Hi Adrian, I agree that the requirements do not seem to be clear to everyone participating in this discussion. G.8110.1 does state "Transport MPLS is a connection-oriented packet switched transport layer network technology based on MPLS technology" which says a lot to folks familiar with transport network architectures and functional modeling of layer networks. I understand this may not be clear to others however. Perhaps one good way to think about T-MPLS is as an alternative to TDM transport. An LSR will relate to a T-MPLS transport device in a manner similar to the way it relates to a SONET or SDH transport device, and T-MPLS will provide transport services similar to those provided by SONET/SDH. From this perspective it may be easier to understand the functional subset selected for T-MPLS.
