Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a resource management method according to an embodiment of the present invention includes:
102, generating and storing resource mapping information according to the attribution area; wherein the content of the first and second substances,
the resource mapping information includes virtual resource information, hardware resource information and network element information corresponding to the home region.
It should be appreciated that the same set of MANO system architectures, as shown in FIG. 2, often have multiple OSSs deployed in different home regions. Through the above steps, the network device applying the resource management method of the embodiment of the present invention first determines the attribution areas of all OSS corresponding to the network device, and then generates and stores the resource mapping information from the determined attribution areas, and because the resource mapping information includes the virtual resource information, the hardware resource information, and the network element information corresponding to the attribution areas, the virtual resource information, the hardware resource information, and the network element information can be managed in the corresponding attribution areas, thereby improving the management effectiveness.
Considering the functions of each part in the MANO system architecture, NFVO is preferably a network device to which the resource management method of the embodiment of the present invention is applied. Of course, new network devices may be added to the MANO system architecture for the resource management method of the embodiments of the present invention.
Generally, the network element information includes, but is not limited to, an ID and a name of a MANO system network element VNF, the virtual resource information includes, but is not limited to, a general attribute and a usage status of the virtual machine VM, and the hardware resource information includes, but is not limited to, a hardware device model number and a vendor. Therefore, through the resource mapping information, the virtual resource information, the hardware resource information and the network element information corresponding to the home region can record the mapping relationship between the VNF, the VM and the hardware device in the same home region for the home region.
In addition, in this embodiment, optionally, after the step 102, the method further includes:
receiving a change notification message;
and adjusting the resource mapping information according to the change notification message.
Here, the change notification message is triggered when the resource mapping information is changed, and includes specific change contents, so that after receiving the change notification message, the stored resource mapping information can be further adjusted based on the change notification message, and the real-time performance of the resource mapping information can be ensured.
Wherein, the changing of the resource mapping information is, on one hand, a change of virtual resource and/or hardware resource occupation, and on the other hand, a change of a lifetime of the VNF, for example, creating a new virtual machine or performing a capacity expansion and reduction process on the virtual machine, and therefore, optionally, receiving a change notification message includes:
receiving a change notification message sent by a virtual resource manager under the condition that the occupation information of virtual resources and/or hardware resources is changed; alternatively, the first and second electrodes may be,
and receiving a change notification message sent by the virtual network function manager when the life cycle of the virtual network function changes.
Here, when the virtual resource and/or hardware resource occupation change, the VIM sends a change notification message to notify the NFVO (network device to which the resource management method of the embodiment of the present invention is applied) of the resource change, and the NFVO updates the resource mapping information according to the notification message; when the VNF lifecycle changes, the VNFM calls a VNF lifecycle change notification interface (change notification message) to notify the NFVO, and the NFVO updates the resource mapping information according to the notification message.
Taking the expansion and contraction as an example, an operator selects one VNFR on the NFVO + interface to perform the expansion and contraction operation, as shown in fig. 3, the specific steps are as follows:
1. NFVO + call C6: and the Scale VNF interface requests the VNFM to perform capacity expansion.
2. The VNFM creates a capacity expansion and contraction task and returns JobID to NFVO +.
3. The VNFM analyzes the resources required for this scalability.
4. VNFM call C6: and the GrantLifecycle interface requests NFVO + to perform resource authorization.
5. NFVO + checks whether there are enough resources in the VIM, if so, returns the same VIMID; if the resources are insufficient, authorization is denied.
6. The VNFM sends a request to create/delete virtual resources to NFVO +.
7. NFVO + sends a request to create/delete virtual resources to VIM.
8. The VIM detects the resource change and sends C7: pushVmChanges request (change notification message) to notify the VIM of the change of resources.
9. NFVO + returns a response to VIM.
10. NFVO + updates VM and hardware device (host) information in the resource mapping information.
11. VNFM sends C6 to NFVO +: a VNF policy change notification interface (change notification message) notifies a change of the VNF resource.
12. NFVO + returns a response to VNFM.
13. NFVO + updates VNF and VM information in the resource mapping information.
14. And the NFVO + obtains and stores the corresponding relation of the province (home region), the VNF, the VM and the host according to the notification messages of the VIM and the VNFM.
After the steps are carried out, an operator can see the expansion and contraction volume result on the NFVO + interface.
Further, in this embodiment, optionally, after generating and storing the resource mapping information in step 102, the method further includes:
receiving reported state information;
searching a target area according to the state information;
and sending the state information to an operation support system belonging to the target area according to the searched target area.
Wherein, receiving the reported state information comprises:
and receiving state information reported by a virtualized resource manager, wherein the state information comprises at least one of alarm information and performance information.
Here, the alarm information and the performance information are mainly for the VM or the host, and thus, by receiving the status information reported by the VIM, the status information of some VMs or hosts, such as the alarm information and/or the performance information, is known. In order to inform the corresponding OSS in time, after receiving the status information, the target area (i.e. the home area corresponding to the VM or the host) is searched according to the status information, and then the status information is sent to the OSS belonging to the target area.
Taking the virtual resource performance data management as an example, as shown in fig. 4, the specific steps are as follows:
1. NFVO + creates a performance metric subscription on VIM.
2. The VIM collects performance data for the virtual resources based on the performance measurement tasks.
3. And after receiving the performance data of the virtual resources, the VIM completes the management of the performance data of the virtual resources.
4. Meanwhile, the VIM reports the performance data of the virtual resources to the NFVO + through a performance measurement notification interface after the acquisition period is finished.
5. And after the NFVO + receives the performance data of the virtual resources, the management of the performance data of the virtual resources is completed.
6. And NFVO + inquires province information corresponding to the VM.
7. NFVO + synchronizes performance data of virtual resources to OSS serving provinces.
In summary, the resource management method according to the embodiment of the present invention first determines the home regions of all OSS corresponding to the resource management method, and then generates and stores the resource mapping information from the determined home regions, and because the resource mapping information includes the virtual resource information, the hardware resource information, and the network element information corresponding to the home regions, the resource management method can manage the virtual resource information, the hardware resource information, and the network element information corresponding to the home regions, thereby improving the effectiveness of management. And then, the resource mapping information can be updated in time aiming at the change notification, and the reported state information can be notified to the corresponding OSS through region query, so that the data sharing with the corresponding region OSS is realized.

And then, the resource mapping information can be updated in time aiming at the change notification, and the reported state information can be notified to the corresponding OSS through region query, so that the data sharing with the corresponding region OSS is realized.
