摘要： The fast development of IP services forces the traffic flow in the networks to move gradually from Time Division Multiplexing (TDM ) services to packet data services. To adapt to the change, low-cost Ethernet technologies are introduced into the Metropolitan Area Network (MAN ). Ring network control protocols and ring network protection technologies are applied to guarantee manageability and reliability required in the telecom networks. The Ethernet Ring Protection (ERP ) and Resilient Packet Ring (RPR ) are two different ring protection technologies. The Transport Multi-Protocol Label Switching (T-MPLS ) network uses the T-MPLS Shared Protection Ring (TM-SPRing ) technology to provide ring protection. Carriers can expand the protection as needed and use appropriate ring technologies to meet the requirements of Carrier Ethernet (CE ).
