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 Internet2, ESnet, RNP, and GEANT.
ESnet has deployed perfSONAR services at over 45 locations, and recommends that all sites deploy at least one perfSONAR host as well. See the fasterdata perfSONAR HOWTO for more information.
