PFQ is a capturing engine designed for the Linux kernel that allows efficient packet capturing, in-kernel aggregation, functional processing and packet steering across sockets.
PFQ is highly optimized for multi-core architecture, as well as for network devices supporting multiple hardware queues. It works with any device driver (the ones shipped with the Linux Kernel) and provides a script (pfq-omatic) that patches and compiles source codes on-the-fly to obtain accelerated drivers.
The package provides the source code of the PFQ kernel module, user-space libraries for C, C++11 and Haskell languages and a set of diagnostic tools.
- 10-Gbit Line-rate (14,8Mpps) with Intel ixgbe vanilla driver.
- Socket groups allow for concurrent monitoring of multi-threaded applications.
- Per-group packet steering through randomized hashing algorithms or deterministic packet classifications.
- Per-group Berkeley filters and per-group VLAN filters.
- Extensible framework for in-kernel functional monitoring (continuation passing style).
- User-space native bindings for C, C++11 and Haskell languages.
- PFQ-omatic, a script that allows to compile drivers and get the accelerated versions.
- Accelerated pcap library.
