In a communications network, peers can send messages to:

In a layered network model, each layer on one device has a corresponding peer at the same layer on the other device. Data travels through the stack, with each layer adding or removing its own headers, and finally the message is delivered to the peer in the same layer on the far end. That peer is the one responsible for handling that layer’s functions (for example, ensuring reliable transport or routing the packet). Layers above or below don’t directly receive the message from the far end; they interact with their own counterparts on the other side. So messages are exchanged between peers in the same layer across the network.
