In summary, the embodiment of the present invention can pre-configure or file mode the device power consumption estimation in the DPU device, and set the working state policy under different service power consumption budget results; when the device starts to power on, the device hardware is detected. Connection, user interface type/number, PD part voltage/current and other electrical parameters; based on the detection result, the device combines the power consumption estimation in the policy configuration, calculates the device power consumption and PSE power supply capability, and obtains the current service power consumption of the DPU device. The device calculates the service status of the device according to the service power budget result and the policy configuration module, and determines the service opening mode. The device converts the service control command according to the policy control command generated by the above process to complete the device service control operation to meet the requirements. Equipment operating power requirements.

In the reverse power supply mode, the technical implementation of the DPU device operating state control method is as follows:

1. In the policy configuration, estimate the power consumption value and power supply of the DPU device.

The power consumption of the DPU device can be abstracted into three parts, one part is the power consumption of the system part, mainly for the CPU chip, the single board, the driver chip, etc.; the part is the power consumption of the uplink port (the power consumption of the PON interface or the GE interface is different); Power consumption for the user port. In order to ensure the safe operation of the equipment, some power reserve should be reserved. The above data are estimated by the theoretical value and the empirical value weighted, and are preset in the strategy.

The device state power consumption estimation used in the embodiment of the present invention mainly records the following data: full power consumption of different types of main control boards and power consumption estimation under minimum working conditions; different types of uplink power consumption and minimum work Power estimation in the state; power consumption estimation under different power consumption and minimum working state of different types of user ports; maximum power supply estimation of different types of PSD; equipment power consumption reserve estimation.

2. Estimation of power consumption of different working states during DPU device startup.

During the startup of the device, the device hardware type detection is performed to determine the model of the main control board, the type/number of uplink interfaces, the type/number of user interfaces, and the type of PSE model/quantity.

The power consumption estimation of different working states used in the embodiments of the present invention mainly includes the following contents:

1) DPU maximum operating state power consumption (ie maximum working power consumption), DPU equipment works at full power consumption per part.

By calculating the estimated value in the strategy, the maximum power consumption P _dpu-max of the DPU device is calculated as the sum of P _sys-max , P _uplink-max , P _port-max and the device power consumption reserve weight; wherein, P _dpu-max is The maximum operating power consumption of the DPU device; P _sys-max is the maximum power consumption of the DPU device system. It mainly considers the CPU occupancy, the working state of the driver chip, and the power consumption of each device in the device. It can be based on theoretical values and empirical values. Weighted estimation; P _uplink-max is the maximum power consumption of the _uplink port, which can be estimated according to the type and quantity of the uplink port and the traffic model; P _port-max is the maximum power consumption of the user interface, which can be estimated according to the user port type and quantity and traffic model. .

2) The DPU minimum working state power consumption (ie, the minimum working power consumption) only ensures that the DPU device CPU works normally, the uplink management channel is normal, and the user interface service is closed.

The DPU device minimum operating state power consumption P _{dpu-min is} estimated as the sum of P _sys-min and P _uplink-min and the device power consumption reserve weight; where P _dpu-min is the power consumption of the DPU device in the minimum working state; P _{sys -min} is the minimum power consumption of the DPU equipment system, which can be weighted according to the theoretical value and the empirical value; P _uplink-min is the minimum power consumption of the _uplink port, which can be estimated according to the type and quantity of the uplink port and the traffic model.

3) PSE power supply capacity calculation.

When the DPU device starts up, it detects the PD type, the number, and the electrical parameters such as the input and output voltage and current of the power receiving part, removes the conversion efficiency and other factors, and calculates the PSE maximum power supply P _pse .

3. According to the comparison between P _pse and the current P _dpu-max and P _dpu-min estimation of the DPU device, calculate the service power budget that the DPU device can provide, analyze the working state strategy, and generate policy control commands according to the result, and transmit Give the business control module.

The analysis of the strategy used mainly includes:

Scenario 1: When P _pse >P _dpu-max , it indicates that the PSE is fully powered, and the service power budget can satisfy the DPU device working in each state. The policy analysis generates policy control instructions and passes them to the service control module through the policy control module.

Scenario 2: P _dpu-min <P _pse <P _dpu-max , DPU equipment may have power consumption overload, can analyze the working state of DPU equipment, and generate corresponding policy control commands, which are transmitted to the service control through the policy control module. Module to ensure that the device is working properly.

For the P _dpu-min <P _pse <P _dpu-max scenario, the control strategy for the working state of the DPU device in the embodiment of the present invention is: based on the DPU minimum working power consumption P _dpu-min and the PSE power supply power P _pse as a reference, The service power budget of the DPU device can be compared with the current user interface service configuration power consumption of the DPU device to determine whether the DPU device can work under the current user service configuration power consumption condition. as follows:

1) The user service configuration power consumption meets the service power budget, indicating that the device has sufficient power consumption, and the user service can be opened according to the configuration requirements, and the notification is reported, and the module generates corresponding policy control commands.

2) The user service configuration power consumption does not meet the service power budget, and the service power budget can be satisfied by shutting down part of the user service channel, reducing the port transmission power (reducing the port activation rate), or dynamically combining the two according to the policy. Report the police, the module generates the corresponding policy control instructions.

3) If the strategy still fails to meet the service power budget requirements, the DPU device runs in the minimum working state (ie, the minimum working power state or the minimum state), does not provide user services, and reports alarms, and the module generates corresponding policy control commands.

4) In an extreme scenario, if the single PSE is powered, after the above working state policy control is completed, the DPU device can work normally and provide user services, but the power consumption is in a critical state. For example, the power consumption of the device may be changed due to the running state of the chip such as the CPU. Frequently, the power consumption is out of bounds, causing the device to be in an unsafe working state. DPU devices can reduce the impact of this aspect through software restrictions, such as restricting software functions that are not commonly used but affect CPU occupancy, such as limiting software version upgrades, restricting file upload and download, limiting the number of management logins, and limiting SELT/DELT and other High CPU occupancy to ensure DPU devices work properly.

Scenario 3: When P _pse <P _dpu-min , the DPU device cannot work in the minimum state, and the PD part needs to be closed. The corresponding command is transmitted to the service control module through the policy control module, and the device stops starting.

4. The embodiment of the present invention can be pre-placed in a DPU device by means of a configuration or a policy file, etc., and the DPU device reads and performs analysis at startup. After the device hardware upgrade or software optimization needs to modify the power consumption estimation and modify the working status definition, the policy file can be updated by local modification or centralized delivery.

Further explanation will be given below with reference to the embodiments shown in FIGS. 3 to 5.

3 is a basic diagram of a DPU device according to an embodiment of the present invention. As shown in FIG. 3, in addition to the external PSE power supply device 100 and the DPU power receiving module PD portion 11, the DPU device power consumption can be abstracted into the user interface portion 21 The upper port portion 31 and the system portion 41. The power consumption of these parts can be estimated by the theoretical value and the empirical value weighting, and is preset in the DPU device through configuration or policy files as a reference for strategy analysis.

FIG. 4 is a schematic diagram of a policy implementation related module and a relationship diagram provided by an embodiment of the present invention. As shown in FIG. 4, a plurality of modules jointly implement the functions of the computing module 10, the comparison module 20, and the processing module 30 shown in FIG. 2.

The device power-on detection module 12 detects the system hardware model, the type and number of the uplink port, the type and number of the user port, the PD power-receiving part model, and the electrical parameters such as voltage/current during the power-on process of the DPU device.

The policy configuration module 22 includes two parts. The first part is the device power consumption reference value part, and provides the DPU device system, the uplink, and the estimated power consumption of each part of the user. The different models and different interface types have different estimated values; the second part is work. The status policy configuration part provides reference for the device working status policy under different service power budget results. The application scenario is as follows:

Scenario 1: The business power budget is sufficient, and the strategy is that the device can work in multiple states;

Scenario 2: The service power budget does not meet the maximum working status of the device. The strategy is to reduce the part of the user service channel, reduce the port transmission power (reduce the port activation rate), or dynamically combine the two to meet the service power budget. It can work only in the minimum working state to satisfy the normal management channel. After the adjustment, if the power consumption is in a critical state, it can be fine-tuned by software restrictions, such as limiting some software functions that are not commonly used but will affect the CPU share, such as limiting software version upgrade, limiting file upload and download, limiting the number of management logins, and limiting SELT. Other high CPU share functions such as /DELT to ensure that the DPU device works properly.

Scenario 3: The service power budget does not meet the minimum working state of the device, and the strategy is to turn off the PD power receiving part.

The power consumption calculation module 32 calculates the maximum operating state power consumption and the minimum working state of the device according to each part of the power consumption estimation value preset by the policy configuration module 22 according to each component of the device detected by the device power-on detection module 12. It consumes PSE power supply capability and derives the current service power budget of the DPU device.

The policy analysis module 42 performs the work state policy analysis and outputs the result according to the service power budget result obtained by the power consumption calculation module according to the policy formulated by the policy configuration module.

The policy control module 52 generates a policy control command according to the result obtained by the policy analysis module, and converts the service control command to the service control module 62.

The service control module 62 executes a service control command sent by the policy control module to perform service control on the DPU device. ;

Step S206: P _dpu-min <P _pse <P _dpu-max , the DPU device service power budget does not meet the maximum working state of the device, and the service power budget that the DPU device can provide is calculated.

Step S207: determining whether the service power budget meets the current user service configuration. If the service power budget meets the current user service configuration, the user service is activated according to the current configuration requirement, and the notification is reported, the output policy is analyzed, and the policy control module is transferred to the policy control module. Step S213: If the service power budget does not meet the current user service configuration, step S208 is performed.

Step S208: The service power consumption budget does not meet the power consumption of the user service configuration, and according to the policy, the part of the user service channel is closed, the port transmission power is reduced (the port activation rate is lowered), and the alarm is reported.

Step S209: It is determined whether the user service configuration power consumption is in a preset critical range of the service power consumption budget after the adopting the policy of step S208, that is, whether the power consumption is in a critical state, for example, in a power consumption critical state, step S210 is performed. If it is not in the critical state, step S213 is performed.

Step S210: The software function of the device limitation part is very useful but affects the CPU occupation rate, and is analyzed according to the output policy and transferred to the policy control module.

Step S211: Continue to check whether the service power budget meets the user service configuration. If yes, the output policy is analyzed and transferred to the policy control module, and step S213 is performed; if not, step S212 is performed.
