Using Hardware Timestamps with PF_RING
Up to some years ago, hardware timestamps were available only on costly FPGA-based NICs. Slowly, NIC manufactures started to consider hw timestamps as an important feature, and they started to introduce them…

PF_RING and transparent_mode
Many PF_RING users know that for avoid patching the Linux kernel, as of PF_RING 4.x packets are received though NAPI. This means that the packet journey is the same used in standard…
Using PF_RING with Snort and Suricata for IDS/IPS Acceleration
Some users are exploiting PF_RING acceleration to improve popular IDS/IPS applications such as Snort and Suricata. Suricata leveraged PF_RING since day one thanks to Will Metcalf, whereas I have added (again together…
Meet ntop at RIPE 61 Rome (15-19 November)
Those who are interested in hearing about high-speed packet capture and filtering and to monitoring in general, can show up at the next RIPE 61 meeting that till take place in Rome…
Improving snort performance using PF_RING and multi-queue adapters
As of PF_RING 4.5.x, the user-space tools part of PF_RING have been enhanced with native snort support. As of version 2.9, snort sits on top of a library called DAQ (Data Acquisition…
10 Gbit Hardware Packet Filtering Using Commodity Network Adapters
The promise of filtering packets in hardware is not new. Unfortunately filtering network adapters are pretty expensive, not to mention if they run at 10 Gbit. Furthermore many commercial FPGA-based NICs feature…
PF_RING/TNAPI-based 10 Gbit Network Monitoring on Multicore Systems
Over the past couple of years, PF_RING has been enhanced to exploit innovations in computer hardware. In particular the availability of multicore systems and efficient controllers such as those introduced by Intel…
Modern Packet Capture and Analysis: Multi-Core, Multi-Gigabit, and Beyond
Sometimes people ask me a tutorial about PF_RING. Last year I have given a tutorial about it at the IM 2009 conference. I think that everyone interested in using PF_RING for going…
Installation Guide For PF_RING
Below you can find an installation guide for PF_RING written by Gunjan Bansal. The original blog entry can be found at this URL. ------------- Hi, This is my first guide so please…
10 Gbit PF_RING-based Hardware Packet Filtering and Balancing Previewed at the Intel Europe Conference
Intel Research Europe Conference, Bruxelles, May 4th 2010 Luca Deri and Joseph Gasparakis, senior Intel engineer, have previewed a new PF_RING-based technology they have co-developed that allows Linux users to fully exploit…
PF_RING and Transparent Mode
PF_RING has been designed for enhancing packet capture performance. This means that the RX path must be accelerated, and in particular a way to accelerate this is by reducing the journey of…
Introducing PF_RING DNA (Direct NIC Access)
This is to announce the availability of PF_RING DNA (Direct NIC Access) that significantly increments performance (up to 80%) when compared with Linux packet capture and PF_RING (non DNA). PF_RING is polling…
