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’s Science DMZ Model Speeds Flow of Cancer Data at University of New Mexico

Data from the University of New Mexico’s Cancer Center next-generation genome sequencers is now flying across a 10 Gbps link to the university’s Center for Advanced Research Computing, thanks to the Science DMZ model pioneered by ESnet, according to an article posted by UNM.

According to the article, “This point-to-point connection is a first step toward establishing a campus-wide research network at UNM. The connection is based on the “Science DMZ” model formalized by the Department of Energy’s ESnet in 2010. The new link delivers a low-latency, high-bandwidth, unfiltered connection via UNM’s campus network.”

The article states that the new 10 Gbps link enables fast, reliable, and secure transfer of enormous genome sequence files from the UNM Cancer Center for analysis and subsequent data warehouse archiving. And the model may pave the way for greater research collaborations across the state.

“This project is part of UNM’s larger direction to collaborate across campuses and expand network infrastructure for research here and statewide,” said Chief Information Officer Gil Gonzales. UNM IT works closely with departments and Centers at UNM, and with research institutions throughout New Mexico, to provide production, commodity, and research network services.
