WebMay 8, 2024 · In the network transport area, congestion control is how to decide how much data the connection can send into the network. It has an important role in networking so as not to overrun the link but also at the same time it needs to play nice with other connections in the same network to ensure that the overall network, the Internet, doesn’t collapse. WebJul 24, 2013 · A congestion window ( cwnd) allows the sender to have at most cwnd unacknowledged bytes at any given time, effectively controlling the rate at which data is sent.

WebWe are informally measuring cwnd in units of full packets; strictly speaking, cwnd is measured in bytes and is incremented by the maximum TCP segment size. This strategy here is known as Additive Increase, Multiplicative Decrease, or AIMD; cwnd = cwnd +1 is the additive increase and cwnd = cwnd /2 is the multiplicative decrease. WebCongestion Control is a mechanism that controls the entry of data packets into the network, enabling a better use of a shared network infrastructure and avoiding congestive collapse.
