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:
Dependencies between plugin categories
All plugins depend on the three OONF API's, OONF Common, OONF Config and OONF Core.
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.
