The Wireless and Networking group at Microsoft Research Asia engages in fundamental research on all aspects of computer networking. Our group members’ research interests span cloud computing, datacenter networks, wireless, and mobile systems. We investigate new paradigms to build intelligent cloud infrastructure and networks. We emphasize both analytical and empirical approaches, and build running systems to validate theoretical results and refine system principles from experimental work.
Data Center Networking — building efficient and intelligent fabrics for millions of servers
Data center networking (DCN) is a crucial part to support efficient operations of online services in the cloud. We investigate paradigm-shifting technologies to build high availability, high reliability and high-performance network fabric for our data centers.

FPGA for the cloud — empowering the cloud with reconfigurable hardware
We foresee that the re-configurability and high parallelism of FPGA will fundamentally change the way we are serving online services. We are investigating the cutting-edge technologies for better programming FPGAs and empowering our services in the cloud. We have demonstrated that using FPGA can significantly accelerate Deep Neural Networks in the cloud.

Software radio — empowering wireless revolution with the magic of software
We foresee that the increasingly powerful multi-core architecture and parallel data processing will fundamentally change wireless communications. Software-based cognitive wireless systems will become much more powerful, flexible, and efficient compared with existing wireless technologies. The enabling technology is software radio (or software-defined radio, SDR). For the past several years, we have strike to build the best software radio in a very different way, and to develop programming models and tools that will greatly reduce the effort involved in implementing state-of-the-art wireless systems.

Wireless Networks — computational thinking in the traditional field
The explosive increase in mobile usage demands constant revolutions in wireless technology. We have been engaged in a broad range of wireless research in PHY, MAC, cross-layer, MIMO, dynamic spectrum, whitespace, measurement, reliability, etc. Our approach has been one with “computational wireless” — applying computer science methodology in a very traditional field.
