Question

In slow start, a sender doubles its window size every RTT if all sent packets were acknowledged.

IT IS GIVEN AS TRUE BUT WHAT IF THE THRESHOLD OCCURS  THEN IT WILL NOT DOUBLE  OR SAY ON DOING DOUBLE IT IS CROSSING THE THRESHOLD LIMIT THEN IT INCREASES ACCORDINGLY ..SO I THINK IT SHOULD BE FASE ?????

Answer 1

1-In case of slow start in every RTT window size becomes double or we can say for each acknowledgement window size increases by  1 MSS(maximum segment size). In slow start phase window size increases exponentially.

2-when it reaches threshold slow start  phase ends up ,so after that congestion avoidance phase will start so for every RTT window size increases by 1 MSS.

so the given statement is true.(As question has been asked in slow start phase)
