PFQ v6.2
PFQ is a functional framework designed for the Linux operating system built for efficient packets capture/transmission (10G, 40G and beyond), in-kernel functional processing, kernel-bypass and packets steering across groups of sockets/end-points. It is highly optimized for multi-core architecture, as well as for network devices equipped with multiple hardware queues. Compliant with any NIC, it provides a script that generates accelerated network device drivers starting from the source code. PFQ enables the development of high-performance network applications, and it is shipped with a custom version of libpcap that accelerate and parallelize legacy applications. Besides, a pure functional language designed for early stages in-kernel packet processing is included: pfq-lang. Pfq-Lang is inspired by Haskell and is intended to define applications that run on top of network device drivers. Through pfq-lang it is possible to build efficient bridges, port mirrors, simple firewalls, network balancers and so forth. The framework includes the source code of the PFQ kernel module, user-space libraries for C, C++11-14, Haskell language, an accelerated pcap library, an impl
