<br>
Complicated. We don't really have an architecture diagram.<br>
<br>
For detailed API docs, see http://doc.freeradius.org/<br>
<br>
As for the rest of your questions, they are both too vague and too<br>
specific. The main reason to ask questions is to solve a particular<br>
problem. You're asking a series of vague questions "how does it work",<br>
along with detailed questions "why is it done this way".<br>
<br>
They're all nice questions, but they can usually be answered by<br>
reading the source. The code is VERY well commented. I see no reason<br>
to cut & paste those comments here.<br>
