In TCP connection, congestion occurs if the load
on the network is greater than the capacity of
the network. TCP uses the following algorithm to
handle congestion. The algorithm is based on
the size of the congestion window (cwnd) which
starts with one maximum segment size (MSS).
The MSS is determined during connection
establishment. At each time the whole window
of segments is acknowledged (one
transmission), the size of the window grows
exponentially. To stop this exponential growth,
the sender keeps the track of a threshold. The
threshold is set to 16 MSS. After reaching the
threshold, the size of the congestion window is
increased by 1. After how many transmissions
the congestion window size will be 22 MSS?
