Mohammad Alizadeh, Massachusetts Institute of Technology, is the recipient of the 2022 ACM Grace Murray Hopper Award for pioneering and impactful contributions to data centre networks. Alizadeh has fundamentally advanced how data centres communicate efficiently in transporting data. One of his key contributions is the control of data centre network congestion and packet loss with a ground-breaking Data Centre Transport Control Protocol (DCTCP). DCTCP significantly increases performance in datacentre environments where state-of-the-art TCP protocols fall short. The theoretical foundation upon which DCTCP is built and the empirical analyses, novel algorithms, and explicit congestion notification techniques it leverages enable data packets to circumvent congestion while using significantly less buffer space.
