PFQ - Functional Network Framework For Multi-Core Architectures

PFQ is a purposeful framework designed for the Linux working system constructed for environment friendly packets seize/transmission (10G, 40G and past), in-kernel purposeful processing, kernel-bypass and packets steering throughout teams of sockets/finish-factors.

It is extremely optimized for multi-core structure, in addition to for community units geared up with a number of {hardware} queues. Compliant with any NIC, it offers a script that generates accelerated community machine drivers ranging from the supply code.

PFQ permits the event of excessive-efficiency community functions, and it’s shipped with a customized model of libpcap that speed up and parallelize legacy functions. Besides, a pure purposeful language designed for early levels in-kernel packet processing is included: pfq-lang.

Pfq-Lang is impressed by Haskell and is meant to outline functions that run on prime of community machine drivers. Through pfq-lang it’s doable to construct environment friendly bridges, port mirrors, easy firewalls, community balancers and so forth.

The framework consists of the supply code of the PFQ kernel module, consumer-area libraries for C, C++11-14, Haskell language, an accelerated pcap library, an implementation of pfq-lang as eDSL for C++/Haskell, an experimental pfq-lang compiler and a set of diagnostic instruments.
