Data cache method and system

Abstract

The invention relates to a data cache method which comprises the following steps that a client receives a transmission data packet and calculates a feature code of the transmission data packet; the client judges whether the transmission data packet exists in a cache according to the feature code, and if so, the client acquires and upload a feature code sequence corresponding to a generation sequence of the feature code; a server acquires an original data packet and calculates a feature code of the original data packet; the server judges whether the feature code of the original data packet belongs to the received feature code sequence, if so, the server acquires conformation information corresponding to the feature code and returns the conformation information; and the client acquires the transmission data packet from the cache and forwards the transmission data packet according to the received confirmation information. Moreover, the invention also provides a data cache system. By the data cache method and the data cache system, the cache can be arranged only on the single edge of the client, so that the utilization rate of stored resources can be improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a data caching method and system. Background technique [0002] At present, more and more enterprises and institutions use the network to conduct office and conduct business, and the quality requirements for the network are also getting higher and higher. The ever-increasing amount of data has led to higher and higher investment costs for enterprises and institutions in network facilities. However, according to statistics, about 70% of the data volume on the network is redundant, so if this part of redundant data volume can be reduced, network bandwidth can be greatly improved, network investment costs can be reduced, and office efficiency can be improved. [0003] In addition to using traditional compression algorithms to compress data, the WAN optimization systems of major WAN optimization vendors often use data caching to reduce traffic. Usually, the same data is stored at ...

Problems solved by technology

[0004] However, in the bilateral cache method in the traditional technology, both the server and the client optimization system need to cache data, which wastes a lot of storage resources and makes the utilization of storage resources not high.
