perfSONAR

perfSONAR is an infrastructure for network performance monitoring, making it easier to solve end-to-end performance problems on paths crossing several networks. It contains a set of services delivering performance measurements in a federated environment. perfSONAR has been developed through an international collaboration led by ESnet, Indiana University, Internet2, the University of Michigan, and GEANT.

ESnet has deployed perfSONAR services at over 30 locations, and recommends that all sites deploy at least one perfSONAR host as well. 

The ESnet and the Network Startup Resource Center (NSRC) at the University of Oregon have teamed up to create an extensive video training library to help organizations improve the performance of their networks by deploying the perfSONAR network measurement tools and the Science DMZ network architecture.  The training library (which is now somewhat out of date) can be found here: https://learn.nsrc.org/perfsonar
