Question

Consider sending a 2400-byte datagram into a link that has an MTU of 700 bytes. Suppose the original datagram is stamped with the identification number 422. How many fragments are generated

Answer 1

4

Step-by-step explanation:

Given the following data

Datagram = 2400 bytes

The minimum length of an IP header = 20

Maximum Transmission Unit - MTU = 700

The original datagram is stamped with the identification number = 422

Formula = The required number of fragments = ( Datagram - IP Header) ÷ (MTU - IP Header)

= (2400 - 20) ÷ (700 - 20)

= 2380 ÷ 680

= 3.5 ≈ 4

Hence, in this case, the correct number of fragment generated is 4.
