摘要
This paper presents two approaches to parallelizing the Snort network intrusion detection system (NIDS). One scheme parallelizes NIDS processing conservatively across independent network flows, while the other optimistically achieves intra-flow parallelism by exploiting the observation that certain intra-flow dependences are uncommon and may be ignored under certain circumstances. Both schemes achieve average speedup over 2 on four cores, with an average throughput over 1 Gbps on 5 traces tested.
