moongen: fully scriptable high-speed packet generator

MoonGen is a fully scriptable high-speed packet generator built on DPDK and LuaJIT. It can saturate a 10 GBit connection with 64 byte packets on a single CPU core while executing user-provided Lua scripts for each packet.

Multi-core support allows for even higher rates. It also features precise and accurate timestamping and rate control
