The implementation process of the embodiment of the present invention will be described in detail below.

As shown in Figure 3, including:

Step 31: VNFM initiates a resource request to VIM;

Step 34: After the VNFM obtains resources such as VMs from the VIM, it deploys various services and applications on the corresponding VMs. At the same time, the mapping relationship between each specific service component (module) VNFC and the ID of the VM to which it belongs is recorded.

Step 35: The VNFM notifies the EMS of the VNF information and resource information such as VMs deployed for the VNF network element;

Table 1

Step 37: When the service VNF network element fails, send service failure information to the EMS, and the service failure information carries the identifier of the first virtual machine to which the failed VNFC belongs. For example, the failed VNFC is VNFC-1, and the VNFC The identifier of the first virtual machine to which -1 belongs is VM1-ID.

Step 38: According to the business (application) failure situation, the EMS takes the VM ID as the main correlation factor, and obtains and displays the first NFVI resource information in the mapping relationship between the identifier of the virtual machine saved in advance and the NFVI resource information, so as to further determine the occurrence of the failure The path information of the physical host, so that users can quickly locate the problem according to the fault details.

Domain (Cloud)

data center

cluster

physical host

Virtual machine-------VM ID mapping-----VNF/VNFC

Example: As shown in Figure 1, VNFC-1 fails, VNFC-1 is deployed on VM1, and VM1 is virtualized from the physical machine Host1, which belongs to DC1. When Host1 fails, that is, Host1 is the source of the failure, EMS quickly uses VM1-ID as the main correlation factor to map and display resource information layer by layer, and quickly determine the physical host that has failed.
