Consider sending a $1600-$byte datagram into a link that has an MTU $($Maximum transmission unit$)$ of $500$ bytes. Suppose the original datagram is stamped with the identification number $291\mathrm{.}1.$ Excluding the last fragment, what will be the size of the data for each fragment?bytes$2.$ How many fragments are generated?$($round your answer up to the next wholenumber$)3.$ What will be the size of the last datagram?bytes $($including IP header$).$
