ESnet, Berkeley Lab to Host Feb. 27-28 Workshop on Operating Innovative Networks

The next installment of the Operating Innovative Networks (OIN) workshop series will be held Feb. 27-28 at Lawrence Berkeley National Laboratory, drawing 50 university and laboratory network engineers from as far away as New Jersey, Texas, Illinois and Colorado. The workshop is co-hosted by ESnet, Berkeley Lab and CENIC, the Corporation for Education Network Initiatives in California. The program is designed to give attendees the knowledge and training needed to build next-generation campus networks that are optimized for data-intensive science. 

 Presented by experts from the Department of Energy’s ESnet, Indiana University and Internet2, the workshop series will focus on Science DMZnetwork architectures, perfSONAR performance measurement software, data transfer nodes and emerging software defined networking techniques. Combined, these technologies are proven to support high-performance, big data science applications, including high-volume bulk data transfer, remote experiment control, and data visualization. The workshops will consist of two days of presentation material, along with hands-on sessions to encourage immediate familiarity with these technologies.

 The Berkeley workshop is the fourth in the series and future sessions are planned in Atlanta (March), Boston (May) and Oregon (July). Read more at:

ESnet’s Greg Bell: Better Networking Helps Federal Agencies Better Fulfill Missions

In a Feb. 20 presentation given to government network providers during a one-day workshop on “Scaling Networks Securely and Cost Effectively” in Washington, D.C, ESnet Director Greg Bell told his audience that improvements to network infrastructure can help agencies better meet their missions. According to an article about his talk in Federal Computer Week, Bell said that common problems like “naively configured firewalls, lossy networks” – things like poor cabling, for example – and poorly configured end-systems hinder network speed. These kinds of problems are a much simpler fix than alternatives such as costly improvements to the physical network.

ESnet partners with eduPERT for TERENA Networking Conference Training

ESnet, in collaboration with the GÉANT eduPERT team, will conduct a training session at the annual TERENA Networking Conference, May 18-19, in Dublin Ireland.  This training will introduce performance monitoring and troubleshooting concepts using the perfSONAR measurement framework, along with network architecture designs including the Science DMZ.  Registration for this event is available via the TNC conference web site:


ESnet’s Greg Bell to Give Keynote at Feb. 20 Event for Government Networking, IT Pros

ESnet Director Greg Bell will give the keynote talk on “Networking for Discovery” at Scaling Networks Securely and Cost Effectively, a one-day program organized by Government Computer News, Federal Computer Week and Ciena that is targeted at government network providers and IT staff. The event will be held Thursday, Feb. 20, at the National Press Club in Washington, D.C.

In this program, technology experts and government leaders will provide their thoughts and strategies on delivering the infrastructure that will enable the future of big data computing. Bell’s talk will focus on ESnet’s approach to providing high performance networks to support the growing trend of big science data. He will also discuss ESnet’s work in researching and developing new Internet technologies to support big data growth over time.

ESnet’s Brian Tierney Discusses Network Performance in HPCwire Podcast

In an interview with HPCwire editor Nicole Hemsoth, Brian Tierney, leader of the ESnet Advanced Network Technologies Group at  ESnet’s 100G Network Testbed Project, discusses network performance issues, including the 1,000th deployment of the perfSONAR network measurement software.

In the 20-minute  interview, Brian talks about how he originally got interested in network performance, the current state of ESnet and how institutions can assess and improve the performance of their network connections, such as referring to the knowledge base. He also describes how Science DMZs can safely transfer massive datasets around firewalls and touches on the potential of Software Defined Networking.
