perfSONAR is a network measurement toolkit designed to provide federated coverage of paths, and help to establish end-to-end usage expectations. There are 1000s of perfSONAR instances deployed world wide, many of which are available for open testing of key measures of network performance. This global infrastructure helps to identify and isolate problems as they happen, making the role of supporting network users easier for engineering teams, and increasing productivity when utilizing network resources. perfSONAR has been developed through an international collaboration led by Internet2, ESnet, Indiana University, and GEANT.
perfSONAR provides a uniform interface that allows for the scheduling of measurements, storage of data in uniform formats, and scalable methods to retrieve data and generate visualizations. This extensible system can be modified to support new metrics, and there are endless possibilities for data presentation.
The perfSONAR project collaborated on a podcast with RCE (Research Computing and Engineering), a group that explores topics relevant to the High Performance Computing and Research Computing communities. This podcast offers an introduction to perfSONAR, as well as discussion about what the future holds. It is ~45 minutes in length, and can be found here:
