$(20$ pts$)$ Reliable transport protocol rdt$3\mathrm{.}0$ is a stop$-$and$-$wait protocol that sends one

data packet and waits for a positive response before sending the next data packet. It uses

sequence numbers $0$ and $1.$ It can cope with corrupted packets and lost packets. It uses a timer

and retransmits a packet if it has not received the appropriate ACK before the timer times out.

When the sender in rdt$3\mathrm{.}0$ receives an ACK packet that is corrupt or has the wrong

sequence number, it ignores that packet. Suppose instead that the sender in $rdt3\mathrm{.}0$ retransmitted

the current data packet. Would this revised rdt$3\mathrm{.}0$ still work? Explain your answer considering

corrupt ACKs, ACKs with wrong sequence numbers, and lost data or ACK packets. $($You can

assume that no delayed ACKs arrive after the timer has expired.$)$
