My current projects target frequently-used or centralized components of distributed data center systems, where the performance of the entire system will improve substantially by improving the performance of these components.

Fast Data Center Transport

Remote procedure call (RPC) is the glue that holds modern microservice architectures together. Because a single user request might require coordination among hundreds of machines, the network stack plays a large role in the overall latency, throughput, and CPU utilization of requests. RPCs are commonly run over TCP, which is general-purpose and provides nice guarantees, but has been shown to be inefficient. I am currently leading a project (in collaboration with Christopher Hodsdon) to design a transport layer tailored to the particular use patterns and needs of RPC. In doing so, we aim to reduce server-side CPU utilization, reduce end-to-end request latency, and increase overall application throughput for services that use RPC.


Sequencers are centralized servers that hand out numbered tokens to clients so that clients can order their operations in a distributed system. This project, led by fellow PhD student Christopher Hodsdon, uses a custom transport layer and sequencer design to serve clients at line rate and recover quickly from communication and sequencer failure.
