What will the congestion window size after 4 RTTs be provided the congestion window is assigned to 1 MSS(=512B) initially?
My approach:
First transmission: 1 MSS=512 B are sent, after first ack is received window size is 2MSS=1024 B, next after next two acks are received window size is 4 MSS, finally after the receival of 4 more acks window size is 8MSS=4096 B.
Ans given is 2560 B . Please correct me if I am wrong.
