Transport MPLS (T-MPLS) the Transport Technology for Packet-Based Networks

To stay profitable, service providers must focus on introducing revenue generating services while controlling their cost structures. At the same time, they must respond to the demand placed by new bandwidth-hungry services for capacity and aggregation functionality in the underlying transport infrastructure. To achieve this, transport networks for packet-based services and networks must continue to provide the same levels of reliability, availability and manageability that service providers have come to expect from circuit-based infrastructures. This paper describes how the Transport-MultiProtocol Label Switching (T-MPLS) architecture an emerging solution developed by the ITU-T answers this challenge.
