And the public cloud management platform receives first mirror image chain information from the terminal through the IDV management platform, circularly searches in a local mirror image chain list according to the first mirror image chain information, and acquires mirror image data elements which are lacked in the local mirror image chain and mirror image data elements with different sizes from the IDV management platform according to the mirror image sequence of a father and a son to update the local mirror image if the same mirror image exists. And if the same mirror image does not exist, sequentially uploading the whole mirror image chain according to the sequence of father and son, and combining the whole mirror image chain into a new mirror image chain in the common cloud management platform. The first mirror image chain information is mirror image chain information to be uploaded by the terminal and comprises a mirror image chain unique identifier, a mirror image data element size and a mirror image data element parent-child relationship. And circularly searching in the local mirror chain list according to the first mirror chain information, wherein the circular searching is carried out according to the mirror chain unique identifier in the first mirror chain information to determine whether the mirror chain exists.

(2) The terminal image acquisition process comprises the following steps.
As shown in fig. 3, the terminal image obtaining process of the present invention is actually a process of downloading images by various terminals under the lan model, and when a terminal needs to obtain a corresponding image, the terminal is defined as a terminal to be obtained with an image, which may be one or multiple terminals. In the invention, a public cloud management platform sends second mirror image chain information to a mirror image terminal to be acquired, the mirror image terminal to be acquired obtains mirror image data elements needing to be downloaded by comparing the second mirror image chain information, and sends a data source list acquisition request to the public cloud management platform so as to acquire the mirror image data elements.
In the embodiment of the invention, before the terminal acquires the mirror image, the public cloud management platform divides each mirror image data element in the local mirror image chain into a plurality of data blocks, and obtains the unique identifier of each data block based on a hash algorithm. And the public cloud management platform sends second mirror image chain information to each terminal, wherein the second mirror image chain information comprises a mirror image chain unique identifier, a mirror image data element size and a mirror image data element parent-child relationship. The terminals are defined as mirror image terminals to be acquired, after the mirror image terminals to be acquired receive second mirror image chain information, mirror image data elements to be downloaded are obtained by comparing mirror image chain unique identifications of the second mirror image chain information, the mirror image data elements are sent to a public cloud management platform to obtain positioning information of positions of data blocks of the mirror image data elements, the public cloud management platform forms a data source list according to the positioning information and sends the data source list to the mirror image terminals to be acquired, the mirror image terminals to be acquired obtain the data source list of the mirror image data elements to be downloaded based on the data source list, so that corresponding data blocks are downloaded, and all data block pairs are subjected to data block recombination after downloading is completed to form the mirror image data elements.

In the process, the transmission is carried out according to the sequence algorithm that the mirror parent is in front of the child. Meanwhile, in the terminal mirror image acquisition process, the invention sets the terminal mirror image acquisition mode under 4 scenes. The 4 modes are based on the situation of judging the local mirror image of the terminal when the mirror image terminal to be obtained obtains the mirror image data element needing to be downloaded by comparing the second mirror image chain information.
Judging whether the mirror image information associated with the second mirror image chain information exists in the local basic mirror image through the mirror image terminal to be acquired to acquire the mirror image data element to be downloaded, specifically:
if the complete mirror image of the mirror image information does not exist, the public cloud management platform takes the chain mirror image as a mirror image data element to be downloaded through the IDV management platform and transmits the mirror image data element to the mirror image terminal to be acquired according to the sequence of the father before the son after the son;
if the root mirror image does not exist, the public cloud management platform takes the chain mirror image as a mirror image data element to be downloaded through the IDV management platform and transmits the mirror image data element to the mirror image terminal to be acquired according to the sequence of the father before the son after the son, the mirror image terminal to be acquired automatically eliminates the existing root mirror image, and all node mirror images are acquired according to the sequence of the father before the son after the son.
If the root mirror image and the partial node mirror image exist, the public cloud management platform takes the chain mirror image as a mirror image data element to be downloaded through the IDV management platform and transmits the mirror image data element to the mirror image terminal to be acquired according to the sequence of the father before and the son after, the mirror image terminal to be acquired automatically eliminates the existing root mirror image and the node mirror image, and the missing node mirror image is acquired according to the sequence of the father before and the son after.
If the root mirror image exists but the node mirror images of the root mirror image conflict, the public cloud management platform takes the chain mirror image as a mirror image data element needing to be downloaded through the IDV management platform and transmits the mirror image data element to the mirror image terminal to be obtained according to the sequence of the father, the son and the back, the mirror image terminal to be obtained finds out the conflicting node mirror image and deletes the conflicting node mirror image, and the transmitted node mirror image is obtained again according to the sequence of the father, the son and the back.
The mirror image management system under the IDV mode provided by the invention specifically expounds a three-layer architecture model of the system, and realizes effective transmission of mirror images across local area networks. In the mirror image chain management, for each time of updating contents of mirror images, an incremental mirror image needs to be added on the basis of the original mirror image and the parent-child relationship needs to be stored in a database to form a chain mirror image, and each chain mirror image has a corresponding unique identifier. In the mirror image transmission process, the server side sends the whole chain type mirror image file and the content to the terminal, the terminal confirms whether the same mirror image exists according to the unique identification of the mirror image, and downloads the missing incremental mirror image according to the parent-child relationship of the mirror image. Therefore, the problems of overlarge mirror image, incomplete transmission and overlong transmission time are avoided.
The invention aims to build a public cloud management platform, add an IDV management platform into the public cloud management platform, manage the IDV management platform below the public cloud management platform through the public cloud management platform, and manage the terminals below the public cloud management platform by using the IDV management platform, thereby forming a three-layer architecture of the system. Through a three-layer system architecture, terminals under different local area networks can be uniformly brought into a public cloud management platform for management, in cross-local area network mirror image transmission, terminal mirror images under the public cloud management platform are operated by the public cloud management platform, uploaded to the public cloud management platform through an IDV (integrated digital video) management platform, and mirror image information is distributed to the terminals under the different local area networks, so that the problem of cross-local area network mirror image transmission is solved.
