?PLEASE HELP ME WITH TCP TRANSMISSION PROBLEM.

3. (21 pts: 5 for a, 2 each for b-i) We are using TCP Reno. ssthresh is set to 16. Assume no errors a. (5 pts) Starting from a window size of 1, calculate how many round you need to send 30 packets, as the window size (cwnd) grows each round. Subtract that from your remaining total to show how many packets remain in the last column Round # Packets Sent Packets Remaining 4 b. If you had 30 packets to send instead of 31, would anything change? Assume a packet is determined to be lost when cwnd-32 and ssthresh-16. Will ssthresh be changed? To what value? c. d. If you are in slow start, will cwnd pass through each integer value? In other words when we move in one round from cwnd-8 packets to the next round when cwnd-16, will cwnd jump to 16 or will it grow one by one? Why? When TCP sends an entire window's worth of many packets at a time, how many RTT's (round-trip times) is that considered to take? e. For the next questions, assume MSS is 1000 bytes, cwnd is 10,000 bytes f. How many packets can be sent in one window's worth of transmissions? g. When you are in slow start, and you receive an ACK, how much does cwnd grow? h. When you are in congestion avoidance, and you receive an ACK, by how much does each ACK cause the value of cwnd to increase? Assume MSS-1000 bytes cwnd-10,000 bytes, and show the equation and result
