Specifically, the security isolation policy involved in this implementation manner may include allocating a virtual resource to different sets or to different security isolation zones, and performing access control or security policy setting for the virtual resource in the sets or the isolation zones. When the virtual resource is allocated to the different sets or to the different security isolation zones, the resource is allocated according to one of or a combination of the following methods: setting an identifier of a set or an isolation zone to which a minimum unit of the virtual resource belongs; setting a security level; or setting, in the sets or the isolation zones, a catalog of virtual resources that need to be isolated, and specifying a number corresponding to a specific virtual resource or virtual machine, or a server on which the virtual resource or virtual machine is located; and in addition, that the virtual resource is allocated to a security isolation zone includes: the virtual resource is allocated to an isolation zone according to a geographic location at which the virtual resource is distributed, or a type of a user or a user group that accesses the virtual resource, or a type of an application or a service that uses the virtual resource, and/or a number of a user that uses the service.
In a process of performing access control on a set or a security isolation zone: a virtual resource in the set or the security isolation zone can be accessed only by using an access role, an access user level, or an access password that is configured for the set or the security isolation zone. It is not difficult to understand that, a virtual resource may need to be isolated to an extent due to a geographic location, a VIP requirement, service planning, or the like. Therefore, responding can be effectively preformed by using the security isolation policy in this implementation manner. In this implementation manner, the access role configured for the security isolation zones can be one of or a combination of the following virtual network elements: an NFVO, a VNF manager (VNFM), an operation and maintenance (O&M), or a VNF, a resource manager, a resource user, a resource querier, a visitor, or the like; and the access user level includes one of or a combination of the following: a very important person (VIP) level, a common user level, an operator level, or the like. Resources in an isolation zone have a same isolation identifier or isolation group identifier.

For example, in this implementation manner, clusters of different security levels or priorities may be set, and corresponding security levels or priorities may be configured; or virtual network resources may be set to manage multiple identities, where different identities have designated security levels, priorities, or passwords, so as to implement rights control on resource access operations of the identities; or a related VNF network element (that is, a VNF-ID set), VNFM-ID set, and VIM entity (a VM-ID set) that belong to the foregoing security group or priority group may be set; or a virtual resource access rights level, a security level of the VNFM or the NFVO, an access security password, or a security group level when the VNFM or the NFVO virtualizes the VNF may be set; or a label is set for a physical resource, the physical resource is allocated to a group, another management device or cloud system is prohibited from accessing a resource in the group, and only a user with a designated right or level is allowed to access the resource, so as to configure a policy of physical resource isolation; or a clock security policy is set, to allow a user with a designated security level to perform modification or reading.
It should be noted that, the security type policy controls use of a virtual resource, a security level or a password of a virtual resource occupying request, and a security level or an access password corresponding to a cluster to which a virtual resource requester (such as the VNFM, the NFVO, or the O&M) belongs, which all need to be compared with a lowest level limit or an access password corresponding to an access operation of virtual resources, to determine whether service requests and operations such as access to or use of these virtual resources are allowed.

In this implementation manner, the service or application priority policy includes setting a priority of an APP (application, network service application) to ensure resource use of a high-priority APP. When a resource is limited and a conflict occurs between various APPs for using the resource, an APP with a low priority is stopped or rejected, so as to ensure an APP with a high priority; or if an APP with a high priority needs to be expanded, a resource of an APP with a low priority may be released, so as to ensure that the APP with the high priority obtains a sufficient resource.

In this application, in an NFV deployment process, different virtual network elements can receive specific policy configuration information and perform separate configuration, so as to resolve a technical problem that in the prior art, when virtualized deployment is performed, a system needs to perform unified and coordinated processing on all virtual network elements, resulting in low efficiency and slow deployment. Specifically, in this application, configuration is performed for different virtual network elements in a targeted manner, so that a system resource is allocated and used more properly, and additionally a specific configuration catalog is refined by using policy configuration information, so that NFV deployment can be performed quickly and effectively, thereby increasing virtualization efficiency to a great extent, so as to quickly respond to and process a related service.
In the foregoing implementation manner, an NFV deployment location, or the like is optimized to a great extent. In this implementation manner, NFV deployment may be further optimized in combination with specifying a node location at which a policy is configured. For details, refer to
It should be noted that, as shown in
In this example, the sending module 11 of the NMS is configured to send, by using the Os-Nfvo interface, the policy configuration information to the NFVO to perform related configuration, where the NFVO forwards some or all of the policy configuration information to the VNFM and the VIM, where the NFVO configures the security isolation policy, the security type policy, the performance isolation policy, and the service or application priority policy by using a VNF-Catalog, an NS-Catalog (network service catalog), and an Instance-catalog; next, the VNFM receives the policy configuration information forwarded by the NFVO, and configures the deployment policy, the information reporting policy, the backup policy, the simulation program activation policy, and the go-online process policy of the VNF; and the VIM receives the policy configuration information forwarded by the NFVO, and configures the security isolation policy, the security type policy, the information reporting policy, and the backup policy.
Correspondingly, on a side of the virtual network element, the receiving module 20 of the NFVO is configured to receive, by using the Os-Nfvo interface, the policy configuration information to perform related configuration, and forward some or all of the policy configuration information to the VNFM and the VIM, where the NFVO configures the security isolation policy, the security type policy, the performance isolation policy, and the service or application priority policy by using the VNF-Catalog, the NS-Catalog, and the Instance-catalog; the VNFM receives the policy configuration information forwarded by the NFVO, and configures the deployment policy, the information reporting policy, the backup policy, the simulation program activation policy, and the go-online process policy of the VNF; and the VIM receives the policy configuration information forwarded by the NFVO, and configures the security isolation policy, the security type policy, the information reporting policy, and the backup policy.
