Title: VIRTUAL RESOURCE ALLOCATION METHOD, NFVO, AND SYSTEM
Abstract:
The present application relates to the field of communications, and discloses a virtual resource allocation method, an NFVO and a system for reducing a time delay of an NFV MANO operation. The virtual resource allocation method comprises: an NFVO receives from an OSS/BSS a first NS instantiation request comprising instruction information, a first VNF instantiation parameter and/or a first nested NS instantiation parameter, wherein the first VNF instantiation parameter is used to indicate an instantiation requirement for a VNF instance in a first NS instance, and the first nested NS instantiation parameter is used to indicate an instantiation requirement for a nested NS instance in the first NS instance; if the instruction information instructs real-time processing, then, according to NS instantiation limiting conditions and the first VNF instantiation parameter, a VNF instance is selected from a NS instance resource pool, and according to the NS instantiation limiting conditions and the first nested NS instantiation parameter, a nested NS instance is selected from the NS instance resource pool; and the selected VNF instances and/or nested NS instances are packaged and/or configured to perform instantiation on the first NS instance. Embodiments of the present application are used in 5G slice management scenarios.
