ESnet Staff to Host Hands-on perfSONAR Workshop at Grace Hopper Conference

Esnet’s Sowmya Balasubramanian and Mary Hester will present a workshop on “Exploring an Open-Source Software on Miniature Computers” at the 2015 Grace Hopper Celebration of Women in Computing to be held Oct. 14 – 16 in Houston, Texas. Balasubramanian is a software developer for the Advanced Network Technologies Group at ESnet and Hester is a member of ESnet’s Science Engagement Team.

The Oct. 15 workshop attendees will explore the free, open-source software perfSONAR (Performance focused Service Oriented Network monitoring Architecture). Co-developed by ESnet, perfSONAR is a network monitoring and measurement tool to help network and IT staff understand and visualize packet loss and throughput problems on network connections through active testing and publishing of the data. The workshop will simulate a world-wide network of servers to troubleshoot and explore networking on small single-board computers.

ESnet, Collaborators Release Latest Version of perfSONAR Network Measurement Software


To propel the automation and deployment of large-scale distributed monitoring infrastructures across the Research and Education (R&E) community, ESnet, GEANT, Indiana University, and Internet2 announced the release of perfSONAR v3.5. perfSONAR is a widely deployed test and measurement infrastructure that is used by science networks and facilities around the world to monitor and ensure network performance.

Released Oct. 5 at the Internet2 2015 Technology Exchange in Cleveland, the perfSONAR updates include support for accelerating the deployment of nodes within a campus or enterprise, improves the security profile of perfSONAR nodes, and reduces network operations center (NOC) integration costs.

ESnet Releases Open Source Software from MyESnet Portal for Building Online Interactive Network Portals

When ESnet, the Department of Energy’s (DOE) Energy Sciences Network, unveiled its online interactive network portal called MyESnet in July of 2011, the reaction was strongly positive – other research and education networks liked it so much, they wanted the code to create their own portals.

After four years of development and refinement, they will get their wish. On Oct. 5, Jon Dugan of ESnet’s Tool Team will give a presentation on “ESnet’s Network Visualization Toolkit” at the 2015 Technology Exchange conference in Cleveland, Ohio. About 500 network experts from around the world are expected to attend the meeting.

“People really appreciate MyESnet, which we think is a great visualization of the network and network data. We have received a lot of queries from the community to help them create a similar portal,” said ESnet Chief Technologist Inder Monga, who leads the Tools Team. “So as a way of giving back to the community, we are releasing as open source three software libraries we developed that provide critical components to create the portal.”
