Accelerating packet capture and processing is a constant race. New hardware innovations, modern computing architectures, and improvements in packet capture (e.g. PF_RING) allow applications to reduce the (both CPU and real) time they need for processing packets. But the main question still holds: how much time do I have for processing packets? This is the […]

10 Gbit PF_RING DNA on Virtual Machines (VMware and KVM)

As virtualization is becoming pervasive in data-centers, you might wonder whether you can benefit of DNA on virtualized environments. The answer is positive. This post explains you how to use DNA on both […]

Today we released PF_RING 4.7.0. It includes 10 Gbit DNA support (RX/TX) for Intel-based 82598/99 ethernet adapters thus you can finally manipulate packets at wire-rate using commodity adapters. With a low-end Core2Duo you can handle more than 11 Mpps per queue, with a Xeon you can have wire rate at any packet size and using limited […]
