Embodiment Construction

[0043] The following describes in detail in conjunction with specific embodiments.

[0044] The invention provides a PCI fast bus energy management method, which is applied to a distributed system based on PCI Express bus transmission on a backplane and data forwarding through a Switch or a bridge device. The system includes a main control board and a plurality of service boards . Wherein, each service board generally has an independent CPU for functions such as classification and search of data packet forwarding. After the CPU on the service board is powered on, it can also manage its own system, control the PCI Express bus device of the service board and the backplane interface, and make the device enter and exit different device working states or device power-saving states. The main control board generally implements the initialization of the system PCI Express link and the maintenance and control of status changes and configuration changes. The Switch device or bridge de...

Abstract

The present invention discloses a management method of the energy of a PCI Express bus. A main control board detects whether a service board is present, if not present, then the main control board does not provide electricity to the service board, and the PCI Express bus link corresponding to the service board is configured as a state of link power off; if present, then the main control board provides electricity to the service board, and when the service board detects that an interface board is present and that the connections on physical interfaces are normal, the PCI Express bus link corresponding to the service board is configured as a link working state, and a PCI Express bus port of the service board is configured as a device working state. The present invention realizes information transmission by the IPC channel cooperation existing in the system, and as a result, the states of the present detections of the service board, the interface board and the physical interfaces of the interface board and the states of the PCI Express bus link on a control system and a device come into a state of low energy consumption, realizing the energy management of energy saving.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a PCI Express (Peripheral Component Interconnect Express, Peripheral Component Interconnect Express) bus system and an energy management method thereof. Background technique [0002] Communication operators and enterprise network customers pay more and more attention to OPEX (Operating Expenditure, operating cost), and the energy consumption cost of equipment is one of the largest costs after operation. Equipment with high power consumption is bulky, difficult to install, and problems such as noise and heat dissipation are difficult to solve. Therefore, in order to solve these problems, the cost of each link in production and maintenance has been increased, and customer satisfaction has been reduced. For devices with lower power consumption, since the devices themselves generate less heat, smaller power supplies and fewer or lower-noise fans can be used to remove heat from ...
