Last year Intel announced a new family of 100 Gigabit network adapters, code-name Columbiaville. These new adapters, based on the new Intel Ethernet Controller E810, support 10/25/50/100 Gbps link speeds and provide programmable offload capabilities. Programmability 800 Series adapters implement new features to improve connectivity, storage protocols, and programmability, also thanks to the Dynamic Device […]
Introducing PF_RING Configuration Wizard
Getting started with PF_RING can be a bit tricky as it requires the creation of a few configuration files in order to setup the service, especially when ZC drivers need to be used. First of all it requires packages installation: PF_RING comes with a set of packages for installing the userspace libraries (pfring), the kernel […]
Introducing PF_RING 7.4: PF_RING FT, Containers and Virtual Functions Support
This is to announce a new PF_RING major release 7.4. This release includes many improvements to the PF_RING FT library, which is now more mature thanks to new API functionalities and features that provide more flexibility. This release also addresses many issues, and moves a step forward in the same direction of release 7.2, which included […]
How to accelerate Bro with PF_RING FT
We discussed many times about the large quantity of work IDSs have to carry on, and the high CPU load they require, this is the case of Suricata due to the thousands of rules that need to be evaluated for every single packet, but this is also the case of the Bro Network Security Monitor. […]
How to accelerate Suricata, Bro, Snort with PF_RING FT
In a previous post we discussed the advantages of using specialized adapters featuring flow offload in hardware for accelerating IDS applications. What we have learnt is that IDSs are typically CPU-bound applications, and this is mainly caused by the thousands of rules that need to be evaluated for every single packet (of course in addition to packet capture). […]
Introducing nBroker: Traffic Steering and Filtering on Intel RRC (FM10K)
Exactly two years ago we introduced Intel FM10K (FM10000) support in PF_RING ZC. The Intel FM10K ethernet controller family supports 10/25/40/100 Gbit on the same NIC, at a convenient price (sub 1000$ range) and it powers NIC various models manufactured by Silicom Inc. The most interesting aspect of the FM10K is the programmability that this adapter provides. […]
Introducing PF_RING FT: nDPI-based Flow Classification and Filtering for PF_RING and DPDK
Motivation Most network monitoring and security applications are based on flow processing, which is in practice the activity of grouping packets based on common attributes (e.g. source and destination IP, source and destination port, protocol, etc.) and do some analysis based on the collected information. What happens behind the scenes can be divided in a few major […]
Introducing PF_RING 7.0 with Hardware Flow Offload
This is to announce a new PF_RING major release 7.0. In addition to many improvements to the capture modules, drivers upgrades, containers isolation, the main change of this release is the ability to offload flow processing to the network card (when supported by the underlying hw). Flow offload is a great feature for cutting the […]
PF_RING 6.6 Just Released
After almost one year of development, this is to announce the release of PF_RING 6.6. In this release we have worked on different areas: Introduced nBPF, a software packet-filtering component similar to BPF, that is able to exploit hardware packet filtering capabilities of modern network adapters and transparently deliver these facilities to user-space applications such […]
Capture, Filter, Extract Traffic using Wireshark and PF_RING
Last year we introduced our new nBPF library able to: 1. Convert a BPF filter to hardware rules for offloading traffic filtering to the network card, making it possible to analyse traffic at 100G. 2. Accelerate traffic extraction from an indexed dump set produced by n2disk, our traffic recording application able to produce multiple PCAP […]
