T-MPLS Technology and Application on Carrier Ethernet

摘要

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.
