RTT = 10 msec
CWS = 36 KB
Threshold = 18 KB
After 8 transmission, a time-out occurs.
After time out, time taken to send first full window of 18 KB?
Initially window size = 2KB
1st = 2KB
2nd = 4KB
3rd = 8KB
4th = 16KB ( threshold reached, start Congestion avoidance phase)
5th = 18KB
6th = 20KB
7th = 22KB
8th = 24KB
__ Time Out Occurs, Threshold is set to half of the
current window, i.e. 12KB, and start with slow start phase.
9th = 2KB - 1
10th = 4KB - 2
11th = 8KB - 3
12th = 12KB- 4
13th = 14KB- 5
14th = 16KB- 6
15th = 18KB
After time out, after 6 transmission (60 ms) we can send full winddow of size 18 KB.
But, time taken to send first full window of size 18KB will be 60ms + 10 ms = 70ms.
