Method and device for allocating virtual resources in network function virtualization nfv network

Abstract

Embodiments of the present invention relate to a method and a device for allocating virtual resources in a network function virtualization (NFV) network. The method comprises that a virtual machine infrastructure management (VIM) receives a plurality of virtual resource request messages, each virtual resource request message includes identification information, and the identification information represents at least one virtual resource use unit; the VIM according to preset rules, according to the identification information to determine the priority of each virtual resource request message; the VIM performs resource allocation according to the priority of each virtual resource request message. In the method and device for allocating virtual resources in the NFV network of the embodiment of the present invention, the VIM allocates resources for virtual resource request messages in order of priority according to the priority, so that the efficiency and flexibility of resource use can be improved when resource requests are processed concurrently , improve the stability and reliability of the system, and respond faster and more effectively to certain emergency situations.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and a device for allocating virtual resources in a network function virtualization NFV network. Background technique [0002] With the development of cloud technology, virtualization technology, as the basic technology of cloud computing, has been widely used in the field of enterprise data centers and large-scale cluster computing. [0003] Network Functions Virtualization ("NFV" for short) technology virtualizes a computer into multiple virtual logical computers, namely virtual machines (Virtual Machine, "VM" for short). A virtual machine generally uses a virtual network card, a virtual switch, and a server physical network port connected to a switch in the chassis or a top-of-rack switch to communicate with the outside of the server. [0004] NFV technology borrows information technology (Information Technology, referred to as: IT) virtualization technology, so that...
