Project Grant 2212390

This four-year, $1.2 million Project Grant from the National Science Foundation's Division of Computer and Network Systems, under the Computer and Information Science and Engineering program (CFDA 47.070), will support the design and deployment of customized congestion control algorithms to enhance internet application performance. Specifically, the awardee, Carnegie Mellon University, will develop an ultra-low latency congestion control algorithm tailored for online video games using cross-layer optimizations. It will also conduct large-scale measurement studies to identify existing algorithms in use and test whether new and existing algorithms equitably share internet bandwidth. Finally, the university will provide recommendations for the design of future algorithms that can optimize application performance while avoiding unfriendly behavior toward competing internet connections. The award reflects NSF's mission to support investigator-initiated research and education in all areas of computing, communications, and information science and engineering.
