The packet header is checked to see which Layer 4 protocol to send it to. The packet is decapsulated, and the segment is sent up to Layer 4. At Layer 4, the destination port in the segment header is checked and the segment is decapsulated. The data is sent to the correct upper layer application. Depending on the application, it might go directly to Layer 7 or through 5 and 6. This process of encapsulation, transmission, and decapsulation makes data flow in an organized and manageable fashion down the OSI stack on the sender, across the transmission media, and up the OSI stack on the receiving host.
