In a TCP Connection, let station A sends a SYN segment with Initial sequence mumber $300$ to Station B$.$ Station B acknowledges the SYN segment with its sequence number $3000$ and rwnd: $1000.$ Then station A acknowledged with rwnd: $2000.$ Further data communication begins from Station A for $8$ segments of $200$ MSS each. Sketch the sequence of segment exchanges including parameter values in the segment headers, and state as a function of time at the two stations under the following situations: $10211.$ If $3$rd segment is acknowledged but unprocessed by Station B $2.$ If $4$th segment is lost $3.$ If acknowledgement for $5$th segment is lost
