Latest version of perfSONAR network measurement software not just another incremental update


Since it was first released about five years ago, the perfSONAR network measurement toolkit has provided the research and education networking community with tools for end-to-end monitoring and troubleshooting of multi-domain network performance. And over the years, this ability to diagnose network problems has become increasingly important as research is increasingly collaborative and dependent on sharing large data sets.

The latest release of perfSONAR, version 3.4, gives network engineers access to more data about network performance as well as increased security protections. The new version will be discussed in a session called “perfSONAR 3.4: Not Just another Incremental Update” at the Technical Exchange conference being held from Oct. 19-25 in Indianapolis. perfSONAR is developed by a collaboration between the Department of Energy’s ESnet, Internet2, Indiana University and GEANT, the pan-European research network.

perfSONAR provides network engineers with the ability to test and measure network performance, as well as to archive data in order to pinpoint and solve performance problems that may span multiple networks and international boundaries.

ESnet Staff to Share Accomplishments, Expertise at Oct. 27-30 Tech Exchange Conference


Berkeley Lab staff from ESnet, NERSC and the IT Division will be among the presenters at the 2014 Technology Exchange, a leading technical event in the global research and education networking community. The annual meeting is co-organized by ESnet and Internet2. The conference will be held Oct. 27-30 in Indianapolis.

Among the topics to be addressed by Berkeley Lab staff are ESnet’s recently announced 100 gigabits-per-second connections to Europe, the newest release of the perSONAR network measurement software library, Science DMZs and cyber security.

The annual meeting brings together a wide range of technical experts to address the challenges facing the research and education networking community as it supports data-intensive research. The conference will be hosted this year by Indiana University.

ESnet to Boost Big Data Transfers by Extending 100G Connectivity across Atlantic


ESnet, the Department of Energy’s (DOE’s) Energy Sciences Network, is deploying four new high-speed transatlantic links, giving researchers at America’s national laboratories and universities ultra-fast access to scientific data from the Large Hadron Collider (LHC) and other research sites in Europe.

ESnet’s transatlantic extension will deliver a total capacity of 340 gigabits-per-second (Gbps), and serve dozens of scientific collaborations. To maximize the resiliency of the new infrastructure, ESnet equipment in Europe will be interconnected by dedicated 100 Gbps links from the pan-European networking organization GÉANT.

Funded by the DOE’s Office of Science and managed by Lawrence Berkeley National Laboratory, ESnet provides advanced networking capabilities and tools to support U.S. national laboratories, experimental facilities and supercomputing centers.

Among the first to benefit from the network extension will be U.S. high energy physicists conducting research at the Large Hadron Collider (LHC), the world’s most powerful particle collider, located near Geneva, Switzerland. DOE’s Brookhaven National Laboratory and Fermi National Accelerator Laboratory—major U.S. computing centers for the LHC’s ATLAS and CMS experiments, respectively—will make use of the links as soon as they are tested and commissioned.
