Ok, but how much time do I have?
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 main point. A common misconception on this field is that hardware-accelerated cards will do the magic and solve all problems. This is a wrong statement. Technologies such as PF_RING, DNA, and those cards reduce the …
