Reverie: Low Pass Filter-Based Switch Buffer Sharing for Datacenters with RDMA and TCP Traffic

Reverie: Low Pass Filter-Based Switch Buffer Sharing for Datacenters with RDMA and TCP Traffic

Explore a 15-minute conference talk from USENIX NSDI '24 that introduces Reverie, a novel buffer-sharing scheme for datacenters with RDMA and TCP traffic. Learn how this approach addresses the limitations of current buffer-sharing practices by using a unified admission control and low-pass filter-based allocation. Discover how Reverie improves performance for both lossless and loss-tolerant traffic classes, potentially reducing flow completion times by up to 33%. Gain insights into the challenges of managing switch buffers in modern datacenters and understand the innovative solution proposed by researchers from TU Berlin, Microsoft Research, and Princeton University.
