NRL and Collaborators Conduct 100 Gigabit/Second Remote I/O Demonstration


The Naval Research Laboratory (NRL), in collaboration with the DOE’s Energy Sciences Network (ESnet), the International Center for Advanced Internet Research (iCAIR) at Northwestern University, the Center for Data Intensive Science (CDIS) at the University of Chicago, the Open Cloud Consortium (OCC) and significant industry support, have conducted a 100 gigabits per second (100G) remote I/O demonstration at the SC14 supercomputing conference in New Orleans, LA.

The remote I/O demonstration illustrates a pipelined distributed processing framework and software defined networking (SDN) between distant operating locations. The demonstration shows the capability to dynamically deploy a production quality 4K Ultra-High Definition Television (UHDTV) video workflow across a nationally distributed set of storage and computing resources that is relevant to emerging Department of Defense data processing challenges.

ESnet partners with Corsa, REANNZ and Google in first end-to-end trans-Pacific SDN BGP multi-AS network


Corsa Technology, ESnet, and REANNZ have successfully demonstrated the first international SDN-only IP transit network of three Autonomous Systems (AS) managed as SDN domains.  The partners took the approach of building and testing an Internet-scale SDN solution that not only embodies the SDN vision of separation of control and data, but enables seamless integration of SDN networks with the Internet.

This first implementation passed through 3 AS domains, namely Energy Sciences Network (ESnet) at Berkeley, REANNZ at Wellington, and Google research deployment at Victoria University, Wellington (NZ).  ESnet’s node used the Corsa DP6420 640Gbps data plane as the OpenFlow hardware packet forwarder, controlled by the open-source VANDERVECKEN SDN controller stack (based on RouteFlow and Quagga).

4th International Workshop on Network-aware Data Management at SC14


NDM’14, the 4th International Workshop on Network-aware Data Management, will be held Sunday, Nov. 16, in conjunction with the SC14 conference in New Orleans. The workshop will be held from 1:30-5:30 p.m. in room 274 of the Ernest N. Morial Convention Center.

The workshop, co-organized by ESnet’s Brian Tierney and Surendra Byna of Lawrence Berkeley National Laboratory and Mehmet Balman of VMware, Inc. and affiliated with Berkeley Lab, will feature keynote talks and technical presentations. Read more at: http://ndm-meeting.org

SC14 attendees can participate in the workshop either by adding Workshops to their Technical Program registration or buying a Workshops-only badge. See http://sc14.supercomputing.org/register for details.

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.

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.
