Virtual resource allocation method, nfvo and system

Abstract

The present application discloses a virtual resource allocation method, NFVO and system, which relate to the communication field and are used to reduce the time delay of NFV MANO operation. The virtual resource allocation method includes: NFVO receives a first NS instantiation request from OSS / BSS, which includes indication information, first VNF ​​instantiation parameters and / or first nested NS instantiation parameters, and the first VNF ​​instantiation parameters are used for Indicates the instantiation requirements of the VNF instance in the first NS instance, and the first nested NS instantiation parameter is used to indicate the instantiation requirements of the nested NS instances in the first NS instance; when the indication information indicates real-time processing, according to the NS Select the VNF instance from the NS instance resource pool according to the instantiation restriction condition and the first VNF ​​instantiation parameter, and select the nested NS instance from the NS instance resource pool according to the NS instantiation restriction condition and the first nested NS instantiation parameter; The selected VNF instances and / or nested NS instances are assembled and / or configured to instantiate the first NS instance. The embodiments of this application are applied to 5G slice management scenarios.

Description

technical field [0001] The present application relates to the communication field, and in particular to a virtual resource allocation method, NFVO and system. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) is a telecom network operator, by referring to the virtualization technology in the field of Information Technology (IT), to integrate some telecom network functions into software and Hardware decoupling enables rapid and efficient deployment of Network Services (NS), and at the same time achieves the operational goal of saving investment and operating costs. [0003] In the environment of NFV, NS is a complete function that presents the characteristics of network connection composed of a set of virtualized network functions (Virtualized Network Functions, VNF) and / or a set of nested network services (Nested NS). NS is determined by its functional and behavioral characteristics, and implements a set of life cycle manag...
