Tianyi Gao

I am Tianyi Gao (高天怡), a PhD student in the School of Informatics at the University of Edinburgh, supervised by Prof. Michio Honda. I completed MSc in Computer Science (Class Prize) at the University of Edinburgh in 2022, and my BSc in Computer Science with Artificial Intelligence at the University of Nottingham in 2021. I have also interned under Prof. Guangyu Sun at the Advanced Institute of Information Technology (AIIT), Peking University in 2020.

My research interests lie in designing high-performance and secure datacenter networking systems. I am currently working on SDT, a datacenter transport protocol with transport-level encryption. SDT is designed as a generic, secure transport that can provide strong confidentiality while maintaining low latency and high throughput for a wide range of datacenter applications. I have also contributed to XO, a framework for remote TCP connection offload that improves scalability and reduces host overhead.

I am always open to discussions and collaborations on research and open-source projects, please reach out!

Efficient resource utilization in server clusters is essential for maximizing service capacity and minimizing latency while reducing infrastructure costs, whether in edge clouds or hyperscale deployments. Current approaches face significant limitations: layer 4 load balancing (L4LB) alone causes load imbalance over time with long-lived connections, while layer 7 load balancing (L7LB) introduces substantial CPU, memory, and network overhead despite enabling fine-grained server selection based on application-level requests.This paper presents XO, a set of concept and techniques to enable a TCP server to offload entire TCP connection and application-request processing to another machine at request granularity. Together with L4LB, XO achieves L7LB-level load distribution without the associated overheads.
