Accelerating Snort with PF_RING DNA
Since some time, PF_RING includes a DAQ (Data AcQuisition library) module for the popular Snort IDS/IPS. With respect to Linux AF_PACKET, the use of PF_RING significantly accelerates all snort operations. We have…

Using PF_RING DAQ for high-performance 1/10 Gbit Snort-based IDS/IPS
Months ago we have started to design a new PF_RING DAQ module for snort. We decided to do this project with ENEO Tecnologia who has both sponsored the development and helped us…
PF_RING DNA/Libzero vs Intel DPDK
From time to time, we receive inquiries asking us to position PF_RING (DNA and Libzero) against Intel DPDK (Data Plane Development Kit). As we have no access to DPDK, all we can…
Hardware-based Symmetric Flow Balancing in DNA
Years ago, Microsoft defined RSS (Receive-Side Scaling) with the goal of improving packet processing by enabling multiple cores to process packets concurrently. Today RSS is implemented in modern 1-10 Gbit network adapters…
Say hello to Libzero
Last year we have introduced PF_RING DNA for implementing 0% CPU receive/transmission on commodity 1/10 Gbit network adapters. We considered DNA as a starting point, as it implemented high-speed RX/TX that was…
PF_RING DNA RFC 2544 Benchmark
Over the past couple of weeks we have further improved the DNA performance, and thus we have decided to test its performance. In order to do reproducible measurements we decided to adopt…
Benchmarking PF_RING DNA
For years networking companies have used the buzzword zero-copy to qualify those hardware/software solutions that allow applications to play with packets without the need to copy them at all. Zero-copy needs DMA…
PF_RING 5.0 Introduced: DNA 1/10 Gbit and vPF_RING
We've just cut the code of PF_RING 5.0. As it contains many changes with respect to the previous version, it deserved a major version number. We refreshed our DNA drivers to 1…
