I am a computer scientist interested in everything networked: from protocols and applications to the hardware that carries our data across the Internet. My goal is to make networks faster, more reliable, more secure, and lately, more fair and equitable.

Thank you to Intel for awarding an Intel Outstanding Researcher Award to the Pigasus faculty (James Hoe, Vyas Sekar, and myself) for our work on open-source intrusion detection at 100Gbps and beyond! Read the announcement here.

Internet services today are continuously innovating to provide the best performance for their services, including by developing new Congestion Control Algorithms (CCAs). However, these algorithms are often proprietary or unpublished – leaving the Internet community in the dark whether these CCAs are stable, fair, or efficient. Today at HotNets 2021, Margarida Ferreira presents a prototype called Mister880 that allows researchers to reverse engineer deployed CCAs using program synthesis.

One year ago at OSDI 2020, we published Pigasus – an FPGA-based IDS and the first open-source intrusion detection system to scale to 100Gbps with a single server. Today Pigasus is open-sourced, used in research at at least 7 universities, and in engagements with 4 companies. To connect this community and share the latest Pigasus-related updates, we started the Pigasus developers’ meeting which met today for the first time! Sign up to join future meetings at mail.pigasus-ids.org.

Congestion Control Algorithms (CCAs) determine important properties like fairness, utilization, and performance stability on the Internet. These properties are well-studied under the assumption that congestion occurs at the `edge’ of the network (such as home network links) – but what happens when congestion occurs in core Internet links as observed in recent studies? Adithya Philip provides some early insights into this question at IMC 2021 today. You can watch his talk or read the paper to learn more!

Research Talks


Justine Sherry is an assistant professor at Carnegie Mellon University. Her interests are in software and hardware networked systems; her work includes middleboxes, FPGA packet processing, measurement, cloud computing, and congestion control. Dr. Sherry received her PhD (2016) and MS (2012) from UC Berkeley, and her BS and BA (2010) from the University of Washington. Her research has been awarded the VMware Systems Research Award, the Applied Networking Research Prize, the SIGCOMM doctoral dissertation award, the David J. Sakrison prize, and paper awards at USENIX NSDI and ACM SIGCOMM. She is a member of the DARPA ISAT Study Group and the SIGCOMM CARES Committee. Most importantly, she is always on the lookout for a great cappuccino.
