PF_RING FT - [Linux]

PF_RING FT license (per system) for any adapter PF_RING/pcap/DPDK. It includes 5 days installation support and one year of updates

High-speed packet capture, filtering and analysis.

PF_RING™ is a new type of network socket that dramatically improves the packet capture speed, and that’s characterized by the following properties:

1. Available for Linux kernels 2.6.32 and newer.
2. No need to patch the kernel: just load the kernel module.
3. 10 Gbit Hardware Packet Filtering using commodity network adapters
4.  User-space ZC (new generation DNA, Direct NIC Access) drivers for extreme packet capture/transmission speed as the NIC NPU (Network Process Unit) is pushing/getting packets to/from userland without any kernel intervention. Using the 10Gbit ZC driver you can send/received at wire-speed at any packet sizes.
5.  PF_RING ZC library for distributing packets in zero-copy across threads, applications, Virtual Machines.
6. Device driver independent.
7.  Support of Accolade, Exablaze, Endace, Fiberblaze, Inveatech, Mellanox, Myricom/CSPI, Napatech, Netcope and Intel (ZC) network adapters.
8. Kernel-based packet capture and sampling.
9. Libpcap support (see below) for seamless integration with existing pcap-based applications.
10. Ability to specify hundred of header filters in addition to BPF.
11. Content inspection, so that only packets matching the payload filter are passed.
12. PF_RING™ plugins for advanced packet parsing and content filtering.

Vanilla PF_RING™

PF_RING™ is polling packets from NICs by means of Linux NAPI. This means that NAPI copies packets from the NIC to the PF_RING™ circular buffer, and then the userland application reads packets from ring. In this scenario, there are two pollers, both the application and NAPI and this results in CPU cycles used for this polling; the advantage is that PF_RING™ can distribute incoming packets to multiple rings (hence multiple applications) simultaneously.

PF_RING™ Modules

PF_RING™ has a modular architecture that makes it possible to use additional components other than the standard PF_RING™ kernel module. Currently, the set of additional modules includes:

• ZC module.
  Have a look at the ZC page for additional information.
• FPGA-based card modules.
  Those modules add support for many vendors including Accolade, Exablaze, Endace, Fiberblaze, Inveatech, Mellanox, Myricom/CSPI, Napatech, Netcope.
• Stack module.
  This module can be used to inject packets to the linux network stack.
• Timeline module.
  This module can be used to seamlessly extract traffic from a n2disk dump set using the PF_RING™ API.
• Sysdig module.
  This module captures system events using the sysdig kernel module.
