Item or any combination. In the embodiment of the present invention, the description of the local resource capabilities and attributes provided by the NFVI server may be included in the "NFVI resources" database, and the NFVO may query or modify the database. Specifically, the NFVI server may provide a description of the local resource and the shared resource according to the resource type, and may include a local resource capability and an attribute description, a shared resource capability and an attribute description, and an NFVI resource status description, where the local resource capability and the attribute description may be Includes a description of the special acceleration hardware.

The resource can determine the VIM corresponding to the local resource, and further enable the NFVO to send the local resource reservation request to the VIM corresponding to the local resource.

可替换地， VNFD和 /或 VNF实例化参数中携带有本地资源的地址和 / 或本地资源对应的 VIM的地址。此时，步骤 404可以为： NFVO根据本地资源的地址和 /或本地资源对应的 VIM的地址 , 确定本地资源对应的 VIM。 Alternatively, the VNFD and/or VNF instantiation parameters carry the address of the local resource and/or Or the address of the VIM corresponding to the local resource.

The VIM identifier/address may be an IP address, a URL, or other identifier that can uniquely identify the VIM.

对于本发明实施例，通过在 VNFD中携带 VNF所需本地资源的具体地址或标识信息和 /或本地资源对应的 VIM标识 /地址信息，能够在实例化 VNF的过程中 , 避免通过 NFVO进行资源协调 , 从而可以使得 VNFM直接向对应的 VIM发送资源分配请求。 For the embodiment of the present invention, by carrying the specific address or identification information of the local resource required by the VNF in the VNFD and/or the VIM identification/address information corresponding to the local resource, the resource coordination through the NFVO can be avoided in the process of instantiating the VNF.

In the embodiment of the present invention, the distributed VNF can be simultaneously operated on the local resources and the shared resources, and the capacity can be expanded through the shared resources, thereby further improving the system performance. At the same time, the distributed VNF can run on local resources and shared resources at the same time, which can occur in local resources. In the event of a failure, allocate shared resources to the VNF so that the VNF can function properly.

进一步地，通过分布式 VNF同时运行在本地资源及共享资源上，能够为整个 NFVI提供较好的可伸缩性。具体地，当用户数量增多或者负载较大时，可以为分布式 VNF分配共享资源；当用户数量减少或者负载较低时，可以译放为分布式 VN F分配的共享资源。 Further, running the distributed VNF on both local resources and shared resources can provide better scalability for the entire NFVI. Specifically, when the number of users increases or the load is large, a shared resource may be allocated for the distributed VNF; when the number of users is reduced or the load is low, the shared resources allocated for the distributed VN F may be translated.

406、 NF VO接收 VIM发送的本地资源的预留结果。 406. The NF VO receives the reserved result of the local resource sent by the VIM.
