emmericp/MoonGen
MoonGen is a fully scriptable high-speed packet generator built on DPDK and LuaJIT. It can saturate a 10 Gbit/s 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. observed · 2026-08-28

MoonGen is a scriptable high-speed packet generator built on DPDK and LuaJIT that can saturate 10 Gbit/s Ethernet links with 64-byte packets on a single CPU core. All packets are crafted in real time by user-provided Lua scripts, with hardware-based timestamping and precise rate control.
Use cases
- generate high-speed network traffic to saturate a 10 Gbit/s link
- benchmark firewalls and middle-boxes with custom traffic patterns
- measure latency with sub-microsecond hardware timestamping
- test packet loss in a system under test
- script custom per-packet traffic generation in Lua
- generate precise traffic patterns for network experiments
When to choose
- you need line-rate packet generation with per-packet scripting flexibility
- you require precise hardware timestamping and rate control on commodity hardware
- you want to benchmark network devices or middle-boxes with custom test scripts
When to avoid
- you need a simple GUI-based traffic generator
- your tests run on non-Linux platforms
- you only need low-rate traffic without precise timing
