IP packet capture on high throughput networks by using NUMA architectures

Capture packets from IP networks is a commonly used technique in many IT fields for monitoring and analysis the IP traffic flows exchanged over computer networks. The new infrastructures for high throughput networks, however, have made this important technique more and more complex to carry out (also in small or medium sized local networks) even if using the newest multi-core systems developed today. This paper therefore shows some limits of a recent packet capture system, implemented by using a NUMA architecture, and suggests a possible solution that could be adopted to obtain a full functional IP packet capture system on high throughput networks.
