Question $5$

The IPv$4$ network connects two hosts $H1$ and $H2$ via three routers $R1,R2,$ and $R3,$ as is shown in the Figure $5\mathrm{.}1$ below. The link between the host $H1$ and the router $R1$ has the MTU of $1500$ bytes. The link R$1-$ R$2$ has the MTU of $576$ bytes. The link between the routers R$2$ and R$3$ has the MTU of $600$ bytes, and between R$3$ and H$2$ has the MTU of $1500$ bytes. The host H$1$ generates TCP$/$IP packet which contains $1460$ bytes of the application data for a reliable transmission to the host H$2.$ The packet Identification is $230.$ Calculate the sizes of all fragments and show the values of the Identification, Total Length, M$-$bit, D$-$bit, and Fragment Offset for all fragments in each link. Assume that the network operates in a non$-$transparent fragmentation mode.
