PFQ v4.0 
========

Introduction
------------

PFQ is a networking framework designed for the Linux operating system 
that allows efficient packet capture/transmission, in-kernel functional processing 
and packet steering across sockets. 

PFQ is highly optimized for multi-core architecture, as well as for network 
devices equipped with multiple hardware queues. It works with any device
driver and provides a script designed to obtain accelerated versions of the drivers 
from their source codes.

The framework enables the development of high-performance networking applications 
with different languages (i.e. C, C++ and Haskell). In addition, a pure functional language 
designed for software defined monitoring and networking is included: PFQ/lang.

The package provides the source code of the PFQ kernel module, user-space libraries 
for C, C++11 and Haskell languages, PFQ/lang implemented as eDSL and a set of diagnostic tools.

Features
--------

* Preallocated pools of socket buffers.
* Compliant with a plethora of network devices drivers.
* Rx and Tx 10-Gbit line-rate (14,8Mpps), on-top-of Intel ixgbe vanilla drivers.
* Transparent support of kernel threads for asynchronous packets transmission.
* Concurrent monitoring of multiple multi-threaded applications by means of groups of sockets.
* Per-group packet steering through randomized hashing or deterministic classification.
* Per-group Berkeley and VLAN filters.
* Functional engine for in-kernel packet processing with **PFQ/lang**.
* User-space libraries for C, C++11-14 and Haskell languages.
* PFQ/lang eDLS for C++11-14 and Haskell language.
* Accelerated pcap library (line-speed tested with captop).
* **pfqd** daemon used to parallelize multiple instances of pcap legacy applications.
* **pfq-omatic**, a script designed to accelerate vanilla drivers.
* I/O user<->kernel shared-memory on top of **HugePages**.
