NSF Funds Upgraded Network Linking Labs, Universities and Research Networks Based on Science DMZ

For the last three years, the National Science Foundation (NSF) has made a series of competitive grants to over 100 U.S. universities to aggressively upgrade their campus network capacity for greatly enhanced science data access, with many incorporating ESnet’s Science DMZ architecture. NSF is now building on that distributed investment by funding a $5 million, five-year award to UC San Diego and UC Berkeley to establish a Pacific Research Platform (PRP), a science-driven high-capacity data-centric “freeway system” on a large regional scale.

The PRP is basing its initial deployment on a proven and scalable network design model for optimizing science data transfers developed by ESnet. “ESnet developed the Science DMZ concept to help address common network performance problems  encountered at research institutions by creating a network architecture designed for high-performance applications, where the data science network is distinct from the commodity shared Internet,” said ESnet Director Greg Bell. “As part of its extensive national and international outreach, ESnet is committed to working closely with the Pacific Research Platform to leverage the Science DMZ and Science Engagement concepts to enable collaborating scientists to advance their research.”

In the PRP the Science DMZ model will be extended from a set of heterogeneous campus-level DMZs to an interoperable regional model. Read more.

ESnet, Internet2, NITRD Holding 3-Day Roadmap to Operational SDN Workshop

This week ESnet is hosting a three-day workshop to develop a “Roadmap to Operational Software Defined Networking-based networks,” with participants from other research and education networks, universities, government agencies, international networks and networking equipment vendors. Software defined networking, or SDN, is an approach that allows network administrators to manage network services by decoupling various levels of network functionality, enabling more flexibility in moving data and meeting application requirements.

The July 14-16 workshop at Berkeley Lab will include short presentations on the “state of the union” of various SDN deployments at universities, networks and national labs, as well as at ESnet. After a day-and-a-half of presentations, attendees will form breakout groups to assess how can the community work with the open source software community and vendors to tackle the SDN operational gaps and to develop a roadmap to SDN deployments. The third day of the workshop will focus on security related issues to SDN.

Organized by ESnet, Internet2, DOE, the National Science Foundation and the Networking and Information Technology Research and Development (NITRD) Program, the workshop is expected to draw 70 attendees in person. Those not attending can access the workshop via Zoom at, and joining # 510 486-4100.

ESnet’s Monga to Speak at UK Workshop on Using SDN to Build Smarter Cities

Inder Monga, ESnet’s chief technology officer, will give a keynote talk on “SDN Opportunities in Smart Cities” at a July 7 workshop on The Software Defined Network – Programmable City. The workshop, to be held in Bristol, England, is sponsored by Bristol Is Open and the Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating the adoption of open software-defined networking (SDN).

According to the organizers, the emergence of smart technology in cities such as Bristol, is generating many Internet of Things (IoT) requirements that industry organizations like ONF will implement in future protocol development. As one of the leaders in liveable smart cities, Bristol will be an important resource for ONF, as a source of information in the development of future IoT specific standards.

Monga is an internationally recognized leader in SDN and has given talks on the subject at meetings around the globe and is an ONF research associate. In recognition of ESnet’s leadership in SDN, Monga was asked to organize a two-day workshop in Washington, D.C. in December 2013 to plan a path forward to develop, deploy and operate a prototype SDN network.

Open Networking Foundation Unveils Atrium, an Open SDN Software Distribution

Atrium, an open software distribution for SDN (software defined networking), has been released by the Open Networking Foundation (ONF). ESnet is among the contributors to the software release and ESnet Chief Technologist Inder Monga is an ONF research associate. Atrium is designed to help the networking industry as a whole more easily adopt open SDN by integrating established open source SDN software with some critical connecting pieces. Read the Atrium news release.

ESnet’s work with the ONF reflects the network’s strong role in advancing SDN, which goes back to the development of OSCARS, the On-demand Secure Circuits and Advance Reservation System, an advanced software system for booking time and resources on high-speed science networks.

In recognition of ESnet’s leadership in SDN, ESnet’s Monga was asked to organize a two-day workshop in Washington, D.C. to plan a path forward to develop, deploy and operate a prototype SDN network. The December 2013 invitation-only workshop, co-sponsored by DOE, Networking and Information Technology Research and Development (NITRD) and the National Science Foundation, drew about 100 networking experts from academia, industry, national labs and federal agencies.

Here are some other examples of ESnet’s role as a leader in SDN.

In May 2015, ESnet was a member of a team deploying an ONOS-based software-defined peering router at AARNet/CSIRO in Australia which exchanged routes with the Vandervecken software-defined networking (SDN) controller stack at ESnet in California. The project successfully exchanged 15,000 routes on a trans-Pacific network link. Read more about this global SDN breakthrough.

In February 2015, ESnet was honored by the Corporation for Education Network Initiatives in California (CENIC) as a recipient of the 2015 Innovations in Networking Award for High-Performance Research Applications for their 100-Gigabit Software-Defined Networking (100G SDN) Testbed. The ESnet 100G SDN Testbed provides network researchers with a realistic environment for testing 100G application/middleware experiments. It also supports several 10G paths for SDN experiments, and will be significantly enhanced this summer with new OpenFlow v1.3 hardware. Read more.

In November 2013, ESnet joined Brocade and Infinera in an online demonstration of how SDN can be used to provision services and automatically optimize network resources across a multi-layer network as traffic and service demands change. The demonstration leveraged ESnet’s OSCARS application. Read more.

And in December 2012, ESnet and Infinera demonstrated a prototype SDN Open Transport Switch (OTS) capable of dynamically controlling bandwidth services at the optical layer. The proof-of-concept demo was conducted on a testbed network ring in New York, connecting Brookhaven National Laboratory with a network hub in Manhattan. The demonstration marked the first time an open architecture with SDN was used to provide traffic-engineered paths at the optical layer and was accomplished through extensions to the OpenFlow protocol.
