XORP's FEA process is responsible for talking to the underlying 
forwarding plane. It supports *BSD, Linux, MacOS X, and Microsoft Windows.

Over the last year there was a refactoring where the forwarding table 
management got split into plugin-like modules. It is written in C++ 
although it's likely this split might make integration into other 
projects easier.

Normally that support all goes into a single process, rather than being 
linked into many.
