Answer: The Transport Layer of the OSI reference model is responsible for ensuring flow control so that destination station does not receive more packets that it can process at any given time.
Explanation: This is because;
The transport layer is the fourth layer in the OSI layered architecture which builds on the network layer to provide data transport that moves from a process on a source machine to a process on a destination machine. It is hosted using single or multiple networks, and very responsible for reliable data delivery ensuring packets are delivered in sequence, error-free and with little or no duplication or losses.
Since Transport layer helps one to control the reliability of a link through flow control, error control, and segmentation or desegmentation, It determines how much data should be sent where and at what rate.
The transport layer also offers an acknowledgment of the successful data transmission and sends the next data in case no errors occurred. TCP (Transmission Control Protocol )is the best-known example of the transport layer. Transport layers also retransmit messages if they arrive with errors.
