Problems solved by technology

[0008] In the prior art, since each UUID is a unique completely random number (such as a random character string including 36 characters), the similarity between each UUID is low, and since each UUID is compressed, each The lower the similarity of UUID is, the lower the compression rate is, thus, the compression rate of each UUID in the prior art is lower, which leads to the fact that each compressed UUID will still occupy more network resources during transmission. , resulting in slower data transfer rates

Embodiment Construction

[0024] In order to solve the problem in the prior art that the compression rate of each UUID is low when each UUID is compressed at the same time because each UUID is a random number, in the embodiment of this application, when the sending end generates the UUID corresponding to each data before sending each data , UUID can be generated according to compressible fields and non-compressible fields, wherein the non-compressible fields of each UUID are different, and the compressible fields of each UUID are the same. Since the non-compressible fields of each UUID are different, the uniqueness of each UUID can be effectively guaranteed, and since the compressible fields of each UUID are the same, the compressible fields of each UUID can be compressed into one field, so Therefore, the compression rate of each compressed UUID can be greatly reduced, thereby reducing the network resources occupied by each compressed UUID during transmission, and thus effectively increasing the data tr...

Abstract

The invention discloses a data transmission method and a data transmission device, which are used for increasing transmission rate of data containing UUID. The data transmission method comprises the steps of: determining pieces of data to be transmitted by a transmitting end; generating a universally unique identifier UUID corresponding to each piece of data, wherein each UUID comprises a compressible field and an uncompressible field, the compressible fields of the UUID are identical, and the uncompressible fields of the UUID are different from one another; compressing the UUID; and transmitting the data containing the compressed UUID to a receiving end. According to the data transmission method and the data transmission device, since the compressible fields of the UUID are identical, and the compressed UUID occupies few network resources during the transmission process, thereby being capable of effectively improving the data transmission rate.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data transmission method and device. Background technique [0002] In a communication system, data storage devices often perform data synchronization processing on the data stored by themselves, that is, data backup, out of consideration for data security and importance. For example, the sending end (such as a terminal or network device) that stores data sends the data stored by itself to the receiving end through the formation of data packets according to the data synchronization request of the receiving end (such as a network device or terminal). This process is data synchronization process. [0003] In order to ensure the consistency of the synchronized data, before sending each data, the sender will generate a Universally Unique Identifier (UUID) for the data that can uniquely identify the data, and then send the UUID together with the data to the receiving en...
