Hardware support for real-time network security and packet classification using field programmable gate arrays
Deep packet inspection and packet classification are the most computationally expensive operations in a Network Intrusion Detection (NID) system. Deep packet inspection involves content matching where the payload of the incoming packets is matched against a set of signatures in the database. Packet …

Congestion on the Internet : operator responses, economic analysis, and improving the network architecture
… document how providers are engaged in not just deep packet inspection, but deep flow inspection - tracking, shaping, and actively managing the state of individual flows. We explain why network operators attempt to manage traffic in these manners by looking at both the technical and economic …

Off-chip Communications Architectures For High Throughput Network Processors
… as a result of higher line rates, an increase in deep packet inspection operations and an unstoppable expansion in lookup tables. As line-rate data and NPU processing power increase, memory access time becomes the main system bottleneck during data store/retrieve operations. The growing demand for …

Detecting advanced botnets in enterprise networks
… problem introduced by encrypted botnets is that Deep Packet Inspection (DPI)-based security systems are foiled. We measure the effects of encryption on three security systems, including Snort, Suricata and BotHunter (BH) using the encrypted botnet traffic generated by BotTalker. The results show …
