What Does Tcp Do If The Sending Source Detects Network Congestion On The Path To The Destination??

TCP detects network congestion by looking for a decrease in the end–to–end throughput. If the sending source detects network congestion on the path to the destination, it will reduce its transmission rate to help alleviate the congestion. This is done by reducing the window size, increasing timeouts and retransmission values, and optionally backing off the sending rate.
