Berkeley Lab, Google Host Multi-vendor Interoperability Demo of FAUCET SDN Software

FAUCETIn a real-time demonstration, seven vendors of network equipment came together to successfully test the interoperability of FAUCET, an open-source SDN (software-defined networking) controller. The March 30 event was sponsored by Google, LBLnet (Lawrence Berkeley National Laboratory’s internal network) and ESnet, the U.S. Department of Energy’s high-speed international network managed by Lawrence Berkeley National Laboratory.

The demonstration was organized to sustain momentum for SDN — an emerging technology that decouples the network control plane from the actual data which flows across the network on the data plane. By doing so, SDN introduces the concept of programmability into the network, allowing application owners and network operators to customize network software to meet their needs.

FAUCET, originally developed at REANNZ and the University of Waikato in New Zealand with the support of Google and others, was created to bring the benefits of SDN to a typical enterprise network and has been deployed in various settings.

ESnet Staff Share Award for Program to Increase Role of Women in Networking

ESnet’s Kate Mace, Jason Zurawski and Lauren Rotman, have3 been recognized for their contributions to the WINS program.

Kate Mace, Lauren Rotman and Jason Zurawski of ESnet, along with Wendy Huntoon of KINBER and Marla Meehl of UCAR, are co-recipients of the CENIC 2017 Innovations in Networking Award for Experimental Applications. The award recognizes their work to expand the diversity of the SCinet volunteer staff and provide professional development opportunities to highly qualified women in the field of networking.

Rotman leads ESnet’s Science Engagement Team, of which Mace and Zurawki are members. Huntoon is president and CEO of the Keystone Initiative for Network Based Education and Research (KINBER) and Meehl is network manager for the University Corporation for Atmospheric Research (UCAR) in Colorado.

The five were recognized for their role in developing the WINS Program, or Women in IT Networking at SC, which brings a group of women technology professionals to the SC conference in November for hands-on experience in building and maintaining SCinet, the high capacity network infrastructure that supports the conference.

“This program has exemplified networking in many senses of the word – building a communications infrastructure by creating a strong diverse team and working together,” said ESnet Director Inder Monga. “We’re grateful for the opportunity to work with Marla and Wendy to help make networking at the SC conference more inclusive.”

Seven women attended SC16 under the auspices of WINS, which was launched in 2015 to expand the diversity of the SCinet volunteer staff and provide professional development opportunities to highly qualified women in the field of networking. The 2016 WINS Program is part of a three-year program funded through a National Science Foundation grant and through direct funding from Department of Energy’s ESnet.

“The collaboration you have created, between the University Corporation for Atmospheric Research, the Department of Energy’s Energy Sciences Network, and the Keystone Initiative for Network Based Education and Research, is a powerful one,” CENIC President and CEO Louis Fox wrote to the recipients. “By funding women IT professionals to participate in SCinet and attend the Supercomputing Conference you are helping to foster gender diversity in our field, a critical need.”

The WINS team will receive the award on Tuesday, March 21, 2017, during the annual CENIC conference in La Jolla, Calif. CENIC, the Corporation for Education Network Initiatives in California, operates the California Research & Education Network (CalREN), a high-capacity network designed to meet the needs of over 20 million users, including the vast majority of K-20 students together with educators, researchers, and other vital public-serving institutions in California. ESnet partners with CENIC on the Pacific Research Platform and in a joint cybersecurity initiative.

Diversity & Inclusion POV: Michael Sinatra

At ESnet, we believe that a diverse workforce results in creative ideas and innovations. So we aim to create an inclusive working environment where people feel valued and can share their thoughts and ideas. In this series, we’ll be sharing perspectives from our staff in hopes of sharing our lessons learned and igniting conversations.

 As part of ESnet’s ongoing inclusion effort, we held a workshop, “Empathy: A Building Block for Inclusiveness,” last month to discuss proactive approaches to understanding others. Mukundagiri Kandadai Ramanujam (‘Ram’ for short), Lead Trainer with Love To Share Foundation, facilitated the discussion. Michael Sinatra, a network engineer at ESnet, shares his thoughts on the workshop.

At ESnet, we deal with a lot of complex issues, which generate a lot of subtle risks and benefits. We also have a diverse staff that has different communication styles. I have found Ram’s seminars really helpful in reminding us of the benefit of understanding employees’ underlying concerns when we communicate. 

In the seminar, Ram made the distinction in interpersonal communication among statements that are intellectual or state neutral facts, versus those that evaluate, judge and eventually label. By using empathy to understand the underlying needs being expressed by our coworkers, we can better convey the important things that need to be communicated in our organization without causing emotional issues to block out the underlying needs of the organization. Emotions have a place at work, but they can also cloud our ability to see important issues in our jobs.

The discussion reminded me of an example from a previous workplace. When I was 21 I had a summer job at a factory where, as one of my assignments, I had to do some work with the plant machinist, who had been told by the plant managers that he had an “attitude problem.” In the course of our work, when my colleague began grumbling about something I was doing, I, aware of this person’s alleged attitude problem, tried to be as emotionally neutral as I could to find out—on an intellectual level— why he was grumbling. It turns out that my colleague had identified a serious safety issue in what I was doing. We were able to correct the issue quickly before it caused more problems. I realized that my colleague might not have an attitude problem at all, but he might just have had some trouble communicating important issues to others, and then he would get frustrated when people didn’t take his concerns seriously.

I have tried to apply some of these concepts by being more open about my underlying motivations, especially when expressing concerns about something. At the same time, I have tried to better, and more neutrally, understand my colleagues’ concerns and motivations. Ram showed us that empathy works both ways–by better exposing our own needs and concerns, we can better communicate about the issues that are important to ESnet, and by applying the principles of empathy to our colleagues, we can better understand where they’re coming from, regardless of differences in communication style or culture.

DOE/ESnet, NSF Working to Bridge Lingo Gap between Scientists, IT Security Pros

Note: A recent article in Science Node, a free online publication, developed in collaboration with organizations in the US and Europe, looks at how scientists and IT experts can work together to better understand cyber risks.

As recent events have shown, cyber attacks can come at any time from anywhere and have widespread consequences. While many attacks target personal and financial information, the increasing data-driven nature of research means that scientific research is also dangerously vulnerable in the cyber age.

But when scientists look to cybersecurity experts to shore up these vulnerabilities, they find linguistic barriers. Words like confidentiality, availability, integrity — these terms don’t mean the same to information security professionals as they do to scientists.

To bridge this linguistic divide, funding from National Science Foundation (NSF) and the Department of Energy (DOE) has launched the Open Science Cyber Risk Profile (OSCRP).

Coordinated between the NSF’s Cybersecurity Center of Excellence,  DOE’s Energy Sciences Network (ESnet), and the Center for Trustworthy Scientific Cyberinfrastructure (CTSC), the initiative is building a full risk profile for the open science community.

“Our motivation is to help ensure the trustworthy nature of scientific computing by better understanding the project risks posed to science from cyberattacks,” says OSCRP organizer and CTSC Director Von Welch.

Science DMZ is Focus of Latest Library of Network Training Videos

ESnet, Network Startup Resource Center Combine Expertise to Spread the Word

The Network Startup Resource Center and ESnet have created a Science DMZ video library.

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 Science DMZ video library complements the 29-video perfSONAR library released in July 2016.

“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.

Working Group on Open Science Cybersecurity Risks Releases First Document Draft for Public Comment

Michael Dopheide (left) and Sean Peisert (right).

Over the past several months, ESnet and the NSF Cybersecurity Center of Excellence collaborated with research and education community leaders to develop a risk profile for open science to formally capture and benchmark this expertise, allowing other organizations to apply these best practices more broadly.

Today, the group is releasing its draft Open Science Cyber Risk Profile (OSCRP) and inviting comment from the research community. The OSCRP is designed to help principal investigators and their supporting information technology professionals assess cybersecurity risks related to open science projects. The draft document, along with information on how to comment, can be found at

Managing the security risks to scientific instruments, data and cyberinfrastructure is a priority  for creating a trustworthy environment for science. Assessing, understanding and managing concerns of open science to explicitly capture risks to its integrity and availability, and sometimes also privacy issues, involves making judgments on the likelihood and consequences of risks. Deep experience in understanding cybersecurity and the science being supported is needed to achieve these goals.

The group invites comments on the document prior to final publication in early 2017.  Longer-term, the document is intended to be a living, community document, being updated as open science computing evolves, and also as new approaches to security arise.

Salt Lake City, UT – October 26, 2016 – The University of Corporation for Atmospheric Research (UCAR) and The Keystone Initiative for Network Based Education and Research (KINBER) together with the Department of Energy’s (DOE) Energy Science Network (ESnet) today announce the official launch of the Women in Networking at SC (WINS) program.

Funded through a grant from the National Science Foundation (NSF) and directly from ESnet, the program funds eight early to mid-career women in the research and education (R&E) network community to participate in the 2016 setup, build out and live operation of SCinet, the Supercomputing Conference’s (SC) ultra high performance network. SCinet supports large-scale computing demonstrations at SC,  the premier international conference on high performance computing, networking, data storage and data analysis and is attended by over 10,000 of the leading minds in these fields.

The SC16 WINS program kicked off this week as the selected participants from across the U.S., headed to Salt Lake City, the site of the 2016 conference to begin laying the groundwork for SCinet inside the Salt Palace Convention Center. The WINS participants join over 250 volunteers that make up the SCinet engineering team and will work side by side with the team and their mentors to put the network into full production service when the conference begins on November 12. The women will return to Salt Lake City a week before the conference to complete the installation of the network.

“We are estimating that SCinet will be outfitted with a massive 3.5 Terabits per second (Tbps) of bandwidth for the conference and will be built from the ground up with leading edge network equipment and services (even pre-commercial in some instances) and will be considered the fastest network in the world during its operation,” said Corby Schmitz, SC16 SCinet Chair.

The WINS participants will support a wide range of technical areas that comprise SCinet’s incredible operation, including wide area networking, network security, wireless networking, routing, network architecture and other specialties.

“While demand for jobs in IT continues to increase, the number of women joining the IT workforce has been on the decline for many years,” said Marla Meehl, Network Director from UCAR and co-PI of the NSF grant. “WINS aims to help close this gap and help to build and diversify the IT workforce giving women professionals a truly unique opportunity to gain hands-on expertise in a variety of networking roles while also developing mentoring relationships with recognized technical leaders.”

Funds are being provided by the NSF through a $135,000 grant and via direct funding from ESnet supported by Advanced Scientific Computing Research (ASCR) in DOE Office of Science. Funding covers all travel expenses related to participating in the setup and operation of SCinet and will also provide travel funds for the participants to share their experiences at events like The Quilt Member Meetings, Regional Networking Member meetings, and the DOE National Lab Information Technology Annual Meeting.

“Not only is WINS providing hands-on engineering training to the participants but also the opportunity to present their experiences with the broader networking community throughout the year. This experience helps to expand important leadership and presentations skills and grow their professional connections with peers and executives alike,” said Wendy Huntoon, president and CEO of KINBER and co-PI of the NSF grant.

The program also represents a unique cross-agency collaboration between the NSF and DOE.  Both agencies recognize that the pursuit of knowledge and science discovery that these funding organizations support depends on bringing the best ideas from people of various backgrounds to the table.  

“Bringing together diverse voices and perspectives to any team in any field has been proven to lead to more creative solutions to achieve a common goal,” says Lauren Rotman, Science Engagement Group Lead, ESnet. “It is vital to our future that we bring every expert voice, every new idea to bear if our community is to tackle some of our society’s grandest challenges from understanding climate change to revolutionizing cancer treatment.”
