An Approach for Unifying Rule Based Deep Packet Inspection

High performance Internet traffic inspection and layer-7 content analysis have become essential functions of high speed networks. Over the past decade several DPI systems have evolved targeting specific issues related to traffic management, user/application policing, intrusion detection/prevention, URL/malicious/unwanted content filtering. Snort, OpenDPI, Bro, L7-filter, ClamAV are a number of open-source tools based on custom DPI engines and custom rule-sets. The surging demand for higher bandwidth DPI systems capable of supporting larger rule-sets requires the use of hardware acceleration and hardware-based systems.
