AccelTCP: Accelerating Network Applications with Stateful TCP Offloading
summary
Hardware-assisted design that runs TCP protocol logic on programmable NICs and keeps a minimal host stack, offloading connection setup/teardown and running stateful TCP offloading on the NIC. It implements zero DMA splicing so relayed payloads never traverse host memory, reduces TCP management cycles that consumed 60% CPU for short connections, makes short-lived connections perform like persistent ones, and shows real gains: Redis 2.3x and HAProxy 11.9x throughput improvements in their evaluation.
