Question

Let the size of congestion window of a TCP connection be 32 KB when a timeout occurs. The round trip time of the connection is 100 msec and the maximum segments size used is 2 KB. The time taken (in msec) by the TCP connection to get back to 32 KB congestion window is

Answer 1

Congestion window =32 KB.
Threshold = 16 KB
$2\to 4\to 8\to 16\to 18\to 20\to 22\to 24\to 26\to 28\to 30\to 32$
Time taken to reach 32 KB = 12 segments$\times$100 msec =1200 msec.
