perfSonar Logo

perfSONAR is a tool for end-to-end monitoring and troubleshooting of multi-domain network performance. perfSONAR provides network engineers with the ability to test and measure network performance, as well as to archive data in order to pinpoint and solve service problems that may span multiple networks and international boundaries. perfSONAR is currently deployed in over 1,700 locations around the world, and is extremely valuable when doing network troubleshooting. perfSONAR has been developed through an international collaboration led by ESnet, GÉANT, Indiana University, and Internet2. You can visit the perfSONAR website by clicking here.

To learn more about the capabilities of perfSONAR and its features, watch our perfSONAR training video series. Get started with "What is perfSONAR?"
