CCN lite port of RIOT
|
|
=====================
|
|
|
|
RIOT's support for CCN messages is based on the work of [Christian Tschudin from University of Basel](http://cn.cs.unibas.ch/people/cft/) [(CCN-lite code available here)](https://github.com/cn-uofbasel/ccn-lite).
|
|
|
|
The network stack can handle multiple faces based on the transceiver or from the local device via RIOT's message system.
|
|
To communicate with the stack, one can send messages via the RIOT message system to the CCN-lite relay thread or via a physical network transceiver.
|
|
|
|
All incoming messages are processed in the main IO loop, which you can find [here](ccn-lite-relay.c#L302).
|
|
|
|
The public API of the ccn network stack is defined in `sys/net/include/ccn_lite/ccnl-riot.h`.
|
|
Client related functions are defined in `sys/net/include/ccn_lite/util/ccn-riot-client.h`.
|
|
|
|
To work with the CCN-lite network stack, only these two API declarations need to be considered.

Running Test Application
|
|
------------------------
|
|
|
|
Test applications are provided in the example directory.
|
|
|
|
### ccn-lite-client
|
|
|
|
The CCN-lite client uses the RIOT shell for user interaction.
|
|
The network stack is started on demand in its own thread. You have to enter `ccn <CS size>` in the shell.
|
|
Further details are explained in `examples/ccn-lite-client/README.md`.
|
|
|
|
### ccn-lite-relay
|
|
|
|
The CCN-lite relay is an application without interactive user control.
|
|
Further details are explained in `examples/ccn-lite-relay/README.md`.
|
|
|
|
Hardware support
|
|
----------------
|
|
|
|
The CCN-lite stack is currently tested and proved to run on the native port of RIOT and the MSBA2 embedded hardware.
|
|
On the MSBA2 platform (32 Bit) CCN-lite only needs a stack of 800 bytes.
|
|
It uses the heap for the CS, FIB, and PIT.
