![]() The example of the stop-and-wait protocol is the RPC (Remote Procedure Call) because it works in the similar pattern where the subroutine calls are implemented from the program in one device to the library routines on another device. The transmission mode of the protocol is half duplex, as the sender transmits data to the receiver at a time and receiver sends the acknowledgement when data is received. When the receiver sends an acknowledgement to the sender, it proceeds further and sends another frame. In this protocol, the sender sends a frame then waits for the acknowledgement. The stop-and-wait protocol has emerged as a solution to this problem. In a communication, if the speed of transmitting data at the sender end is very much higher than the speed of reception of data at the receiver end, how the network is going to deal with these kinds of cases? It requires the working speed of sender and receiver should be unvarying.
