Hello, Actually in My country Carriers chosen to go with IP-MPLS Routers directly.
Since whatever L2 networks tried to be smart, they will never be as intelligent as L3.
And as you said, MPLS-TP would be a choice to replace SONET/SDH, but actually even the SONET/SDH Service Trail structure is Not Efficient any more since the world is going toward Distributed services and Clouds, so L2 Tunnels even with SONET/SDH “OAM” Capabilities cannot fit in the future networks.
But For the Time being for UMTS Carriers, it is Useful to Replace EoSDH but not more in the future. So you can call it “Temp“solution.
The other main driver for carriers to choose MPLS-TP is they need the same Operations Style as they are used in SDH/SONE, since they don’t have the Knowles to Manage or operate large IP networks.
So also they consider it as Hybrid Step until their transport Engineers get the Knowledge of IP Networking “Or replacing them”.
So the Point why Many Carriers did not choose MPLS-TP is Because they Know, it is Just a Hybrid and in The coming Steps, they have to replace it any way, also it was not Cheap solution since Most of OLD SDH/SONET Equipments Did Not Support Native Packet Proceeding, and some Old Platform sub racks did not support the Native Packet Switch fabrics, also they needed Separate fiber resource than the TDM One, and New line & tributaries Cards.
The decision is Easy, if you have to do new Investment, would you choose the Temp Solution?! I will not
What a ridiculous thing to say, I'm taking this as you know nothing of how SDH transports PPPoE T1/E1 and ATM oh and how about packet over sonet?
What I am seeing is Ethernet being deployed over DWDM or CWDM which are the future "light" carriers
I come from a transmission background, let's see you deploy Ethernet or IP cross-continent without these technologies
For the record MPLS is a label technology and has the ability with AToM to be deployed across any genuine L2 frame structure, SDH DWDM transport them at real fast speeds, even with the advent of emerging MPLS-TP
