Monitoring
This research focusses on improving and extending perfSONAR, the infrastructure for network performance monitoring. The purpose is to make it easier to solve end-to-end performance problems on paths crossing several networks. perfSONAR delivers a set of services that offer performance measurements in a federated environment.
