Question

Consider the client a sends the data of 12bytes to the sender B using the UDP. What is the efficiency of the transmission at the UDP level assuming no options in the UDP header

Answer 1

• In UDP protocol, the formula for computing at the UDP level assuming no options in the UDP header is

efficiency of the transmission = $\frac{Number of Bytes Transferred}{Number of Bytes Transferred + Length of UDP header}$

• UDP header is 8 bytes in length
• Data is 12 bytes
• Hence substituting $\frac{12}{12+8}$ = $\frac{12}{20}$ = 0.6
