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…

Precise Interface Merging Without Hardware Timestamps

In network monitoring it is very common to use taps for duplicating network traffic (RX and TX directions). Taps are important as they allow network probes to operate passively without interfering with…

DNA vs netmap

In the past months I have received a few emails about how to position DNA with respect to netmap. To many people they look like two competing solutions, but in reality they…

PF_RING in 2012

From time to time the kernel folks are sick and tired of people saying PF_RING is better than what we have upstream, it really isn't. Fortunately (for PF_RING) the story is a…

Inline Snort Multiprocessing with PF_RING

Dear all, our friends at MetaFlows have tested snort on top of PF_RING DAQ using 6765 Emerging Threats Pro rules. Using PF_RING-aware drivers (that are not optimized at all for TX), they…

Not All Servers Are Alike (With DNA)

PF_RING DNA is a great success for us as we see the users community grow every day. At the same time, sometimes we receive complains of people who say that they can't…

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…
