PFQ
A functional network framework for Linux enabling high-performance packet capture, transmission, and in-kernel processing optimized for multi-core systems.
What is PFQ?
PFQ is a functional network framework for Linux that enables high-performance packet capture, transmission, and in-kernel processing at multi-gigabit speeds. It solves the challenge of efficient network traffic handling on multi-core systems by providing lock-free architectures, kernel-bypass techniques, and a functional language for early-stage packet processing.
Network engineers, researchers, and developers building high-performance network applications, monitoring tools, or custom packet processors on Linux, especially those working with 10G/40G+ links and multi-core hardware.
Developers choose PFQ for its unique combination of functional programming in the kernel (via pfq-lang), lock-free multi-core optimization, and compatibility with existing NIC drivers, allowing acceleration of both new and legacy applications without hardware modifications.
