What is flow control and buffering?

FLOW CONTROL AND BUFFERING: Flow control is done by having a sliding window on each connection to keep a fast transmitter from over running a slow receiver. Buffering must be done by the sender, if the network service is unreliable. The sender buffers all the TPDUs sent to the receiver.

How does buffer help controlling the flow?

In the output buffer flow-control approach, a buffer at the output level helps to slow down the frequency of the upstream data when the next router is congested (Fig. 4). For that purpose, we define three levels that quantify the load of a router: under-loaded, loaded, or congested.

What is flow control what are two major protocols to achieve flow control and explain in detail any one mechanism?

There are two ways to control the flow of data: Stop and Wait Protocol. Sliding Window Protocol.

Which is the best definition of the buffering hypothesis?

The buffering hypothesis is a theory holding that the presence of a social support system helps buffer, or shield, an individual from the negative impact of stressful events. The buffering hypothesis has been researched in terms of whether or not social support systems lengthen a person’s longevity, health,…

Why is flow control important in data link layer?

Flow control is design issue at Data Link Layer. It is technique that generally observes proper flow of data from sender to receiver. It is very essential because it is possible for sender to transmit data or information at very fast rate and hence receiver can receive this information and process it.

What is the purpose of flow control in TCP?

The purpose of flow control is to let the sender know that the receiver is slower. For that, a sender application should be informed in case of a slow receiver. Generally, the TCP module informs the sender, while sending data.

How is cortisol related to the buffering hypothesis?

Cortisol can suppress the digestive, reproductive, and immune systems. When the immune system is suppressed, there is an increased risk for getting sick. Below are three reasons the buffering hypothesis holds true. Taking care of a newborn can be exhausting and stressful.
