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
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
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
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
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
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
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
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 … Continue reading
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 … Continue reading
