Snabb Switch simple and fast packet networking

on YouTube ↗32m

" summary

Snabb Switch is an open‑source toolkit that runs on x86/Linux servers and claims line‑rate networking up to tens or hundreds of Gbps per box by using per‑core event loops, a tiny packet struct (10 KB buffer + length), and a 3‑primitive model: apps, links, packets. It uses LuaJIT for almost all code, ships as a ~1 MB single binary and targets <10k LOC, implements its own Intel 10G driver and a vhost‑user VM path, and demonstrates a packet blaster that can generate ~100 Gbps with one core.
