How Baidu Cloud’s Sonata Achieves Predictable Performance Across Multi‑Vendor, Multi‑Generation NICs (NSDI’27)

The paper presents Sonata, a software‑centric vSwitch data plane that decouples from specific NICs, enabling a single implementation to handle heterogeneous, multi‑generation hardware while delivering 2.13‑2.51× software CPS gains and an additional 4.3‑11.5× boost with hardware offload, all validated on hundreds of thousands of production servers.
