29 * The TCP/IP communication module provides for a channel of
30 * communication for the \link ssltls_communication_module SSL/TLS communication
31 * module\endlink to use.
32 * In the TCP/IP-model it provides for communication up to the Transport
33 * (or Host-to-host) layer.
34 * SSL/TLS resides on top of that, in the Application layer, and makes use of
35 * its basic provisions:
36 * - listening on a port (see \c mbedtls_net_bind()).
37 * - accepting a connection (through \c mbedtls_net_accept()).
38 * - read/write (through \c mbedtls_net_recv()/\c mbedtls_net_send()).
39 * - close a connection (through \c mbedtls_net_close()).
41 * This way you have the means to, for example, implement and use an UDP or
42 * IPSec communication solution as a basis.
44 * This module can be used at server- and clientside to provide a basic
45 * means of communication over the internet.
