Problems solved by technology

In this wireless ad-hoc network, the edge cloud platforms are mobile and connected through a wireless network with limited bandwidth. The connection is not stable, which brings great difficulties to the transmission of virtual machine image files, because usually Under normal circumstances, the relatively streamlined Linux client virtual machine image file is about 400MB, and the image file based on the Windows operating system is usually larger than 2GB. Such a virtual machine image file cannot be directly migrated in a wireless environment; in a wireless ad hoc network The edge cloud platform running in the cloud cannot save a large number of custom virtual machine images (snapshots) like the traditional cloud; on the other hand, the mobile application is complex and changeable, and the state of the user virtual machine is time-varying, so the static method cannot guarantee the service
To sum up, the existing data center cloud computing platform migration technology, or 5G MEC technology, does not consider the mobile scene between data centers, and the data processing technology used generally does not consider high compression rate and network reliability. Therefore, it is difficult to adapt to wireless ad hoc network applications with unstable connections and limited bandwidth, let alone provide high-quality and low-latency cloud services
Therefore, the present invention aims to solve the problem of realizing fast edge cloud migration in a wireless ad hoc network environment with limited bandwidth and unstable connection

Abstract

The invention provides an edge cloud migration method and system suitable for a wireless self-organizing network environment, and the method comprises the steps: generating a virtual machine coverage file of a virtual machine disk and a memory snapshot, transmitting the virtual machine coverage file, synthesizing the virtual machine coverage file with a basic virtual machine mirror image file stored in an edge cloud, and generating a starting virtual machine. And meanwhile, by deleting redundant repeated data in a virtual machine coverage file, eliminating semantic difference between an application layer and a virtual machine bottom layer and a parallel transmission synthesis mode, the size of the virtual machine coverage file is further reduced, the migration efficiency is improved, the network load is remarkably reduced, and low-delay and high-reliability migration in the wireless ad hoc network is realized.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to an edge cloud migration method and system suitable for a wireless ad hoc network environment. Background technique [0002] Cloud computing is a mode of supplying and managing scalable, elastic, and shared physical and virtual resource pools in an on-demand self-service manner, and providing network access, providing users with low-latency cloud computing services is the development of cloud computing an important direction. Edge cloud is a technology based on cloud computing technology that provides cloud computing capabilities for network edge nodes. It is a cloud computing platform built on the edge infrastructure, forming an elastic cloud platform with comprehensive computing, network, storage, security and other capabilities at the edge, and forming a "three-body collaboration of cloud, edge and terminal" with the central cloud and IoT terminals The end-to-end technical arch...
