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.

Algorithmic Complexity Attacks (ACAs) are a powerful class of denial of service attack where a resource-strapped attacker can, using a small amount of attack traffic, nonetheless overload a highly provisioned server. Today at SIGCOMM 2022, Nirav Atre demonstrated a new approach called SurgeProtector that can mathematically guarantee that a system is safe from ACAs. Read a summary of the work from Cylab, dig into the code, or read the research paper to learn more.

When wireless networks suffer sudden throughput degradation, queues build up rapidly at APs and degrade applications like video conferencing. Today at SIGCOMM 2022, Zili Meng shows how wireless APs can quickly signal to senders to slow down transmission when throughput degrades; improving tail network latency and making videos play out smoother. You can read about Zili’s system Zhuge here.

Systems like SurgeProtector and many others rely on heuristics to predict job sizes in order to implement shortest-job-first scheduling. However, heuristics are not always correct which can lead to error in the systems that use them. Today at SIGCOMM 2022, undergraduate Erica Chiang presented a poster on her work on Robust Heuristics for SurgeProtector and took second place in the SIGCOMM Undergraduate Student Research Competition. Congratulations, Erica! Read more on Erica’s work here.
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, a Google Faculty Research Award, 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.
