In a hierarchical network structure:
For example, in the Open Systems Interconnection (OSI) model, a protocol data unit (PDU) will be established at each layer of the transmission system. The PDU contains information from the upper layer and additional information from the entity of the current layer, and the PDU will be transmitted to the next lower layer.
The physical layer actually transmits these PDUs in the form of framed bit streams, which are constructed by higher layers of the protocol stack. The receiving system transmits these data packets through the protocol stack from bottom to top, and separates the related information in the PDU at each layer of the protocol stack.
