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 can be found here: https://learn.nsrc.org/perfsonar

 

perfSONAR Node Reference Implementation

November 1, 2023

ESnet has assembled a reference implementation of a host that can be deployed as a DTN or as a high-speed GridFTP test machine. The host can fill a 100Gbps network connection with disk-to-disk data transfers using GridFTP. Below is a description of the hardware we used, as well as the most important tuning settings. Other similar hardware should give similar performance.  Read More
