Summer at ESnet: the view from our students: Part 1

Summer students are a key part of growing ESnet and supporting the scientific networking community. Every year, we host research projects with talented students working on important research topics. We benefit tremendously from their enthusiasm, talent, and fresh ideas, and they work directly with our staff across a wide set of disciplines.  Here are some thoughts from two current students on what it is like to work with ESnet, and what research excites them.

Sandesh Dhawaskar Sathyanarayana:

I am thrilled with my summer internship at ESnet. During my Multipath Transmission Control Protocol (TCP) research, I used in-kernel programs to implement receiver-based network controllers and have always wanted to work more on it as it allows one to hook into the kernel and innovate the different network protocols. Software Defined Networking (SDN) along with dataplane and kernel network programming is trending as it enables the telecom world to save billions of dollars and operate the network more efficiently. 

My goal for this summer was to work and innovate in the SDN field, and ESnet was the perfect fit for it. At ESnet, I work on the Q-factor project using technologies such as eBPF (extended Berkeley Packet Filters) and XDP (eXpress Data Path) to improve data transfer speeds in science networks. I get to play with the state-of-the-art P4 dataplane programming language for switches and programmable NICs. The project is a collaboration with Florida International University (FIU), so I get to work with amazing people. Our team is small, with great mentors like Richard Cziva and Jeronimo Bezerra. 

What I love the most is the freedom to think and solve problems with great support. Having to work in different labs, I used to be stressed most of the time to complete the work. This summer has been a very different experience with excellent mentorship. I also had other offers and chose ESnet as my advisor and co-advisors insisted strongly, and I am happy I went with ESnet.

Elias Joseph:

Interning at ESnet has been a really good learning experience for me. The regular seminars from researchers in the lab about their current projects have allowed me to learn about a lot of topics I usually wouldn’t have much exposure to, as well as see how the concepts I have learned about in school are being applied in a professional environment. It is really interesting to see how machine learning is actively being used at the laboratory, and what current advancements are being made with it.

As much as I’m learning from the seminars, I’m learning even more from the project I’m working on. This internship is giving me experience using a lot of tools that are prevalent in computer science but are underutilized in my master’s program, and my mentor has been extremely helpful in getting me up to speed on these tools.

I’ve also found working on my project very fulfilling. Primarily I’ve been working on a tool that displays internet traffic, as well as predictions for future traffic, and seeing it come together over the past month and a half has been really cool.

I do miss the social aspect of working in an office, but the networking and social activities that have been organized have done a lot to alleviate that, and overall, I have grown a lot in the first half of my internship.

ESnet History on (virtual) Display

As part of LBL’s The Next 90 campaign, new features on the past, present and future of the Computing Sciences Area (CSA) and ESnet have just been released!

From the first documented demonstration of 10 gigabit Ethernet in 2002….

For a vision of where we, and all of CSA, started back in the 1990s, including a video of early ESnet telecommuting experiments well before Zoom, please see this link.

3 Questions with Katrina Turner

Three questions with a new staff member! Aloha, Katrina!

Katrina hails from Kāne’ohe, Hawai’i where she was born and raised. She recently graduated from the University of Hawai’i at Mānoa with an M.S. in Computer Science and is now with ESnet’s Software Engineering Management and Analysis Group.  Katrina loves her island life and enjoys dancing hula, hiking, and going to the beach.  She also loves both playing and making video games in her spare time.

What brought you to ESnet?

During my time as a Research Assistant at UH Mānoa, I had the opportunity to work with some of ESnet’s team members and I really admired both the work they did as well as the work culture they were a part of.  When I heard there were openings at ESnet, I jumped at the chance to continue working with such awesome people!

What is the most exciting thing going on in your field right now?

In recent years, Data Visualization has become more popular with the general public, being shared through social media and used by the masses instead of only scientists and analysts.  As a result, we are seeing really creative and interesting ways of showing data beyond the standard charts.  Also, the integration of machine learning to allow us to easily visualize large amounts of data is really exciting.

What book would you recommend?

If you like Fantasy Fiction, the Sword of Truth series by Terry Goodkind is great, but definitely a time commitment. I also just started reading The Windup Girl.
