Technical field

The present invention relates to the field of communications, and in particular to a device management method, apparatus, and system.

The above integrated unit can be implemented in the form of hardware or in the form of a software functional unit.

In order to make the description of the embodiments of the present invention more clear, the following description and description are given in conjunction with the preferred embodiments.

The preferred embodiment of the present invention relates to a network management technology in the field of telecommunications, in particular, a floating IP address device such as a DPU, and provides a method for network management of a DPU device by performing power-on authentication.

If the IP address of the DPU changes frequently and the device is frequently powered off, if you want to use the existing network management model to implement DPU management, you need to support the virtual management network element (such as PMA) of the DPU to automatically identify the powered DPU. The device, and the two are linked to achieve various management of the DPU.

A preferred embodiment of the present invention describes a method for identifying and managing a floating IP device DPU. When the device is powered on, it receives registration information of the device, automatically identifies the device and associates it with the PMA, and pushes down the data configured on the PMA to the PMA. On the device, the basic functions of the network management of the DPU device are implemented.

The preferred embodiment of the present invention employs the following management architecture for the DPU device: PMAA - PMA - DPU. Among them, PMAA is PMA Aggregation, which is equivalent to EMS, and PMA is a virtual management network element of DPU.

The PMA and the DPU are in a one-to-one relationship. The PMA and the DPU are in one-to-one correspondence with the serial number (Serial Number, SN for short) of the DPU. When the DPU is powered on, the PMAA obtains the factory sequence of the DPU based on the registration information. No. SN and the actual IP address, and then find the PMA corresponding to the DPU according to the serial number SN. After the IP address is assigned, the network management system can manage the PMA as a real network element having an actual IP address.

For the data configuration of the DPU (manual or northbound interface), whether the DPU is online or not, the PMAA (EMS) accepts and completes the data configuration action of the specified PMA; then the PMA attempts to notify its DPU to take effect: if the PMA confirms the DPU If the current status of the DPU is offline, the DPU will go online and then push the complete configuration data.

In fact, for a physical device that actually exists, it is not the IP address that determines its uniqueness, but the device identifier such as the serial number of the factory. It is like a person. The only constant is the ID number, and the name is Can be modified. Therefore, as long as the serial number of the device can be obtained, the device can be uniquely identified, and the current IP address of the device is obtained through the correspondence between the serial number and the IP address, thereby realizing management of the device.

The components of a preferred embodiment of the invention include:

PMA: Before the DPU (equivalent to the above device) is powered on, the IP address network management of the DPU (equivalent to the above EMS) is unknown. Therefore, it is necessary to create a PMA according to the serial number of the DPU. When the PMA is offline, it is not used. The DPUs are actually connected to each other. All the configurations are saved on the NMS. When the PMA obtains the IP address and the DPU establishes a communication link, the PMA is converted to the online state. The NMS can be managed as a normal device.

Authentication registration module: After receiving the registration information of the DPU, the network management authentication registration module obtains the serial number (SN) of the DPU device and the actual IP address from the registration information.

PMA-DPU mapping library: maintains the mapping relationship between the SN sequence number and the PMA of each DPU device.

A preferred embodiment of the present invention also provides a method for identifying and managing a floating IP device, the method comprising the following steps:

Step 1: Create a PMA based on the serial number (SN) of the DPU device, and create a record in the PMA-DPU mapping library. The PMA is offline and can be pre-configured, but does not interact with the actual DPU device.

Step 2: When the DPU is powered on, obtain the assigned address through DHCP, and obtain the IP address of the network management server based on the pre-configured data, and contact the network management server to register. After receiving the registration information of the DPU, the NMS obtains the DPU. The serial number (SN) of the device (equivalent to the above device identification) and the actual IP address (equivalent to the first IP address described above).

Step 3: Obtain a PMA corresponding to the DPU according to the serial number (SN), and assign an IP address (corresponding to the second IP address) to the PMA, and the state is changed to online.

Step 4: Push the data configured on the PMA to the DPU device.

Step 5: Implement basic management of the DPU device: northbound, alarm, automatic discovery, performance, and policy.

Step 6: If the DPU device is offline, the PMA is switched to the offline state, waiting for the DPU device to be powered on again.

It can be seen from the above description that the preferred embodiment of the present invention solves the management problem for a large-scale DPU device compared with the related related art. For the deployment of a large-scale DPU device, no manual intervention is required, and the operation and maintenance cost is low.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described and illustrated with reference to the accompanying drawings.

4 is a flowchart of a device management method according to a preferred embodiment of the present invention. As shown in FIG. 4, the process includes the following steps:

Step S402: The authentication registration module: when the DPU is powered on, registers with the authentication registration module, and notifies the authentication registration module of the serial number (SN) and the actual IP address of the DPU device.

Step S404: PMA-DPU mapping library: Recording in the PMA-DPU mapping library is a mapping relationship between the DPU device and the PMA, and the mapping relationship is uniquely confirmed by the SN number of the DPU device, one-to-one correspondence, and mapping by PMA-DPU The library, the network administrator can find the PMA corresponding to the DPU according to the SN number of the device.

Step S406: PMA: All data configurations for the DPU are saved in the PMA. After receiving the DPU power-on registration information, the authentication registration module finds the unique PMA corresponding to the DPU device from the device IP address mapping library, and updates the IP address of the PMA. At this time, the PMA already has an IP address, and the network management system can perform normal management on the DPU device.

Step S408: Pushing the configuration data module: After the communication relationship between the PMA and the DPU is established, the PMA pushes the saved configuration data to the DPU device, and the DPU device configuration data is loaded, and the user service can be automatically activated.

In summary, through the foregoing embodiments and preferred embodiments of the present invention, the device identification device is used to solve the problem that the IP address of the device frequently changes and it is difficult to identify and manage; in addition, the configuration information is pushed through the PMA and the configuration information is pushed.
