If someone could help me as soon as possible with this question on TCP

5. TCP Congestion Control (20 points) Please compute the maximum window size in segments that the following TCP connection can reach. We consider a single TCP (Reno) connection that uses 20Mbps link which does not buffer any data. Suppose the link is the only congested link between the TCP sender and receiver. The receiver's receive buffer is much larger than the congestion window. Each TCP segment size is 1500 bytes. The round-trip time (RTT) between the sender and the receiver using the connection is 150 msec (mili-second). Assume that the TCP connection is always in congestion avoidance phase. (Proof is needed)
