Slow-start begins initially with a congestion window size (cwnd) of 1, 2, 4 or 10 MSS. The value of the Congestion Window will be increased by one with each acknowledgement (ACK) received, effectively doubling the window size each round-trip time (approximately exponential). The cwnd increase by 1 MSS on every successful acknowledgement. Therefore, only statement (iv) is correct. Option (C) is true.

Consider the following statements regarding the slow start phase of th...
The correct answer is option 'C' - Only (iv) is true.
Explanation:
The slow start phase is an initial phase of the TCP congestion control algorithm, where the congestion window (cwnd) increases exponentially to quickly probe the network capacity. The goal is to find the optimal transmission rate without causing congestion. During this phase, the cwnd is increased by 1 MSS (Maximum Segment Size) for every round trip time (RTT).
Let's analyze each statement to determine its validity:
(i) The cwnd increases by 2 MSS on every successful acknowledgement.
This statement is incorrect because during the slow start phase, the cwnd increases by 1 MSS, not 2 MSS, for every successful acknowledgement.
(ii) The cwnd approximately doubles on every successful acknowledgement.
This statement is incorrect because the cwnd does not double on every successful acknowledgement during the slow start phase. It only increases by 1 MSS for every successful acknowledgement.
(iii) The cwnd increases by 1 MSS every round trip time.
This statement is correct. During the slow start phase, the cwnd is increased by 1 MSS for every round trip time. This helps in gradually probing the network capacity and avoiding congestion.
(iv) The cwnd approximately doubles every round trip time.
This statement is correct. The cwnd approximately doubles every round trip time during the slow start phase. This exponential increase helps in quickly finding the optimal transmission rate.
In conclusion, only statement (iv) is true. The slow start phase of the TCP congestion control algorithm increases the cwnd by 1 MSS for every round trip time and approximately doubles the cwnd every round trip time.
