【Abstract】 RPR is a new protocol of MAC layer and technology of MAN,having some main characteristics,such as spatial multiplexing,dynamic bandwidth allocation and class of service.To guarantee service quality of business,RPR defines three kinds of service level,including Class A,Class B and Class C.Being a part of TMN,transmitting network management system is a kind of SDH management network and its realization uses three-layer structure.Realization of RPR business classification in transmitting network management involves with three Qx interface commands:setting Ethernet service property on data plate,setting the static destination site URL of data plate and setting the choice of RPR loop port.更多还原
