DPKT

Optimized for performance when dissecting packets from pcap files, as highlighted in the key features, enabling efficient network traffic analysis.

Enables programmatic construction of network packets for testing or simulation, making it easy to generate custom traffic without deep protocol knowledge.

Includes built-in definitions for fundamental protocols like Ethernet, IP, TCP, UDP, and ICMP, reducing the need for manual implementation in Python.

Offers an intuitive interface that integrates seamlessly with Python workflows, as noted in its design philosophy for straightforward packet manipulation.
