One of my DS3/DS1 vendors recently told me of a plan to use MPLS for part
of the route inside their switching center. I said "not with my circuits
you won't". Once they understood that I was willing to take my business
elsewhere or simply do without, they decided that an M13 was worth having
after all. My advice is, walk softly but carry a big stick. When we all
say "everything over IP" that means teaching more devices how to speak
802.11 or other packet-based access protocols rather than giving them ATM
or F/R or dialup modem circuitry. It does *not* mean simulating an ISO-L1
or ISO-L2 "circuit" using a ISO-L3 "network". (Ick.)
