<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">PerfSonar does provide an interface to run various network performance tests. You can use it to run scheduled or one-off tests. It’s used widely on R&E networks
around the world, with much development work coming out of ESNet and Internet2 (the USA equivalents of AARNet). <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The BWCTL test is iperf-based and used for throughput measurements. Another, OWAMP, tests packet loss & latency – which is often sufficient to identify network
problem, without filling your pipes with production-impacting iperf/BWCTL traffic.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I wouldn’t say that perfSonar is a simple way of throwing up a front-end to iperf however… it takes a certain amount of effort to get it up and working. However
tied in with a dashboard such as MadDash, it can provide an informative view of network-wide performance.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:5.25pt">There was a Packet Pushers episode a while back about PerfSonar - they seemed to indicate that it included a more interesting frontend than the default iperf stuff.<br>

My memory is a bit hazy on it though - original podcast here: <a href="http://packetpushers.net/show-163-open-source-perfsonar-finds-the-flaws-impacting-the-flows/">
