I'm trying to understand the OSI layer model.
I often read that flow control in mainly handelt in Data Link Layer (L2) and Transport Layer (L4). But I cant find what methods thay use.
Does the Transport layer uses flow control by TCP by useing window mechanism?
But what/how does the data link layer does flow control?

it has a different approaches in transport layer and data link layer ... because -> transport layer is an end to end communication that is communication between node to node (sender and receiver).. -> where as in data link layer there will be multiple intermediate nodes(routers) present hence flow control mechanism is with respect to adjacent nodes in path between sender and receiver here therefore they have different approaches
