The Encapsulation Process (Sending Data)
When you send information (like a Java command or a voice packet over a 5G slice), the data moves from the top of the stack to the bottom:
Application Layer (L7): Data is generated (e.g., an HTTP request or an email).
Transport Layer (L4): Data is broken into Segments. A header is added containing Port Numbers (Source and Destination) and sequencing information to ensure the packets can be reassembled.
