" summary

Open-source Snabb Switch is a Linux/x86 toolkit that targets line-rate packet processing and claims 100 Gbps per server by minimizing kernel crossings and using a Lua-based pipeline of small apps, buffers and links. Concrete builds include a traffic generator, virtual NICs for NFV/OpenStack, and user-space drivers and filters; tests report 10 million packets/sec and support for jumbo frames (~9500‑byte MTU), running at line rate on commodity servers.
