lfo3">
After sampling the one packet, OVS exports the data record, i.e. does not aggregate the statistics over a 60 second timeframe.<o:p></o:p></li></ol>
<p class="MsoNormal"><span style="color:#0070C0"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#0070C0">Step D is what concerns me. If OVS is automatically compensating for the N Sampling, that’s fine, but I need to understand that behavior. A lot of IPFIX collectors will learn about the N Sampling and will do
additional calculations on the reports; this of course distorts the final data.<o:p></o:p></span></p>
