A station A will have to transfer a message to another station B. The size of the message received by the IP entity is 7200 bytes. The IP datagram is identified with 0000H. The) datagram (s) carrying the message will have to cross 2 networks (RES1, RES2) Each network is configured with a specific MTU (for example, the RES1 MTU is 1200 bytes: MTU is the acronym for Maximum Transmission Unit, which defines the maximum size that the network frame can carry, i.e. the maximum size of the IP datagram). The MTU of the network RES2 is 900 bytes.

a)For each network, give the number of IP datagrams needed to carry the message in cases where the datagram is fragmented, give the value of the fields following of each fragment: fragment offset (fragment offset) and bit (More bit).
