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.
