View notes tcp flow control from cs 102 at jaypee university it. 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. In closedloop flow control, congestion information is transmitted back to the sender. Commonly used types of flow control are network congestion, windowing flow control and data buffer. In the openloop flow control mechanism, receiver does not send any feedback to the sender and it is the most widely used flow control method. Tcp flow control the receiver side of a tcp connection maintains a receiver bu. Tcp flow control and data transfer transmission control. Tcp flow control receive side of tcp connection has a receive buffer. Difference between flow control and congestion control. Tcp flow control and error control flow control flow control regulates the amount of data a source. This figure illustrates an sample of tcp flow control and data transfer. Ensure that you understand the tcp window size when you use sliding window for flow control. Stallings, highspeed networks, tcp ip and atm design principles, prenticehall, 1998, sections 10.
