Student Initials: 24. [8 marks] An Internet user would like to transfer a message from his computer (host A) to another computer (host B). The size of the message passed to the IP layer is 2400 bytes. NET2 MTU 640 NET3 MTU= 1 500 NET1 R1 R2 MTU 1500 The datagram(s) carrying the message will have to cross two routers (R1 and R2) and 3 networks (NET1, NET2, and NET3) as described in the above figure. Each of these networks has a specific MTU (for example the MTU of network 1 is 1500 bytes. MTU here stands for Maximum Transmission Unit, the largest data that a frame can carry.). a) Give the number of the IP datagram(s) needed, and the total length of each IP datagram at each For the cases where the datagram is fragmented, give the value of the fragment Offset field and the value of the More bit in the Flags field of each fragment. b)
