This is to announce the availability of PF_RING DNA (Direct NIC Access) that significantly increments performance (up to 80%) when compared with Linux packet capture and PF_RING (non DNA). 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 …

Suricata is the next generation open source IDS/IPS developed byt the Open Information Security Foundation. It is a pleasure to announce that ntop has joined the core development team as the Linux version of Suricata is based on acceleration provided by PF_RING. In the near future PF_RING will be extended so that it can also accelerate packet transmission in order to move the Suricata IPS performance to the next level. More information can be found here. …
