TCP/IP communication module
The TCP/IP communication module provides for a channel of communication for the SSL/TLS communication module 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
).mbedtls_net_bind()
- accepting a connection (through
).mbedtls_net_accept()
- read/write (through
.mbedtls_net_recv()
/
)mbedtls_net_send()
- close a connection (through
mbedtls_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.
