OONF Plugins
The OLSR.org Network Framework is mostly a collection of plugins (also called subsystems) which can be combined with the three main APIs to build a network application.
Plugins can depend on each other as long as there is no cycle. All plugins can expect all three main APIs being available.
There are multiple categories of plugins for OONF.
You can get a list of possible configuration options of a plugin by using the --schema parameter:
olsrd2 --schema=<name-of-plugin>
Dependencies between plugin categories
All plugins depend on the three OONF API's, OONF Common, OONF Config and OONF Core.
All OLSRv2 plugins depend on the NHDP Plugin, either directly or indirectly through the OLSRv2 Plugin.
Most Generic plugins, NHDP plugins, OLSRv2 plugins and Crypto Plugins depend on one or more Subsystem plugins.
Subsystems
The Subsystem plugins are a former 4th main API library. They contain most of the network and timer functionality of OONF and highly depends on each other.
All subsystems that start with os_ are operation system dependent and might have slightly different behavior depending on the operation system OONF was compiled for.
Most of the other plugins depend on multiple Subsystems.
All of the Subsystem Plugins export API functions that can be used by other Plugins.

NHDP plugins
The NHDP plugins are the IETF RFC 6130: Neighborhood Discovery Protocol (NHDP) implementation and all plugins that depend on it.
| auto_ll4 | automatic configuration of IPv4 interface addresses |

OLSRv2 plugins
The OLSRv2 plugins are the RFC 7181: Optimized Link State Routing Protocol v2 implementation and all plugins that depend on it. The OLSRv2 plugin itself of course depends on the NHDP Plugin.

Crypto plugins
The Crypto plugins are plugins that provide cryptographic algorithms or extensions for other OONF plugins.
| hash_tomcrypt | a wrapper for libtomcrypt that provides SHA 1/2 hashes and HMAC for the RFC5444 Signature Plugin. |
| rfc5444_signature | an API provider for other plugins to defines message and packet level RFC5444 signatures as defined in |
