Connection-oriented server

The server normally waits on a known address for service requests. The server remains inactive until a client sends a connection request to the address of the server. The server then “wakes up” and serves the client by executing the relevant actions for the client request.
The server is accessed via a known Internet address.

You will find an example of a connection-oriented server for both AF_INET and AF_INET6, and for AF_ISO, below.
