On the other hand, congestion control is a mechanism used by a network to control congestion in the network. Congestion control prevents packet loss and delays due to network congestion. Congestion control can be seen as a mechanism for ensuring that an entire network can handle traffic arriving on the network. Related Posts. Difference between flow control and error control. Traffic Shaping and Policing — Difference. Difference between static and dynamic routing. For each connection, TCP maintains a congestion window, limiting the total number of unacknowledged packets that may be in transit end-to-end.
This is somewhat analogous to TCP's sliding window used for flow control. Flow control is important because it is possible for a sender to transmit information at a faster rate than the destination can receive and process it.
This can happen if the receiver has a heavy traffic load in comparison to the sender, or if the receiver has less processing power than the sender. Flow control mechanisms can be classified by whether or not the receiving node sends feedback to the sending node. Flow control is important because it is possible for a sending computer to transmit information at a faster rate than the destination computer can receive and process it.
Flow control is accomplished by the receiver sending back a window to the sender. The size of this window, called the receive window, tells the sender how much data to send. Often, when the client is saturated, it might not be able to send back a receive window to the sender to signal it to slow down transmission.
Furthermore, they are classified based on criteria like modifications need to be done on the current network and the fairness criterion used by the algorithm. What is the difference between Flow Control and Congestion Control? Although, Flow control and congestion control are two network traffic control mechanisms used in computer networks, they have their key differences. Flow control is an end to end mechanism that controls the traffic between a sender and a receiver, when a fast sender is transmitting data to a slow receiver.
On the other hand, congestion control is a mechanism that is used by a network to control congestion in the network. Congestion control prevents loss of packets and delay caused due to congestion in the network. Congestion control can be seen as a mechanism that makes sure that an entire network can handle the traffic that is coming to the network.
