“The original Science DMZ model provided a way of securing high-throughput data transfer applications without the use of enterprise firewalls,” says Dart. “You can protect data transfers using technical controls that don’t impose performance limitations.”
Through a consortium of Science DMZs and links to NERSC via CENIC’s CalREN and the DOE’s ESnet, the connection enables UCSC to carry out the high-speed transfer of large data sets produced at NERSC, which supports the Dark Energy Spectroscopic Instrument (DESI) and AGORA galaxy simulations, at speeds up to five times previous rates. These speeds have the potential to be increased by 20 times the previous rates in 2018. Peter Nugent, an astronomer and cosmologist from the Computational Research Division, was pivotal in the effort. Read UC Santa Cruz’s press release.
ESnet, Network Startup Resource Center Combine Expertise to Spread the Word
For members of the established research and education (R&E) networking community, attending conferences or sitting in on workshop sessions is the normal way to learn about the latest equipment, architecture, tools and technologies.
But for network engineers striving to establish basic R&E infrastructure where bandwidth and other resources are scarce, the University of Oregon’s Network Startup Resource Center (NSRC) is often the primary information conduit. NSRC staff travel to emerging nations in Africa, Asia-Pacific, Middle East and South America where they hold intensive hands-on training courses combined with direct engineering assistance to bring institutions up to speed.
And for the second time in a year, ESnet and the NSRC have produced and released a library of short explanatory videos to help network engineers around the world gain basic knowledge, set up basic systems and drill down into areas of specific interest. In December, 15 videos detailing the Science DMZ network architecture were posted, covering the background and structure, specific designs, and techniques and technology.
“The goal is to make the information more accessible to networking staff, in the U.S. and particularly in emerging economic areas where institutions are trying to bootstrap a research network,” said ESnet Network Engineer Eli Dart, who developed the Science DMZ concept with Brent Draney of the National Energy Research Scientific Computing Center (NERSC). Both ESnet and NERSC are DOE Office of Science User Facilities managed by Lawrence Berkeley National Laboratory.
Created in 1986, the U.S. Department of Energy’s (DOE’s) Energy Sciences Network (ESnet) is a high-performance network built to support unclassified science research. ESnet connects more than 40 DOE research sites—including the entire National Laboratory system, supercomputing facilities and major scientific instruments—as well as hundreds of other science networks around the world and the Internet.
Step 9: Why just rent fiber? Pick up your own dark fiber network at a bargain price for future expansion. In the meantime, boost your bandwidth to 100G for everyone. (2012)
Step 10: Here’s a cool idea, come up with a new network design so that scientists moving REALLY BIG DATASETS can safely avoid institutional firewalls, call it the Science DMZ, and get research moving faster at universities around the country. (2012)
Step 12: 100G is fast, but it’s time to get ready for 400G. To pave the way, ESnet installs a production 400G network between facilities in Berkeley and Oakland, Calif., and even provides a 400G testbed so network engineers can get up to speed on the technology. (2015)
Step 13: Celebrate 30 years as a research and education network leader, but keep looking forward to the next level. (2016)
BioTeam and ESnet are partnering to offer a webinar on the Science DMZ architectural paradigm. While streamlining a network design to facilitate “friction free” research paths, the Science DMZ has been widely adopted by the research and education (R&E) community and is being implemented at many locations around the world. Using this approach, the task of data mobility becomes less of a mystery, and more of a routine part of scientific networks.
This event will occur on Monday, May 18th, between 2pm and 4pm EDT and is open to the general public. We would like to encourage network operators and researchers (including, but not limited to, life science researchers) to attend this no-cost event. For complete information on registration and logistical details, visit: http://bioteam.net/2015/04/science-dmz-101/. Registration will close when the number of registration slots has been exhausted.

Berkeley Lab staff from five divisions will share their expertise in a panel discussion on “Creating Super-facilities: a Coupled Facility Model for Data-Intensive Science”at the Internet2 Global Summit to be held April 26-30 in Washington, D.C. The panel was organized by Lauren Rotman of ESnet and includes Alexander Hexemer of the Advanced Light Source (ALS), Craig Tull of CRD, David Skinner of NERSC and Rune Stromsness of the IT Division.
The session will highlight the concept of a coupled science facility or “super-facility,” a new model that links together experimental facilities like the ALS with computing facilities like NERSC via a Science DMZ architecture and advanced workflow and analysis software, such as SPOT Suite developed by Tull’s group. The session will share best practices, lessons learned and future plans to expand this effort.
Also at the conference, ESnet’s Brian Tierney will speak in a session oh “perfSONAR: Meeting the Community’s Needs.” Co-developed by ESnet, perfSONAR is a tool for end-to-end monitoring and troubleshooting of multi-domain network performance. The session will give an overview of the perfSONAR project, including an overview of the 3.4 release, a preview of the 3.5 release, an overview of the product plan, and an overview of perfSONAR training plan.
A joint effort between ESnet, Internet2, Indiana University, and GEANT, the pan-European research network, perfSONAR is a tool for end-to-end monitoring and troubleshooting of multi-domain network performance. In January 2014, perfSONAR reached a milestone with 1,000 instances of the diagnostic software installed on networking hosts around the U.S. and in 13 other countries. 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 service problems that may span multiple networks and international boundaries.
At the workshop, Tierney will give an introduction to perfSONAR and present a session on debugging using the software. Zurawski will talk about maintaining a perfSONAR node, describe some user case studies and success stories, discuss “Pulling it All Together – perfSONAR as a Regional Asset” and conclude with “perfSONAR at 10 Years: Cleaning Networks & Disrupting Operation.”
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.

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.
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.
