Snabb Switch simple and fast packet networking
summary
Open-source toolkit that runs on x86 servers and claims 100 Gbps per server by combining Lua + LuaJIT with custom user-space drivers (Intel 10G), a circular-buffer link model, and a pull/push “breathing” event loop. Implements vhost-user for QEMU, a pcap filter compiler, and a packet-blaster that can generate line-rate traffic (even 64‑byte packets) using a single core. Project targets NFV/OpenStack integration, keeps core under ~10k lines and a 1MB single binary, and reports successful real-world 100G+ deployments.
