Question $5$

The IPv$4$ network connects two hosts $H1$ and $H2$ via three routers R$1,$ R$2,$ and R$3,$ as

is shown in the Figure $5\mathrm{.}1$ below. The link between the host $H1$ and the router R$1$ 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 $H2.$ 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.$|$
