Question 162Asked in DSSSB TGT Computer Science, 24 Jun 2023, Shift 3 (4:30 PM)Which of the following statements is true about slow start phase of the TCP congestion control?
- ACongestion window increases by 1 Maximum Segment Size every round trip time.
- BCongestion window approximately doubles every round trip time.
- CCongestion window increases by 2 Maximum Segment Size on every successful acknowledgement.
- DCongestion window approximately doubles on every successful acknowledgement.
Show answerHide answer
Correct answer: (B) Congestion window approximately doubles every round trip time.
Explanation
In slow start, cwnd grows by 1 MSS for each ACK, which roughly doubles the window every round-trip time until it reaches the threshold.
