The transmission control protocol (TCP) congestion control is highly significant to solve the issues related with network congestion during the sending or receiving of large number of packets. During the network congestion, it gets difficult for the network to handle maximum traffic which results in the degradation of QoS or quality of service. In order to neglect congestion of the network, TCP utilizes a congestion window along with the congestion policy. there is another instance where if the network fails to deliver the data with faster speed then it notifies the sender to slow down The packets.
