Kernel Bypass Networking: DPDK, io_uring, and the RDMA Revolution
2025-02-10Dive 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
2021-05-14A 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.
