​Real-time, multi-domain performance monitoring​.

perfSONAR can be used by GÉANT, national research and education networking (NREN) organisations, campuses and major projects for quick and easy performance troubleshooting.


It provides easy, transparent end-to-end monitoring, giving access to network measurement data from multiple network domains. It can operate at local level or around the globe and is scalable to provide at-a-glance information about multiple network paths simultaneously.


By tracking performance across and between domains it is now possible to identify and rectify any potential performance bottlenecks, helping research teams focus their efforts on their research and allowing NRENs to identify where investments in new capacity will provide the best return. With more than 1,400 measurement points​ across the globe, it is now far easier for NRENs and research teams to accurately measure network performance and ensure it meets their research needs.​

The development of perfSONAR is the result of the combined work of GÉANT, Internet2, ESnet and Indiana University.


What the Users Say

PerfSONAR helps distributed project teams monitor their network performance quickly and easily to ensure projects can focus on their research and have confidence in the networks they are using. Find out how neuGRID use perfSONAR to support their international project.


​What the NRENs say

red_iris.gif​"The network monitoring in a multidomain environment is becoming increasingly necessary due to the high demand of point to point circuits dedicated to specific projects that involve many partners from different locations. The perfSONAR platform allows a simple way to do it once it is deployed in all domains involved. This, in fact, enables a rapid response to the resolution of problems that previously could involve long response times."

Alberto Escolano Sanchez, Network Engineer, RedIRIS

​​"perfSONAR will provide us effective and comprehensive access to the monitoring data throughout the GÉANT and NREN domains, and will give us the ability to run on-demand tests across multiple domains without having to make lots of phone calls. Saving precious time will helps us to detect potential problems, bottlenecks or performance issues even before our users experience their effect, maintaining the quality of the service we give them."

Toby Rodwell, NOC Manager, GÉANT

RENATERv2.jpg​"When dealing with difficult end-to-end communication issues, across multiple domains, the new GN3 perfSONAR service enables the network operator to monitor network performance and highlight any issues. This would allow the NOC an PERT engineers to quickly identify the cause and location of the problem and eliminate the issue with minimal network down time.”

Frederic Loui, Network Manager, RENATER​
