Hi everyone,

Hello!

I'm a newbie to BIRD who ran across it from freshmeat.net.

Being a newbie, I have some newbie questions.

How efficient is it to sync with kernel space routing tables if the routing tables change rapidly?

Look into source code. I'm not sure, but of course it's not too efficient.

How often does a routing table change with a typical server configuration and typical server traffic?

It depends on the network topology. In my small network it happens every minute. But I don't run BGP in it. I can imagine, it can happen much more often.

Lastly besides the portability, why implement a userspace daemon that is required to sync with the kernel when kernel space modules could be written to directly manipulate the routing tables themselves?

Last I met Martin, we discussed about building BIRD as a linux kernel module. Let's say, it's a future plan.

Thanks for answering these questions. Currently, I am EXTREMELY interested in this project, and would like to potentially put some development time into BIRD.

Welcome!
