Embodiment Construction
[0083] In order to facilitate the understanding of the embodiments of the present application, the following elements are firstly introduced here to introduce the embodiments of the present application.
[0084] A virtualization container (virtualization container) is a part of a computing node and is used to provide an isolated virtualized computing environment. A typical example of a virtualization container is a virtual machine. A virtual machine (Virtual Machine, VM) refers to a virtual device simulated on a physical device by virtual machine software. For applications running in virtual machines, these virtual machines work just like real physical devices. Operating systems and applications can be installed on virtual machines, and virtual machines can also access network resources.
[0085] A virtualized network function (Virtualized Network Function, VNF), also called a virtualized network element, corresponds to a physical network function in a traditional non-virtuali...

The embodiment of the present application discloses a method and device for virtual network function resource management. The method includes: the virtual network function management VNFM device sends a preprocessing request message to the network element management EM device, and the preprocessing request message is used to request the The EM device performs resource shrinkage preprocessing on the virtual network function VNF instance, wherein the resource shrinkage preprocessing includes migrating services carried by virtualized containers that need to perform resource shrinkage preprocessing; the VNFM device determines the After the EM device completes the resource shrinking preprocessing, the VNFM device performs resource shrinking processing on the VNF instance. The method and device provided by the embodiments of the present application can avoid damage to the services carried by the virtualized container corresponding to the VNF instance when performing resource shrinkage by performing migration processing on the pre-processed and carried services of the virtualized container.
Description
technical field [0001] The present application relates to the communication field, and in particular to a method and device for virtual network function resource management. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) technology can implement some network functions on general-purpose hardware in software. For example, in a telecommunications network, NFV technology can be used to implement some telecommunications Network functions, so as to realize the rapid and efficient deployment of network services. [0003] The NFV technology realizes expansion and contraction of network elements through elastic scaling (scaling), that is, dynamically allocates or reclaims related resources for virtualized network functions (Virtualized Network Function, VNF) according to requirements. At present, when performing scaling in processing, the virtual network function manager directly deletes the virtual machine after determining the...
