IPv4 has the provision for fragmenting and reassembling packets. Consider the network in the figure below, where the MTUs of the link layers for the three IP hops is listed. These MTUs include the header of the packets. You can consider the IP packets to have no options, with a fixed header size of 20 bytes. a. Suppose you send a packet with a payload of 1400 bytes on this network. Fill in the table below listing all the fragments that are transmitted along each link. The fields in the table (other than the ’Link’ field), correspond to the values in the IP header, and we already filled in the first packet for you. (Recall that the Fragment Offset is represented as number of 8-byte increments. b. In the example above, where are fragments reassembled? Can they be reassembled anywhere else? Why or why not?
