Welcome to Chuanxiong Guo's homepage!

I am a Director of the AI Labs of Bytedance Inc, a global information distribution platform that connects people and information. Before that I was a Principal Researcher at Microsoft Research Redmond. I spent several years as a Principal Software Engineering Manager at Microsoft Azure before I moved back to MSR. I was a Senior Researcher at Microsoft Research Asia before I joined Microsoft Azure.

My areas of interest include networked systems at large-scale, data center networking (DCN), machine learning system, systems availability and troubleshooting, and cloud computing.

I am among the first to work on data center networking research. I have won several best paper awards for my research in data center networking. I have won several MSR technology transfer awards and the MSR Redmond Labs Exemplary Collaboration Award 2017 for technology transfers. Several of my envisions including DCN virtualization, DCN monitoring, and ServerSwitch generated both academic and industrial impacts. Many of the systems that I have designed and built, including CloudBrain, RDMA/RoCEv2, Pingmesh, NetBouncer, DiffServ for data centers, are deployed in Microsoft Azure and Bing data centers in millions of servers. RDMA/RoCEv2 and Pingmesh in particular are widely adopted by the industry.

I am currently working on machine learning systems, data center networking, and system availability.
