Detailed Description

The present invention will be described in further detail with reference to specific embodiments in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The invention provides a cloud desktop migration method, which comprises the following steps:

s1, a cloud desktop control system receives user login information and a migration instruction input by a user;

s2, the cloud desktop control system transmits the appointed cloud file to a cloud server interacted with the cloud desktop control system for storage according to a migration instruction input by a user;

in step S2, the cloud end server stores the designated cloud file in the following manner:

the transmission equipment and the client equipment acquire Token from the service server, verify identity through Token and make effective signature;

further, the token is a digitized representation. Each token is associated with a unique digital ID by which the model distinguishes between different tokens. During training, the model learns the way text is mapped to these digital IDs to be able to encode and decode new text.

The specific process is as follows:

this process may be implemented in a mapping manner known as a vocabulary. The vocabulary is a mapping table built in advance by the model, mapping each possible token to a unique number ID. For example, for English words, a vocabulary may contain words such as "hello", "world", "chat", etc., and each word is assigned a unique numeric ID. After the input text is split into tokens, the model looks up the corresponding IDs of each token in the vocabulary and uses those IDs to represent the input text.

In particular, the manner in which text is split into tokens may vary depending on the task and model requirements. One common way is to segment the text by spaces or punctuation marks, with each word being a token. However, for some languages, such as chinese, word segmentation is a more complex process that requires consideration of the relationship between words and characters.

Once the input text is converted to a sequence of digital IDs, the model can treat it as input. These digital IDs may be represented in vector form, for example using one-hot coding or more common word embedding representation methods. Word embedding represents each token as a continuous vector, where each dimension represents some semantic feature.

In processing the token, the model may operate on a token-by-token basis or may obtain more context information by considering relationships between the tokens;

note that, the token limits the input length for the following reasons:

computing resources: processing long sequences requires more computing resources and memory. As the input length increases, the amount of computation of the model increases. In order to ensure that the model can complete the calculation in a reasonable time, it is necessary to set a maximum length limit.

Memory limitations: the memory resources of the model are limited. Loading long sequences completely into memory may exceed the available memory capacity. By limiting the input length, it is ensured that the model can accommodate memory limitations and perform calculations efficiently.

Training effect: long sequences typically introduce more noise and redundant information while increasing the complexity of the model. This may result in the training process becoming more difficult and inefficient. By limiting the input length, training can be more centralized and efficient, and the performance of the model can be improved;

the transmission equipment performs slicing pretreatment on the data to generate a slicing file, and uploads the slicing file to the cloud storage server with a signature;

the service server stores information into a service database after uploading the slice file to the cloud storage server;

the client device carries signature and request information to carry out authentication and authentication to the service server, after the authentication and authentication of the client device are passed, service finds corresponding information from the service database according to the request information to generate Url, the Url is sent to the client device, and the client device pulls and plays cloud storage slice files to the cloud storage server according to the Url;

s3, the cloud desktop control system determines a forward target position according to a migration instruction input by a user, and detects a storage space of the position;

specifically, the storage space for detecting the position is specifically:

acquiring a data table and a log corresponding to the data table, which are related to vector data to be detected, in a space database, and analyzing the log by adopting a log analysis tool to obtain a first data table before data operation and a second data table after data operation of the data table; obtaining a first data object before data operation according to the first data table, and obtaining a second data object after data operation according to the second data table;

carrying out space superposition analysis on the first data object and the second data object, and if one data object is obtained after merging, the data operation does not cause data boundary change and space position change of vector data to be detected; otherwise, the data operation causes the data boundary change or the space position change of the vector data to be detected, so that the storage space is calculated;

if the first data object and the second data object are subjected to space superposition analysis, and at least two data objects are obtained after the space superposition analysis, comparing the coordinate sequences of the first data object and the second data object one by one, and judging whether the deviation of the point corresponding to the coordinate sequence of the first data object and the point corresponding to the coordinate sequence of the corresponding second data object in the transverse quantity is consistent or not and whether the deviation of the point corresponding to the coordinate sequence of the corresponding second data object in the longitudinal quantity is consistent or not; if the deviation of the point corresponding to the coordinate sequence of the first data object and the deviation of the point corresponding to the coordinate sequence of the corresponding second data object in the horizontal vector are consistent and the deviation of the point corresponding to the coordinate sequence of the corresponding second data object in the vertical vector is also consistent, judging that the data operation causes the spatial position change of the vector data to be detected, and does not cause the data boundary change of the vector data to be detected;

if the deviation of the point corresponding to the coordinate sequence of the first data object and the deviation of the point corresponding to the coordinate sequence of the corresponding second data object on the horizontal vector are inconsistent or the deviation of the point corresponding to the coordinate sequence of the corresponding second data object on the vertical vector are inconsistent, judging that the data operation causes the data boundary change and the space position change of the vector data to be detected;

s4, the cloud desktop control system calculates the size of the cloud file to be migrated in the user migration instruction, and compares the size with the storage space of the migration target position;

the cloud desktop control system calculates the size of the cloud file to be migrated in the user migration instruction as follows:

determining a target file, wherein the target file comprises a plurality of data blocks, the target file is a file of a source file, the source file also comprises a first file, the first file comprises a plurality of data blocks, the first file is a file with creation time before the creation time of the target file and closest to the creation time of the target file, and the first file is not deleted;
