Abstract: As a connection-oriented packet transport technology, Transport Multi-Protocol Label Switching (T-MPLS ) is an important bearer technology for Carrier Ethernet (CE ). This article starts with the technological characteristics of T-MPLS, then goes on to the latest T -MPLS standardization progress and challenges, followed by the description of T -MPLS based CE architecture. Next, the article covers several key technologies related with T -MPLS, including the data forwarding plane, control plane, network survivability, and Operation, Administration and Maintenance (OAM ). Finally, the article analyzes the applications of T-MPLS based CE.
