Kernel-Bypass

• Kernel Bypass Networking: DPDK, io_uring, and the RDMA Revolution · 2025-02-10

  Dive into how modern systems escape the kernel networking stack for microsecond-scale performance: DPDK's poll-mode drivers, io_uring's submission rings, RDMA's one-sided operations, and the trade-offs each approach demands.

• User-Space Networking: Snabb Switch, FD.io VPP (Vector Packet Processing), AF_XDP, and the Philosophy of Kernel Bypass · 2021-05-14

  A deep exploration of user-space networking — how Snabb, VPP, and AF_XDP achieve line-rate packet processing by bypassing the kernel, and the architectural trade-offs of moving the network data plane into user space.
