  • UDP Packets are called as user datagram,
  • User Datagram have a fixed-size header of 8 bytes.
  • User Datagram Protocol (UDP) located between the application layer and the IP layer.
  • UDP serves as the intermediary between the application programs and the network operations.

Source port number: 
  • This is the port number used by the process running on the source host.
  • It is 16 bits long, value range from 0 to 65,535.
  • If the source host is the client, the most cases is an ephemeral port number, and the server port number in most cases is a well-known port number.

Destination port number:
This is port number used by the process running on the destination host.

This is a 16-bit field that defines the total length of the user datagram, header plus data.

This field is used to detect errors over the entire user datagram (header plus data).
