When ANY router becomes as reliable as a dumb TDM device, then maybe we can
begin collapsing the POP topology. However, the very nature of the Internet
almost prevents this reliability from being achieved (having a shared
control and data plane seems to be the primary culprit). There are routers
out there today that can single-handedly replace entire POPs at a fraction
of the rack, power, and operational cost. Hasn't happened, tho.
I don't like wasting ports for redundant n^2 or log(n^2) interconnect
either, but router and reliability mix like oil and water...
