Re: Distributed Router Fabrics

[Mike Hammett <nanog () ics-il net>]

I don't find this explained in any of the literature I've looked at so far. 


In a distributed fabric, where is the traditional control plane run? Say I've got 100 BGP sessions of upstream,peer, 
and downstream across ten routers. Is each pizza box grinding this out on its own, or is the work done on the x86 box 
mentioned in the larger installations? If each box is doing it on its own, are there route reflectors somewhere making 
all of the decisions?

I've noticed that the whitebox hardware vendors are pushing distributed router fabrics, where you can keep buying pizza 
boxes and hooking them into a larger and larger fabric. Obviously, at some point, buying a big chassis makes more 
sense. Does it make sense building up to that point? What are your thoughts on that direction?
