About UDP

UDP is a minimal transport protocol with no built-in connection state or retransmission logic. It is commonly used where low overhead and fast delivery are preferred over guaranteed reliability.

UDP Header Structure

Source Port (2 bytes): sender application port.
Destination Port (2 bytes): receiver application port.
Length (2 bytes): UDP header plus payload size.
Checksum (2 bytes): datagram integrity check.

Why Decode UDP Packets

Decode UDP datagram headers from hex for source/destination ports, length, and checksum.
