Virtual network loading method and device

Abstract

The embodiment of the invention provides a virtual network loading method and device. The virtual network loading method comprises the following steps: a NFVO (Network Functions Virtualization Orchestrator) receives a NSD (Network Service Descriptor) sent from a first network entity; the NFVO selects a candidate VIM (Virtualised Infrastructure Manager) which can distribute virtual resources to a VNF (Virtualization Network Function) when the VNF is deployed according to a restricted condition in the NSD and a restricted condition in a VNFD (Virtualised Infrastructure Manager Descriptor) in a VNF catalogue; the NFVO sends the VM (Virtual Machine) image file of the stored VNF or a URL (Uniform Resource Locator) corresponding to the VM image file of the VNF to the candidate VIM; the NFVO notifies a NS (Network Service) catalogue to be added into the NSD; and the NFVO sends a NSD loading success notification message to the first network entity. The virtual network loading method and device provided by the embodiment of the invention is used for optimizing a virtual network loading flow, and saves network transmission resources and storage space in the VIM in a loading process.

Description

technical field [0001] The embodiments of the present invention relate to network technologies, and in particular to a virtual network loading method and device. Background technique [0002] On October 23, 2012, 13 large operators in the telecommunications industry released a white paper on Network Function Virtualization (NFV) and announced the establishment of the NFV Industry Standards Organization (Industry Standard Group, referred to as NFV) at the European Telecommunications Standards Institute (ETSI). ISG). The founding members of NFVISG include American Telephone & Telegraph (ATT for short), Deutsche Telekom (DT for short), British Telecom (BT for short), Telefonica for short, France Telecom (FT for short), etc. company. At present, nearly a hundred companies around the world have become members of the NFVISG organization. [0003] The purpose of operators establishing NFVISG is to define the requirements of operators' network function virtualization and related ...

Problems solved by technology

[0007] However, since the size of the VNFpackage is on the order of gigabytes, and the VMimage file accounts for the majority, uploading the VMimage file to multiple possible VIMs during the VNFOn-boarding process may cause the VMimage file to be uploaded To an unrelated VIM, which may cause unnecessary operations and waste of network transmission resources and storage space on the VIM during the loading process
