Abstract

The invention discloses a data cleaning method for edge cloud migration of a self-organizing network. The data cleaning method specifically comprises a repeated data deletion technology and a semantic difference elimination technology. The repeated data deletion comprises the following specific steps of: (1) selecting the size of the granularity of a comparison data block; (2) using a FUSE library as a middle layer so as to discover a disk and a memory part which are modified in the process of creating and starting the virtual machine, then redirecting writing to a corresponding overlay file when a virtual disk or a memory snapshot is written every time, and indicating that the block is changed through a bitmap mark; (3) obtaining a list of the modified disk and memory blocks, and calculating the changed blocks by using an SHA algorithm to obtain hash values; (4) obtaining a group of block lists with the same change through a plurality of comparison methods; the semantic difference elimination technology comprises disk semantic difference and memory semantic difference. According to the method, a whole set of practical data cleaning technology is provided for rapid migration of the cloud computing platform in a bandwidth-limited wireless network environment, the data transmission quantity in the migration process can be remarkably compressed, migration delay is reduced, and meanwhile, the data compression and transmission efficiency is higher than that of traditional cloud computing migration.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data cleaning method for edge cloud migration of an ad hoc network. Background technique [0002] 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 edge infrastructure. Form an elastic cloud platform with comprehensive computing, network, storage, and security capabilities at the edge, and form an end-to-end technical architecture of "cloud, edge, and terminal collaboration" with the central cloud and IoT terminals. Computing, intelligent data analysis and other tasks are processed at the edge, reducing response delay, reducing cloud pressure, reducing bandwidth costs, and providing cloud services such as network-wide scheduling and computing power distribution. [0003] Since the edge cloud platform is deployed at the edge of the network, the performanc...
