About Me

I am a fourth-year Ph.D. candidate in the Mobile Systems and Networking (MSN) Group (opens new window) of the SONIC Laboratory, School of Computer Science at Fudan University, advised by Prof. Xin Wang (opens new window) and Prof. Yang Chen (opens new window). My research interests include Machine Learning for Networking Systems (NetAI), Next-Generation Internet Architecture, and Social Network Analysis.

I graduated from Lanzhou University in 2019 with a B.S. in Computer Science.

  • FlexHTTP: An Intelligent and Scalable HTTP Version Selection System. Proc. of the 2nd workshop on Machine Learning and Systems (EuroMLSys), co-located with EuroSys'22.

    Mengying Zhou, Zheng Li, Shihan Lin, Xin Wang, and Yang Chen.

Our work find that under different network conditions and web page structures, neither HTTP/2 nor HTTP/3 can always perform better. Motivated by this finding, we propose FlexHTTP, an intelligent and scalable HTTP version selection system. The proof-of-concept evaluation demonstrates that FlexHTTP almost achieves an optimal HTTP version selection with a hit ratio of 0.97. When compared with the ideal results, FlexHTTP only displays a small gap with a value of 30ms median Speed Index.

  • Polygon: A QUIC-Based CDN Server Selection System Supporting Multiple Resource Demands. Proc. of the 22nd ACM/IFIP Middleware Conference (Middleware’21), Industry Track, Virtual Event, Canada, Dec. 2021.

    Mengying Zhou, Tiancheng Guo, Yang Chen, Junjie Wan, and Xin Wang.

Our work find that requests in different application scenarios would have different resource type priorities. And motivated by this finding, we propose Polygon, a QUIC-based CDN server selection system supporting multiple resource demands. It shows a significant improvement in job completion time and resource utilization efficiency.

Determining the physical locations of CDN Points of Presence (PoPs) is fundamental to understanding and diagnosing CDN services. Yet, the popular deployment of IP Anycast in CDNs has rendered existing geolocation tools unreliable. To fill this gap, we present an HTTP-based solution that leverages subtle geographic hints in HTTP responses to locate CDN PoPs at the city-level granularity. The evaluation shows that our technique achieves over 90% accuracy with an average error distance of less than 40 km.
