PF_RING

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…

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 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…

Low RX/TX Latency with DNA

One of the great consequences of the DNA design, is that user-space applications can now transmit and receive packets without going through the kernel TCP/IP stack at all. This can be profitably…
