Virtual network function deployment method, device and system adopting NEC (network edge computing)

Abstract

The invention discloses a virtual network function deployment method, device and system adopting NEC (network edge computing) to reduce service delay and improve service quality. According to the method, a central VNFC (virtual network function component) receives first position information sent by a user terminal, then transmits a creation request message used for creating an edge VNFC to a VNFM (virtual network function manager) and creates the first position information carried in a first request message; the VNFM transmits the first request message used for creating a virtual machine or container of the edge VNFC to a VIM (virtualized infrastructure manager) after receiving the creation request message, and the first request message carries the first position information and a mirror image of the edge VNFC; the VIM determines an edge server on the basis of the first position information and deploys the edge VNFC on the edge server on the basis of the mirror image of the edge VNFC. Accordingly, the deployment position of an edge NFC (network function component) in an NEC scene approaches the position of a user, service delay is reduced, and the service quality is improved.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a virtual network function deployment method, device and system for network edge computing. Background technique [0002] Network Function Virtualization (NFV) technology migrates the functions of each network element used in the telecommunications network from the current dedicated hardware platform to a general-purpose Commercial-off-the-shelf (COTS) server, Virtualization is virtualized network function (virtualized network function, VNF). Theoretically speaking, NFV can be flexibly deployed on a unified infrastructure platform based on standard servers, storage devices, switches and other devices, and through virtualization technology, the resource pooling and virtualization of infrastructure hardware devices and the upper layer application Provide virtual resources to realize the decoupling of applications and hardware, so that each application can quickl...

Problems solved by technology

[0006] However, the current NFV technology is mainly aimed at centralized data center scenarios, and does not consider NEC scenarios. It cannot meet the above-mentioned requirements of NEC for NFV. In particular, the specific VNFC deployment location requirements are the closest to the needs of users. The current NFV deployment of VNFC is The analysis is based on the resource dimension, that is, VNFC is deployed on the server that meets its resource requirements and best meets the resource allocation strategy, and does not consider the closest user
