Since July 2022, I have been working in the Computing-Network Integration Research Group of Shandong Computer Science Center (National Supercomputer Center in Ji'nan), China. From October 2024 to October 2025, I am a visiting scholar in Professor James Won-Ki Hong's DPNM Lab at Pohang University of Science and Technology, Korea. From April 2021 to June 2022, I worked as a R&D intern in the High-Speed Network Team of ByteDance, working on RDMA/RoCE under the leadership of Dr. Zhuo Jiang. In June 2022, I received my Ph.D. degree from the National Engineering Research Center of Advanced Network Technologies, Beijing Jiaotong University. In June 2017, I received my Bachelor of Engineering degree in Communication Engineering and my Bachelor of Laws degree from Shandong Normal University. My research interest is the Network Measurement, Testing and Management, especially Software-defined Networks and Data Center Network. These all serve the National Supercomputing Internet, which is a project that explore how to combine high-performance computing (supercomputing) with wide-area computer networks.
SRv6-based active network telemetry architecture and its path planning strategy (CIA, 2019), Telemetry flow selection method based on multi-objective optimization and its orchestration solver based on non-dominated sorting genetic algorithm (APNOMS, 2021), A review of in-band network telemetry research (COMNET, 2021), The discovery and detection mechanism of in-band network telemetry missing-information FindINT (IEEE NETLETT, 2021), In-band network telemetry quality diagnosis and missing information recovery algorithm LossSight (IEEE TNSM, 2021), ByteDance intra-host delay monitoring and fault diagnosis system Hostping (NSDI, 2023).
The prototype of the Software-defined Network Impairment Emulator (ZL202320329297.0, ZL202310224941.2, 2023), including (1) intent-driven network impairment configuration (ZL2023117778457.0, 2023), (2) serial-parallel impairment function combination (HPCC, 2024), and (3) CPU-Tofino collaborative functions implementation, which meets the functional and performance requirements of network impairment emulation, improves the definability of network impairment emulation, and effectively reduces the cost and overhead of network testing.
