[Xorp-hackers] Help

[wubaochuan]

Hello everyone,
     I want to use XORP in the following way, you can see the attachment 
file as_en.jpg.
     The Control Node acts as central control node, the routers act as 
Forwarding Node. XORP runs on Control Node and Forwarding Nodes, but the 
XORP software runs on Forwarding Node does nothing but sends LSAs to the 
Control Node, and the Control Node can construct a graph of the AS, and 
the Control Node can calculate routes for each Forwarding Node. After 
that, the Control Node sends routes to the Forwarding Nodes, and the 
Forwarding Nodes install the routes and forward packets.
       When the Control Node calculates routes for each Forwarding 
Nodes, people can control this process.
       In order to do the things above, I have to modify the XORP source 
code(OSPF source code). I want to know:

       Where should I begin? I have read several articles including 
/Xorp Design Overview, XORP Inter-Process Communication Library 
Overview, XORP Libxorp Library Overview, XRL Interfaces Specifications 
and Tools, An Introduction to Writing an XORP Process. /But I do not 
know what to do next. Now I am reading /An Introduction to Writing an 
XORP Process /again, I hope I can learn more about the architecture of 
the source code of XORP.


       Thank you.

       Yours
       Chuan
