Q1) The questions below are cumulative, that is, for each question assume the situation is as at the end of the preceding question. Assume that the MSS is 1000B and that the receiver always advertises a receive window size rwnd of 65535 bytes. Window scaling is not in use. Assume slow start is in use and the initial congestion window cwnd size is 1 MSS. Finally, assume the sender always has data to send and the network can handle 10000 bytes per RTT before losing data. Determine successive values of congestion window in bytes:

(1) up to the point where the network saturates (starts losing data).

(2) after the loss up to the point where the network again saturates.
