Tcp flow control receive side of tcp connection has a receive buffer. Flow control tcp uses sliding window to handle flow control the size of the window is determined by the lesser of two values. Tcp flow control and error control flow control flow control regulates the amount of data a source. The client and the server can then request and reply message by write and recalls. Tcp is the protocol that guarantees we can have a reliable communication channel over an unreliable network. Difference between flow control and congestion control. At time t0, the tcp module in host b advertised a window size of 2,048 bytes, and expected the next byte received to have a sequence number 3,000. You might need to adjust the window size if the receive buffer receives more data than it can communicate. Commonly used types of flow control are network congestion, windowing flow control and data buffer. Flow control in action the effect of flow control is only evident when a speedier sender transmits to a slower receiver the following example of flow control uses a receive buffer size of 100 k bytes. Ensure that you understand the tcp window size when you use sliding window for flow control.
