Problems solved by technology

[0004] However, in actual implementation, the data sent by the sending end device to the receiving end device is generally the same as the data cached by the WAN accelerator installed on the receiving end device side. Therefore, the above-mentioned WAN acceleration technology can achieve a limited effect of saving bandwidth resources.

Embodiment Construction

[0041] A data block refers to a collection of a part of data to be transmitted. The sizes of different data blocks can be the same or different.

[0042] The fingerprint of a data block refers to identification information used to mark the data block obtained based on all feature information of the data block. Different data blocks have different fingerprints.

[0043] The similar fingerprint of a data block refers to the identification information used to mark the data block obtained based on the specific feature information of the data block. For example, a certain data block is the character string "78905", if the specific characteristic information is the characteristic information of the character at the second position, then the similar fingerprint of the data block is the characteristic information of "8"; The characteristic information of the characters at 5 positions, then the similar fingerprint of the data block is the characteristic information of "5". The simil...

Abstract

The application discloses a data processing method and device, which relate to the field of computer technology and help to save bandwidth resources. The method includes: the first device calculates the similar fingerprint of the data to be transmitted, the similar fingerprint of the data to be transmitted includes the similar fingerprint of the first data block; the first device sends the similar fingerprint of the data to be transmitted to the second device, the similar fingerprint of the data to be transmitted The fingerprint is used to find whether a reference data block similar to the data to be transmitted is stored in the second device; the first device receives the fingerprint of the reference data block sent by the second device; the fingerprint of the reference data block includes the fingerprint of the first reference data block; The similar fingerprint of the first reference data block is the same as the similar fingerprint of the first data block; the first device finds the first reference data block in the first device according to the fingerprint of the first reference data block; the first device finds the first reference data block based on the fingerprint of the reference data block The fingerprint sends data to the second device; the data includes difference data between the first reference data block and the first data block.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] With the continuous advancement of the cloud computing industry, the cloud infrastructure of mainstream manufacturers, such as cloud computing centers, cloud disaster recovery centers, and edge clouds, has begun to be widely deployed. These infrastructures form a complex wide area network (wide area network, WAN) network topology, and data transmission between these infrastructures needs to spend a lot of WAN bandwidth resources. Under limited bandwidth conditions, WAN acceleration technology is usually used to save bandwidth. [0003] The WAN acceleration technology is to install a dedicated device at both ends of the WAN link, that is, a WAN accelerator (accelerator, ACC). The WAN accelerator caches part or all of the transmitted data and uses data deduplication technology to reduce the amount of d...
