摘要： The Metro Ethernet Forum (MEF ) put forward the concept of Carrier Ethernet (CE ) to improve Ethernet technology and make it a transmission convergence layer solution for Next Generation Network (NGN ). Provider Backbone Transport (PBT ) is the result of the enhancement and improvement of the early Ethernet technologies and it is the new version of CE implementation technology and standard which is promising. Through studying the PBT- related technologies, PBT network structure, PBT advantages as the transmission convergence layer solution and its trend of future development, it is concluded that PBT can be used as the preferred technology of the transmission convergence layer in the NGN, though there are some problems to be solved for PBT.
