About:
DAQ (Data Acquisition) is a library that provides a flexible framework for packet I/O and decoding. It serves as a pluggable interface for network intrusion detection systems like Snort, allowing them to decouple from the underlying hardware or software data source. This enables high-performance, hardware-accelerated packet capture and processing capabilities.
Key Features:
  • Pluggable architecture for modular packet acquisition
  • Supports multiple interfaces including AF_PACKET, PCAP, and NetFlow
  • Provides a unified API for packet I/O operations
  • Enables hardware acceleration and zero-copy packet processing
Use Cases:
  • Building high-performance network intrusion detection systems (NIDS)
  • Creating custom packet capture and analysis tools
  • Implementing network monitoring with hardware-specific optimizations
Alternatives:
  • libpcap – DAQ provides a more flexible, modular framework while libpcap offers standard packet capture functionality
