How do you implement a stop and wait protocol?
Rule 1: Receive and then consume the data packet. Rule 2: When the data packet is consumed, receiver sends the acknowledgment to the sender. Therefore, the idea of stop and wait protocol in the receiver’s side is also very simple, i.e., consume the packet, and once the packet is consumed, the acknowledgment is sent.
What is stop and wait protocol explain stop and wait protocol in details?
Stop-and-wait ARQ, also referred to as alternating bit protocol, is a method in telecommunications to send information between two connected devices. It ensures that information is not lost due to dropped packets and that packets are received in the correct order. The above behavior is a basic example of Stop-and-Wait.
What is the mechanism of stop and wait flow control?
Stop-and-wait flow control is the simplest form of flow control. In this method the message is broken into multiple frames, and the receiver indicates its readiness to receive a frame of data. The sender waits for a receipt acknowledgement (ACK) after every frame for a specified time (called a time out).
What are the issues of stop and wait protocol at transport layer?
Problems :
- Lost Data.
- Lost Acknowledgement:
- Delayed Acknowledgement/Data: After timeout on sender side, a long delayed acknowledgement might be wrongly considered as acknowledgement of some other recent packet.
- Time Out:
- Sequence Number (Data)
- Delayed Acknowledgement:

What is the main advantage of stop and wait protocol?
Advantages of Stop and Wait Protocol The main advantage of this protocol is the accuracy. The next frame is sent only when the first frame is acknowledged. So, there is no chance of any frame being lost.
What are the drawbacks of stop and wait protocol?
Simple Reliable Transmission: Stop and Wait protocol disadvantages of stop-and-wait: fairly slow: the sender can send at most one new packet per RTT. not robust: if the ack can get lost, when the receiver gets a packet, the receiver cannot tell if it is a retransmission or a new packet.

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 main disadvantage of stop and wait protocol?
Which is are types of flow control?
Continue reading to learn more about each of these types of flow control valves and their functions.
- Gate Valves. Gate valves are general service valves primarily used for on/off, non-throttling service.
- Globe Valves.
- Pinch Valves.
- Diaphragm Valves.
- Needle Valves.
Is used in the stop and wait Protocol to overcome the issue of duplicate?
To eliminate duplicate packet problem sequence number is added to the data packet. So using packet numbers it can easily determine the duplicate packets.
What are the advantages and disadvantages 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 does stop and wait mean in javatpoint?
Here stop and wait means, whatever the data that sender wants to send, he sends the data to the receiver. After sending the data, he stops and waits until he receives the acknowledgment from the receiver. The stop and wait protocol is a flow control protocol where flow control is one of the services of the data link layer.
How does the stop and Wait protocol work?
Therefore, the idea of stop and wait protocol in the sender’s side is very simple, i.e., send one packet at a time, and do not send another packet before receiving the acknowledgment. Rule 1: Receive and then consume the data packet.
Why does javatpoint not send the next packet?
Since the data is not received by the receiver, so it does not send any acknowledgment. Since the sender does not receive any acknowledgment so it will not send the next packet. This problem occurs due to the lost data. Sender waits for an infinite amount of time for an acknowledgment.
