Problems solved by technology

At present, the mainstream compression technology is the LZO (Lempel-Ziv-Oberhumer) data compression algorithm and its deformation compression algorithm. Since the LZO data compression algorithm can only perform data compression in a small data area, the compression ratio is not high, which is very important for reducing redundancy. The effect of the data is limited; in addition, it has no effect on the compressed data, so it cannot effectively solve the problem

Embodiment Construction

[0035] According to the statistics of existing technology, in the data transmission between peer-to-peer networks, about 70% of the data is redundant data. Theoretically, there is no need for 70% of redundant data to be transmitted between peer-to-peer networks. Therefore, if the 70% redundant data can be reduced as much as possible, the speed of data transmission can be greatly improved. The present invention is based on this idea, and replaces data segments with tags composed of eigenvalues ​​in order, and saves the position of eigenvalues ​​in the data dictionary in the hash bucket, and only transmits the tags and hash during data transmission. Buckets, reducing the transmission of redundant data as much as possible.

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Abstract

The invention discloses a method for accelerating data transmission. The method includes: setting a data dictionary at the data sending end and the receiving end; Eigenvalues, the obtained eigenvalues ​​are combined into labels according to the order in which the corresponding fields appear in the data segment, and the position of the eigenvalues ​​in the data dictionary is saved in the hash bucket, and the labels and hash buckets are sent to the data receiving end; data receiving The terminal sequentially reads the position of the feature value stored in the hash bucket in the data dictionary, queries the data dictionary, and obtains the data corresponding to the feature value according to the label and the position of the feature value in the data dictionary, according to the order of the feature value in the label. Data segment restoration. The invention also discloses a system for accelerating data transmission. By adopting the technical scheme of the invention, the efficiency of data transmission can be greatly improved, the consumption of bandwidth by data transmission can be reduced, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to data transmission technology in the Internet, in particular to a method and system for accelerating data transmission. Background technique [0002] With the popularity of the network, the data carried in the network is growing in a blowout manner, which seriously affects the speed of data transmission. In order to solve this problem, there are several solutions: one method is to continuously upgrade the bandwidth, but upgrading the bandwidth requires expensive fees, which is not a fundamental solution; [0003] Another way is to compress the data. At present, the mainstream compression technology is the LZO (Lempel-Ziv-Oberhumer) data compression algorithm and its deformation compression algorithm. Since the LZO data compression algorithm can only perform data compression in a small data area, the compression ratio is not high, which is very important for reducing redundancy. The effect of the data is limited; in addition, i...
