PF_RING ZC is ntop’s high-speed zero-copy technology for high speed packet capture and processing. Until now ZC supported 10/40/100 Gbit adapters from Intel based on ASIC chips, in addition to the FPGA-based 100 Gbit adapters already supported by PF_RING including Accolade/Napatech/Silicom. … Continue reading
Introducing PF_RING 8.0: Batch Packet Processing and XDP Support
This is to announce a new PF_RING release 8.0. This new stable version includes enhancements for improving application performances, by adding support for batch processing also in the standard API (it was already available in the ZC API), and consolidates … Continue reading
How to Dump, Index, and Layer-7 Filter Network Traffic at High Speed
n2disk is an application that many of the ntop community uses to dump traffic up to 100 Gbit. What few people know is that n2disk can index data not just using packet header information (i.e. IP, port. VLAN, MAC…) but … Continue reading
Introducing PF_RING ZC support for Intel E810-based 100G adapters
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 … Continue reading
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: … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
