A metropolitan area network (MAN) resource control system, method and Access-Resource and Admission Control Function (A-RACF) device are disclosed, wherein, the A-RACF device comprises a MAN resource and policy control function (RPCF) module. The MAN network device comprises a MAN resource control enforcement function (RCEF) module. The system is connected via the MAN RPC module with the MAN RCEF module which needs to be controlled to control the QoS of the MAN resource. The MAN RPC module is used to make a MAN resource control strategy and generate the QoS policy. The MAN RCEF module is used to execute the QoS control according to the QoS policy sent by the A-RACF device.
