5 step process by which a TCP/IP host sends data |
|
Definition
- Step 1.
- Create and encapsulate the application data with any required application layer headers. For example, the HTTP OK message can be returned in an HTTP header, followed by part of the contents of a web page.
- Step 2.
- Encapsulate the data supplied by the application layer inside a transport layer header. For end-user applications, a TCP or UDP header is typically used.
- Step 3.
- Encapsulate the data supplied by the transport layer inside an internet layer (IP) header. IP is the only protocol available in the TCP/IP network model.
- Step 4.
- Encapsulate the data supplied by the internet layer inside a network access layer header and trailer. This is the only layer that uses both a header and a trailer.
- Step 5.
- Transmit the bits. The physical layer encodes a signal onto the medium to transmit the frame
