6. Figure 1 shows an example variation of congestion window for TCP Reno. Assume that TCP segment size is 1500 bytes and average RTT is 150 msec. i) What is the average throughput (in bits/sec) during transmission rounds starting from round 6 until round 10 starts. ii) What are the values of ssthresh at the 18th and 24th transmission rounds? iii) Suppose TCP Tahoe is used (instead of TCP Reno), and there is a timeout event at 22nd round. How many segments have been sent out from 17th round till 22nd round, inclusive? Congestion window size (segments) 0 0 2 4 6 8 10 12 14 16 18 20 22 24 26 Transmission round
