PFQ v6.2

Introduction

A functional framework designed for Linux operating system built for efficient packet capture/transmission (10G, 40G and beyond), in-kernel functional processing, kernel-bypass and packets steering across groups of sockets/end-points.

Features

• Data-path with full lock-free architecture.
• Preallocated pools of socket buffers.
• Compliant with a plethora of network devices drivers.
• Rx and Tx line-rate on 10-GBit links (14.8 Mpps), tested with Intel ixgbe vanilla drivers.
• Transmission with active timestamping.
• Groups of sockets which enable concurrent monitoring of multiple multi-threaded applications.
• Per-group packet steering through randomized hashing or deterministic classification.
• Per-group Berkeley and VLAN filters.
• User-space libraries for C, C++11-14 and Haskell language.
• Functional engine for in-kernel packet processing with pfq-lang.
• pfq-lang eDSL for C++11-14 and Haskell language.
• Accelerated pcap library for legacy applications.
