Flow control can typically be found at which layer of the OSI?

The Transport layer is responsible for flow control via the TCP/IP protocols of TCP and UDP. The Network layer is responsible for logical addressing of network nodes. The Data Link layer is responsible for the framing of data and the physical addressing of local nodes. Although the Data Link layer can perform a type of flow control, the Transport layer is synonymous with flow control. The Session layer is responsible for the setup of the dialog between two hosts.
