consider the udp header 12 03 00 0f 00 1e a3 10. what is the total length of the udp?


Expert Answer

Step 1

The User Datagram Protocol (UDP) is a transport layer communication protocol in the TCP/IP model.

The User Datagram Protocol (UDP) header is an 8-bytes simple and fixed header.

A UDP header has four-part and each part of 16 bit or 2-bytes.

The first part is Source port number and its size is 2 bytes

The second part is Destination port number and its size is 2 bytes

The third part is Total length, it is the length of UDP header and data, its size is 2 bytes. The minimum length is 8-bytes

The Fourth part is Checksum, it is 2 bytes one’s complement of the one’s complement sum of the UDP header.

If the value of checksum is zero, it means checksum is disabled.

Step 2

The given User Datagram Protocol header is 12 03 00 0F 00 1E A3 10.


The Source port number is 12 03.

The Destination port number is 00 0F.

The length is 00 1E.


The hexadecimal value of length is 00 1E

The ...
