![]() Total time= Td(Transmission Delay) + Tp(Propagation Delay for data frame) + Tp(Propagation Delay for acknowledgment frame) Hence, the total time required to send a frame is: The propagation delay for sending the data frame and the acknowledgment frame is the same as distance and speed will remain the same for both frames. This can be understood by the diagram below: When the sender gets the acknowledgment(ACK), then it will send the next data packet to the receiver and wait for the acknowledgment again and this process will continue as long as the sender has the data to send. the time between message sending and acknowledgement receiving) is the waiting time for the sender and the sender is totally idle during this time. The sender willįor the acknowledgment from the receiver. In this, the sender will send one frame at a time to the receiver. In this blog, we are going to learn about the Stop-and-wait protocol. There are mainly two ways in which this can be achieved i.e. The flow control method will keep a check that the senders send the data only at a rate that the receiver is able to receive and process. Methods will help in ensuring that the data doesn't get lost. ![]() Suppose a situation where the sender is sending the data at a rate higher than the receiver is able to receive and process it, then the data will get lost. ![]() ![]() ![]() While sending the data from the sender to the receiver the flow of data needs to be controlled. ![]()
