Classified data transmission method and system

Abstract

The invention discloses a classified data transmission method, which comprises that: a client transmits a data transmission request to a server, wherein the transmission request carries the class information of data to be transmitted by the client; after receiving the data transmission request, the server records the class information of the data to be transmitted by the client, and calculates allowed transmission speed according to the class information and preset class-information-based bandwidth utilization rules; the client and the server perform data transmission at the transmission speed; and after the data transmission is finished, the server deletes the recorded class information to be transmitted by the client. The invention also discloses a classified data transmission system. By the method and the system, the classifying transmission of the data can be realized, and key data can be transmitted preferably, thereby reducing the transmission time of the key data an improving the data security.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a classification data transmission method and system. Background technique [0002] At present, with the improvement of our country's informatization level, more and more data content is generated by enterprises and institutions. It has become more and more important to protect the data content generated in the process of work by establishing dedicated servers and adopting technologies such as backup and disaster recovery. an application field. [0003] figure 1 It is a schematic diagram of the existing typical backup and disaster recovery system structure, such as figure 1 As shown, the backup / disaster recovery server (for convenience of description, the backup / disaster recovery server is referred to as the server hereinafter) is connected to multiple clients through the network. When backing up data, the client sends the data to the server for backup. When restorin...

Problems solved by technology

[0007] Therefore, 80% of non-critical data occupies a large amount of bandwidth, causing delays in transmission of critical data will often occur

For example, in the newspaper office in the above example, the network administrator set the financial data to start backing up after get off work at 17:00 every day, and the reporter also set his picture data to start backing up after get off work at 17:00. At this time, a large amount of picture data and financial data will be backed up at the same time Transmission to the server through the network, assuming that it takes 5 hours for the image data to be completely transmitted, and only 30 minutes for the financial data, but in the existing technology, the data is treated equally during the transmission process, so when data queuing and network congestion occur In some cases, the financial data may take up to 5 hours to complete the final transmission, that is, the existing technology objectively prolongs the transmission time of key financial data, which undoubtedly increases backup failures, data damage or loss and other accidents Chances of occurrence, making critical data less secure
