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 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.

ESnet’s Inder Monga Co-authors Article on Growing Role of Optical Networks


ESnet Chief Technologist Inder Monga is co-author of “Optical Networks Come of Age,” was has just been published in the September 2014 issue of Optics and Photonics News.

Although fiber optic transmission capacity has grown by seven orders of magnitude in just 20 years, these systems serve mainly as the “fat pipes,” the large-scale plumbing of the Internet, according to the article. But that is changing.

“Greater use of optical networks—particularly in network edge applications that carry less aggregated, more “bursty,” service traffic—and continued traffic growth will soon revise this picture,” the authors write. “A changing landscape in fiber optic communication technologies is stimulating a resurgence of interest in optical switching. These trends are coming together in ways that hold promise for the long-anticipated widespread deployment of optically switched fiber networks that respond in real time to changing traffic and operator requirements.

“The ultimate mission is to enable the next-generation Internet—one that can support terabit-per-second speeds, but that remains economical and energy efficient,” the authors write.

In addition to Monga, the authors are Daniel Kilper, University of Arizona; Keren Bergman, Columbia University; Vincent W.S. Chan, MIT; George Porter, University of California, San Diego; and Kristin Rauschenbach, Notchway Solutions LLC.

Registration Now Open for 2014 Technology Exchange Conference


Registration is now open for the 2014 Technology Exchange, a leading technical event in the global research and education networking community. The annual meeting is co-organized by ESnet, the Department of Energy’s Energy Sciences Network, and Internet2. The conference will be held Oct. 27-30 in Indianapolis.

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.

According to the conference website, the technical challenges facing organizations today are not confined to the network alone and require the convergence of networking, computing, storage and other, emerging technologies. The Technology Exchange brings together the community’s technology visionaries, including the most inventive chief technologists, scientists, engineers, architects, operators and students in the world, to address these demands.

ESnet Student Assistant Henrique Rodrigues Wins Best Student Paper Award at Hot Interconnects


Henrique Rodrigues, a Ph.D. student in computer science at the University of California, San Diego, who is working with ESnet, won the best student paper award at the Hot Interconnects conference held Aug. 26-28 in Mountain View, Calif. Known formally as the 2014 IEEE 22nd Annual Symposium on High-Performance Interconnects, Hot Interconnects is the premier international forum for researchers and developers of state-of-the-art hardware and software architectures and implementations for interconnection networks of all scales.

Rodrigues’ paper, “Traffic Optimization in Multi-Layered WANs using SDN,” was co-authored by Inder Monga, Chin Guok and Eric Poulyou of ESnet, Abhinava Sadasivarao and Sharfuddin Syed of Infinera Corp. and Tajana Rosing of UC San Diego.

“Special thanks to ESnet that gave me the opportunity to work on such an important and interesting topic,” Rodrigues wrote to his ESnet colleagues. “Also to the reviewers of my endless drafts, making themselves available to provide feedback at all times. I hope to continue with the good collaboration moving forward!”

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.
