Consider the following statements regarding the slow start phase of the TCP congestion control algorithm. Note that cwnd stands for the TCP congestion window and MSS denotes the Maximum Segment Size.The cwnd increase by 2 MSS on every successful acknowledgement. The cwnd approximately doubles on every successful acknowledgedment. The cwnd increase by 1 MSS every round trip time. The cwnd approximately doubles every round trip time. Which one of the following is correct

Explanation:
Detailed explanation-1: -During congestion control, CWND is increased by the number of segments acknowledged each time an ACK is received. This is exponential growth, rather than the slower linear growth of AIMD during the congestion avoidance phase.
