  1. PerfSONAR deployment Campana, McKee

  2. From Oslo … • Shawn’s presentation in Oslo summarizes perfectly the current situation and the forthcoming challenges • https://indico.cern.ch/getFile.py/access?contribId=3&resId=1&materialId=slides&confId=196896 • Increasing number of sites demands to reconsider the deployment, operations and monitoring model • How to configure perfSONAR boxes in a large NxN channel matrix (today static)? • How to operate in a way that all channels are tested but not congested? • How to visualize a O(100)xO(100) number of links? Simone Campana - ATLAS SW&C Week

  3. How to start: some ideas • Focus on the sites (and links) of primary importance for experiments • list to be built • Get perfSONAR properly handled at the WLCG level • Publication in GOC, downtimes etc .. • Get perfSONAR installed and configured at least for testing cloud/region/country links • Instructions from various experiments need some consolidation Simone Campana - ATLAS SW&C Week

  4. With some new development • Very promising development from Internet2 on mesh configuration: test and deploy on candidate region • US is the obvious candidate, then extend • Define with the experiments rates and frequency of tests for various classes of links • Testing the full mesh at the current rate would congest many links • Extend perfSONAR dashboard so that it can cope with the full mash • Sorting, filtering, … Simone Campana - ATLAS SW&C Week

  5. Conclusions • This is not going to be a short time effort. • Some development is also needed • Main experts from various experiments will be contacted soon Simone Campana - ATLAS SW&C Week
