Summary:
This paper proposes and evaluates performance of an on-demand packet capture process which depends on architectures with multiple CPU cores. Earlier research into multi-core capture focused on the nominal throughput, where packets are captured only to be counted, and found that even single-core capture is sufficient for 10Gbps environments. This paper argues that even simple processing logic incurs per-packet cost and invalidates this conclusion. On the other hand, the multi-core on-demand process presented in this paper can handle higher packet throughput and is sufficiently flexible to support even complex per-packet processing logic.
