$4.$ The diagram below shows the process of establishing a TCP connection and data transfer between Host A and Host $B.$ Fill in the correct sequence and acknowledgment numbers for $x1$ to X$9$ based on the TCP protocol rules. $(10$ points$)$

Scenario:

Host A initiates a connection with a SYN segment having an initial sequence number $($ISN$)$ of $110.$

Host B responds with a SYN$-$ACK segment.

Host A acknowledges with an ACK segment.

Host A then sends a data segment with a payload of $1000$ bytes.

Host B responds with an ACK and sends a data segment with a payload of $200$ bytes.

Host A acknowledges the received data segment from Host $B.$
