It then contacts NNTP Server 5, which it knows, and provides it with the data.

The message is also received at NNTP Server 4 and processed: The header is enlarged around its name.

NNTP Server 3 receives the message as well, extends the header with its name and forwards the message to the NNTP Server 4 (which it knows).

NNTP Server 2 receives the message and inserts its name into the header.

It recognizes NNTP Server 2 and NNTP Server 3, and forwards the message onto both.

NNTP Server 1 provides the message with a unique message ID and adds its name to the header.

The user behind NNTP Client 1 writes a new message (or new article) and sends this data to NNTP Server 1.

The individual messaging steps that are depicted in this diagram can be summarized as follows: As a result, the longer a client was “offline”, the more time the updating process utilizes after the connection has been established. As a result, this means that after the establishment of the connection to an NNTP server, a client first downloads all messages that were published since the last connection to the server.

All the other clients who would like to participate in the particular conversation can download this message or article at any time in order to establish the current status of the newsgroup. The basic concept of Usenet allows for a new message that is sent from an NNTP Client to any NNTP server to be stored on this same server. The NNTP itself has access to the application layer and for this relies directly on the TCP protocol, which has the advantage of ensuring both a secure and reliable transfer of data. For this communication the IANA ( Internet Assigned Numbers Authority) has provided TCP-Port 119, which in this case is solely reserved for the transfer protocol – a TCP/IP network such as the Internet is as a result the underlying basis for the information platform.

NNTP is a text-based protocol and allows for the alternating exchange between client and server: Therefore, for every NNTP inquiry, an NNTP reply is expected.
