IXP

Sat Apr 18 19:51:54 UTC 2009

I have been looking at ams-ix and linx, even some african internet  
exchanges as examples. But seeing how large they are(ams-x & linx) and  
we are in the startup phase, I would rather have some tips/examples  
from anyone who has been doing IXP for quite awhile.
So far all the responses have been very helpful.
