[100%) Question 3 The point-to-point link which is a part of a more complex network connects two hosts, H1 and H2, via two routers R1 and R2, as is shown in the Figure 3.1 below. Both hosts H1 and H2 use the IPv4 protocol. The packets are transmitted between H1 and H2 over the non-IPv4 links in frames with a 24-byte header. The link between the Host 1 and the router R1 has the MTU of 600 bytes (including the 24-byte frame header), the link R1 - R2 has the MTU of 512 bytes (including the 24-byte header), and the link between R2 and Host 2 has the MTU of 600 bytes (including the 24-byte header). The transport layer at the Host 1 passes to its IPv4 Network Layer a datagram which contains 1200 bytes of the data and 20 bytes of the TCP header for transmission to the Host 2. Calculate the sizes of all fragments for each link, (Host 1 - R1). (R1 - R2), and (R2 - Host 2), assuming that the network operates in a non- transparent fragmentation mode.
