RESOURCE CONFIGURATION METHOD, VIRTUALIZED NETWORK FUNCTION MANAGER AND NETWORK ELEMENT MANAGEMENT SYSTEM

摘要

This application relates to the field of communications technologies, and in particular, to a virtualization resource management technology in Network Functions Virtualization. In a resource configuration method, after obtaining a performance parameter that reflects a running status of a VNF instance, a VNFM determines, based on a mapping relationship between the performance parameter and a deployment flavor in a descriptor file corresponding to the VNF instance, a target deployment flavor that is suitable to be configured for the VNF instance in the running status, and performs resource configuration for the VNF instance based on a currently configured deployment flavor of the VNF instance and the target deployment flavor. The solutions provided in this application can ensure a normal running status of the VNF instance.
