How does stop and wait protocol work?
A stop-and-wait ARQ sender sends one frame at a time; it is a special case of the general sliding window protocol with transmit and receive window sizes equal to one in both cases. After sending each frame, the sender doesn’t send any further frames until it receives an acknowledgement (ACK) signal.
Where is stop and wait protocol used?
It is used in Connection-oriented communication. It offers error and flows control. It can be used in data Link and transport Layers. Stop and Wait ARQ executes Sliding Window Protocol with Window Size 1.
What is the to time of stop and wait protocol?
In this, the sender will send one frame at a time to the receiver. The sender will stop and wait for the acknowledgment from the receiver. This time(i.e. the time between message sending and acknowledgement receiving) is the waiting time for the sender and the sender is totally idle during this time.
What is the main advantage of stop and wait protocol?
The main advantage of stop & wait protocols is its accuracy. Next frame is transmitted only when the first frame is acknowledged. So there is no chance of frame being lost. The main disadvantage of this method is that it is inefficient.
What is the difference between stop and wait and wait ARQ?
Working of Stop & Wait ARQ is almost like Stop & Wait protocol, the only difference is that it includes some additional components, which are: Time out timer. Sequence numbers for data packets. Sequence numbers for feedbacks.
How stop and wait protocol is used for reliable data transfer?
Simple Reliable Transmission: Stop and Wait protocol
- sender transmits one packet, then stops and waits.
- receiver transmits a special packet, an acknowledgment (ack), whenever it gets a data packet.
- once the sender gets the ack, it transmits the next data packet.
What is the maximum size of the send and receive windows for stop and wait protocol?
Sender can send a single packet at a time. Sender should wait until receiving the acknowledgement of the first packet to send the next packet. In Stop-and-Wait protocol, the maximum sending and receiving window size is 1. Chapter 3, Problem 5P is solved.
What is the difference between stop and wait protocol and pipelined protocol?
The main difference between Stop-and-wait protocol and Sliding window protocol is that in Stop-and-Wait Protocol, the sender sends one frame and wait for acknowledgment from the receiver whereas in sliding window protocol, the sender sends more than one frame to the receiver and re-transmits the frame(s) which is/are …
What is the difference between protocol and process?
As verbs the difference between process and protocol is that process is to perform a particular process or process can be (mostly british) to walk in a procession while protocol is (obsolete|transitive) to make a protocol of.
What is the stop and Wait protocol in computer network?
What is the Stop and Wait Protocol in Computer Network? It is the simplest flow control method. In this, the sender will transmit one frame at a time to the receiver. The sender will stop and wait for the acknowledgement from the receiver.
What is the difference between stop and wait and sliding window protocol?
The stop & wait protocol is half-duplex whereas sliding window protocol is full-duplex. The sender node sends a data packet to the receiver node. Then, waits for the feedback of the transmitted packet. As soon as the receiver node receives a data packet it starts processing it.
How to improve the efficiency of stop & wait ARQ?
The Stop & Wait ARQ is very less efficient because the sender window size is 1, which allows the sender to keep only one frame without feedback. So, the sender sends a data packet and waits for the feedback, and it gets the feedback it sends another data packet. In order to improve efficiency, we can increase the window size on both ends.
What are the disadvantages of the stop-and-wait algorithm?
The main shortcoming of the stop-and-wait algorithm is that it allows the sender to have only one outstanding frame on the link at a time. The sender should wait till it gets an ACK of previous frame before it sends next frame. As a result, it wastes a substantial amount of network bandwidth.
