Assistant Professor of Computer Science Ranysha Ware received the 2025 SIGCOMM Doctoral Dissertation Award at the ACM SIGCOMM conference in Coimbra, Portugal. Ware's award winning dissertation, "Battle for Bandwidth: On The Deployability of New Congestion Control Algorithms," charts new ways to think about a longstanding question: what makes a congestion-control scheme safe and advisable to deploy on a multi-agent network?

The award is the highest honor given to a dissertation in the field of computer networking worldwide. Her dissertation focused on how fairly or unfairly internet services share bandwidth.

Ware’s work sparked headlines in the press, including Vice, when she discovered that Google’s congestion control algorithm, called BBR (Bottleneck Bandwidth and Round-trip propagation time), was mathematically and provably unfair to other algorithms. Google, surprised by the discovery, quickly patched the problem and funded the next chapter of Ware’s work.
