Time Division Multiplexing (TDM) transport networks are evolving to packet-oriented, and a variety of carrier-class packet transport technologies have emerged. Provider Backbone Bridge with Traffic Engineering (PBB-TE) is a connection-oriented packet transport technology that provides good scalability and manageability, and guarantees Quality of Service (QoS). Generalized Multi-Protocol Label Switching (GMPLS) is a mature transport network control plane technology that supports multiple data planes with different switching granularity. GMPLS-controlled PBB-TE is a promising solution for Packet Transport Networks (PTN)
