* @addtogroup tcpip_communication_module TCP/IP communication module
*
* The TCP/IP communication module provides for a channel of
* communication for the \link ssltls_communication_module SSL/TLS communication
* module\endlink to use.
* In the TCP/IP-model it provides for communication up to the Transport
* (or Host-to-host) layer.
* SSL/TLS resides on top of that, in the Application layer, and makes use of
* its basic provisions:
* - listening on a port (see \c net_bind()).
* - accepting a connection (through \c net_accept()).
* - read/write (through \c net_recv()/\c net_send()).
* - close a connection (through \c net_close()).
*
* This way you have the means to, for example, implement and use an UDP or
* IPSec communication solution as a basis.
*
* This module can be used at server- and clientside to provide a basic
* means of communication over the internet.
