$9.$ Consider nodes A and B are communicating over a TCP type of connection. Node A is transmitting a huge size of video to node B$,$ while node B is transmitting a long song to node A $.$ Current $($at the beginning of the scenario$)$ receive buffer sizes are $1500$ B $.$ and $2000$ B $.$ respectively for nodes A and B $($and this information is known by the other parties$).$

Fill the listed TCP header parameters $($ones not filled$)$ for the packets in the tables below.
