Referring to FIG. 1 , the PTN network resource management and scheduling method of the present invention is mainly performed by a PTN network resource management and scheduling system 1 for managing and scheduling. The PTN network resource management and scheduling system 1 includes a computer room. Management subsystem 11, a device management subsystem 12, a The circuit management subsystem 13 and a statistical management subsystem 14 are used for managing the location of the equipment room, the latitude and longitude information, the power supply loop information or other telecommunications room information, and the equipment management subsystem 12 is a device for managing the telecommunications equipment room. Information (device brand, model, rack, frame, card slot, card board, communication port, network management system, network loop, etc.), the circuit management subsystem 13 manages and records the physical layer circuit information. And virtual layer circuit information (LSP/PW), physical layer circuit information such as which port of the device is connected to both ends of the fiber, and its bandwidth, and the virtual layer circuit information is the circuit routing information and The bandwidth information used is the physical circuit and device information that is passed from the client to the computer. In addition, the statistics management subsystem 14 is used for statistics of various network resources, including the statistics of the equipment room. , device card usage statistics and circuit bandwidth statistics.

Please refer to FIGS. 1~2, the PTN network resource management and scheduling method of the present invention, and the step process thereof includes:
