Poster: Pushing RDMA into Milliseconds RTT Communication

Published: 09 December 2024 Publication History

Abstract

Thanks to its high performance and efficiency, RDMA has become an essential networking primitive in today's datacenter. However, existing RDMA-based systems mainly focus on accelerating data communication of endpoints away from each other in tens or hundreds of microseconds RTT. This paper aims to address the following question: How far can RDMA be employed without losing its performance and efficiency merit? We present our methodology and analysis to study the potential of RDMA networking over a millisecond-scale RTT path.
