In particular, he supervised Ion Stoica’s 2001 award-winning Ph.D. dissertation on Internet QoS. In addition, his End System Multicast (ESM) research group at CMU pioneered the overlay multicast architecture and developed the world’s first peer-to-peer live streaming system. His papers have thrice won Test of Time Awards from the Association for Computing Machinery (ACM). Most recently, he won in 2022 for his 2011 paper detailing the direct connection between video quality and user engagement. Prior he won the ACM SIGMETRICS Test of Time Awards in 2011 for his paper on End System Multicast (ESM) and its significant impact on research, methodology, application, and transfer in the last decade. He won again in 2015 for his 2005 4D research project which advocated the network control architecture that separates control logic from data devices, and was the precursor to the Software Defined Networks (SDN) initiative.

Hui was elected to be a Fellow of ACM in 2006 and received the Alfred Sloan Fellowship in 2000. He received the National Science Foundation Career Award in 1996 and held the Finmeccanica Chair in Computer Science at CMU from 1998 to 2001.
