Note: This page is under construction and can change quite often, information provided is still preliminary and subject to change.



NOTICE (June 26, 2014): There was a recently announced vulnerability (See EGI SVG EGI-SVG-2014-7162 for details or refer to FAQ at http://psps.perfsonar.net/toolkit/FAQs.html#Q77) in the Cacti component of the perfSONAR Toolkit deployments in use in WLCG and OSG. A fix was provided by the perfSONAR-PS developers in the form up updated RPMS and ISO images. All sites should update their installations.

Details at https://twiki.cern.ch/twiki/bin/view/LCG/CactiperfSONAR



Mandate

  • Ensure all relevant network and transfer metrics are identified, collected and published
  • Ensure sites and experiments can better understand and fix networking issues
  • Enable use of network-aware tools to improve transfer efficiency and optimize experiment workflows

Objectives

  • Identify and continuously make available relevant transfer and network metrics
  • Document metrics and their use
  • Facilitate their integration in the middleware and/or experiment tool chain
  • Coordinate commissioning and maintenance of WLCG network monitoring
    • Finalize perfSONAR deployment
    • Ensure all links continue to be monitored and sites stay correctly configured
    • Verify coverage and optimize test parameters

Members

Shawn McKee (chairperson), Marian Babik (co-chair), clouds, experiment contacts and product owners to be invited (proposed to invite previous members of perfSONAR TF, i.e. https://twiki.cern.ch/twiki/bin/view/LCG/MeshUpdates as well as members knowledgeable about FAX, AAA, FTS, PhEDEx, Panda or Rucio)

A very important component of the working group is the cloud/mesh leaders for the perfSONAR-PS infrastructure. Each regional or VO specific "mesh" should have a leader. Details on the leaders and their responsibilities is document at perfSONAR Mesh Leaders.
