In order to facilitate understanding of the embodiments of the present invention, the SDN network-based power supply device management method according to the embodiment of the present invention is further described below:
in an SDN network, as shown in fig. 4, a cloud platform of a service orchestration layer (application layer) or a third-party integrated cloud platform management server provides relevant computing resources such as a CPU, a memory, and a storage. The SDN controller at the network control layer is connected with the cloud platform through a northbound interface and is responsible for managing network equipment, and the SDN controller issues virtual service configuration to the network equipment according to the virtual service condition of the cloud platform to ensure that the connectivity of upper-layer virtual services is managed and accessed to physical equipment of the infrastructure layer through a southbound interface. The infrastructure layer is composed of network hardware devices including Power Over Ethernet (POE) switches.
In the SDN network-based power supply device management method of this embodiment, a power supply management function and a management policy of a POE switch on an infrastructure layer are moved up to an SDN network control layer for implementation.
The first implementation mode comprises the following steps:
the bottom layer basic module acquires information of the bottom layer power supply equipment, namely the POE switch, through integrated tools (SNMP, SSH and the like) in the ODL. The information of the POE switch may include, for example, values of an ip address, a device model, a port number, a current power supply power of the port, a default maximum external power of the port, a port power supply level, a total power supply power of the POE switch, a remaining power supply power value, and the like obtained from the POE switch.
The bottom layer basic module synchronously writes the acquired equipment port information of the POE switch into an ODL database for storage;
the ODL-POE main control module monitors the change of the information in the database to obtain all values of the power generation of the power supply equipment;
if the web interface configures the power supply total power limit of a single POE switch device, the power supply total power calculated and obtained in the power supply strategy management unit exceeds a preset value, and then an instruction is issued to close the power supply of the port corresponding to the POE switch.
The second embodiment:
and calculating according to the port power supply priority information of the POE switch equipment, the total power value of the POE switch, the residual power value, the power and the quantity of the power supply ports. If the residual power of a certain POE switch in the network is 20W, the maximum power of all ports is 30W, and at this time, a port with a high power supply priority is newly added in the network, the power supply strategy is preset to close the power supply of the port with a low priority, and power release is performed, so that the current residual power value is greater than 30W. Therefore, the POE power supply management strategy based on the application layer can be increased or updated simply and conveniently.
The third embodiment is as follows:
the main control module senses the online of the new equipment by monitoring the change of the database. The power of the external power supply of the current POE switch reaches the maximum power of the power supply, if a new powered device is added, a power supply strategy is preset, the port with the low priority is powered off, and the port with the high priority is newly added for power supply.
In this embodiment, the power supply priority of the POE power supply port may be preset by the user, for example, the port 1-10 is set to be high-priority power supply, and the port 11-20 is set to be low-priority power supply. The maximum power supply power of each port is 30W, the overall external power supply power of the POE switch is 300W, and theoretically, the POE switch can only support the power supply of 10 ports. If 10 ports with low priority are powered on, and the port with high priority is required to be powered on at the moment, the ODL-POE main control module closes the power supply of the power supply port with the low priority according to the power supply priority of the port recorded by the database, and releases power.
The fourth embodiment:
for ports requiring high-power supply such as wifi6, the temperature of the POE power supply port can be collected for safety monitoring, and alarm and port power supply shutdown are performed when the temperature exceeds a temperature threshold value.
The fifth embodiment:
the state of a powered device or other terminals below the POE switch is monitored by using network traffic collection of the SDN, for example, the SDN resets the powered device for network fault recovery by collecting port power supply information and sampling port data and switching power supply of a port.
Embodiment six:

And the SDN controller acquires power supply log information from the log server through a northbound interface provided by the log server and displays the power supply log information on a front-end control interface.
