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
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 … Continue reading
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 … Continue reading
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 … Continue reading
Positioning PF_RING ZC vs DPDK
Last week I have met some PF_RING ZC and DPDK users. The idea was to ask questions on PF_RING (for the existing ZC users) and understand (for DPDK users) whether it was a good idea to jump on ZC for … Continue reading
See You Next Week at the ntop Users Meeting
This is to renew the invitation to meet you next week at the ntop users meeting colocated with Sharkfest Europe. The event is free of charge but seats are limited. More information can be found here. Hope too see you … Continue reading
Introducing nBPF: line-rate hardware packet filtering (yes Wireshark at 100G is possible)
Modern network adapters such as Exablaze, Napatech and Silicom’s Intel FM10K, support hardware filters. Unfortunately every company has its own way to set filters, no unified API, and no support of any BPF-like filters. Most of the network monitoring community … Continue reading
PF_RING 6.4 Just Released
This is to announce the release of PF_RING 6.4 that contains various improvements, new network adapters supported in ZC mode (including Intel 100 Gbit), and bug fixes. Developers can access the documentation for the PF_RING 6.4 API in Doxygen format. Changelog … Continue reading
