Detailed explanation-1: -Flow control based on the use of an output buffer. 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.

Detailed explanation-2: -Flow Control is an essential function of the data link layer. It determines the amount of data that a sender can send. It makes the sender wait until an acknowledgment is received from the receiver’s end. Methods of Flow Control are Stop-and-wait, and Sliding window.

Detailed explanation-3: -This is used in the data link layer. Rate based Flow Control These protocols have built in mechanisms to restrict the rate of transmission of data without requiring acknowledgment from the receiver. This is used in the network layer and the transport layer.

Detailed explanation-4: -There are two ways to control the flow of data: Stop and Wait Protocol. Sliding Window Protocol.
