Also it has a "TCP-friendly" (actually a Reno-friendly) mode to make sure CWND growth is always bigger than Reno.

WebNov 8, 2024 · In the same way, there is a window size in the congestion control mechanism. It increases gradually. In the flow control, the window size (RWND) is sent with the TCP header. Although in congestion control, the sender node or the end device stores it. The sender starts sending packets with window size (CWND) of 1 MSS (Max Segment Size). The destination indicates the size of the receiver window through the TCP header. This advertises the amount of data that it can receive and enables the congestion window to determine the amount of data it can reliably transmit without an ACK. Once received, the data is stored in the receiver buffer and the … See more Network congestion occurs when packets sent from the source (the server) exceed what the destination can handle (the user).
