TCP - difference between Congestion window and Receive window

Network congestion occurs when packets sent from the source (the server) exceed what the destination can handle (the user). When the buffers get filled up at the destination, the packets are temporarily stored in buffers at both the source and destination as they wait to be forwarded to the upper layers. This … See more The destination indicates the size of the receiver window through the TCP header.
