Still far too vague.
You're leaving so much "wriggle room" for yourself that you're not actually
saying much anything. Almost any results from a test would fit what you
say above. That's *NOT* good.
The questions you need to answer theoretically *carefully* are:
- do you think that eventually the network will regain its original
performance with time or not?
- if not, what can you say about the eventual steady state performance?
- how long will it take to reach it?

You were saying earlier 100*N?

Why 2500? What is your expectation for the routing info to converge?
