On a TCP connection, current congestion window size is Congestion Window = 4 KB. The window size advertised by the receiver is Advertise Window = 6 KB. The last byte sent by the sender is LastByteSent = 10240 and the last byte acknowledged by the receiver is LastByteAcked = 8192. The current window size at the sender is

Explanation:
Detailed explanation-1: -1 Answer. The time taken (in msec) by the TCP connection to get back to 32 KB congestion window is 1100 ms.
Detailed explanation-2: -Congestion Window It is usually referred to in multiples of maximum segment size (MSS). So an MSS of 1460 and a cwnd of 33 would be 48k bytes. The cwnd at the beginning of a connection is usually 2, 3, or 10 depending on the operating system and kernel version. The cwnd is initially increased by TCP Slow Start.
