The National Science Foundation (NSF) awarded a $959,491 Project Grant under the CFDA 47.070 Computer and Information Science and Engineering program to The Johns Hopkins University in Baltimore, MD. The grant runs from October 1, 2023 to September 30, 2027. The research aims to develop new methods for fast and scalable congestion management in datacenter networks to improve the speed and reliability of cloud-based applications. Key objectives include analyzing the structural properties and origins of congestion events, and designing multi-scale congestion management techniques that can interoperate across different timescales. The project will build a measurement framework to systematically study the scaling of congestion and develop novel network management abstractions.
