My guess is if any providers were deploying it, it would be incumbent telco's. But one would be hard-pressed to find a decent incumbent, today, that hasn't already deployed an IP/MPLS backbone in parallel to their legacy network. That, then, leaves you with existing operators who run both legacy and IP/MPLS networks, to consider MPLS-TP as a migration path from SDH/SONET to anything above an STM-64/OC-192, i.e., 40Gbps Ethernet, 100Gbps Ethernet, 400Gbps Ethernet, 1Tbps Ethernet, e.t.c., and sub-rates thereof. As pretty much all optical vendors are now incorporating MPLS-TP support into their devices, I posit that we are likely to see MPLS-TP deployments in the optical plane, as opposed to typical routing hardware like Cisco, Juniper, Brocade, ALU et al, as those (for now) do a better job at normal MPLS forwarding, even if they are sporting some form of MPLS-TP support. Also, it might give legacy operators more comfort and peace of mind to implement these "packet things" in optical devices than on IETF routers/switches. Cheers, Mark.
