Data distribution method and device

Abstract

The embodiment of the invention discloses a data distribution method and device, which are applied to a data center in a data distribution network. The method comprises the following steps: receiving a part of data transmitted by a data center on a higher layer than the data center in the data distribution network specific to target data, and receiving the other part of data transmitted by a data center on the same layer as the data center in the data distribution network specific to the target data; combining the part of the data with the other part of data to generate the target data; judging whether the data center in the data distribution network is a bottommost-layer data center or not according to second information; if not, splitting the target data according to the second information; and transmitting the split part of data to a data center on a lower layer than the data center in the data distribution network according to a preset transmission rule in order that the bottommost-layer data center acquires the target data. Through application of the data distribution method and device, the transmission time of data can be shortened, and all the data centers can receive data transmitted by a highest-layer data center at the same time.

Description

technical field [0001] The present invention relates to the technical field of data distribution, in particular to a data distribution method and device. Background technique [0002] At present, there are many video websites at home and abroad that provide video viewing services. Video websites store a large amount of video content in data centers (IDC, Internet Data Centre), and these data centers in different places provide services to end users in different places. (The data center can be understood as a large physical computer room with many hosts in it, and each host provides services to the outside world). [0003] Large-scale video service providers store data on tens of thousands of machines in hundreds of data centers. These data can reach hundreds of millions of files, and hundreds of thousands of new data are added every day. When these new data are sent to the target machines in each data center, hundreds of millions of data distributions will be generated. T...

Problems solved by technology

In the above-mentioned distribution system, the time for target data to reach each data center is the sum of the time on the path from the data center to the highest-level data center, and the target data distribution speed is relatively slow

[0005] Also, see figure 1 , the target data must go through the Beijing-Tianjin-Shijiazhuang-Zhengzhou route before it can be sent from the Beijing data center to the Zhengzhou data center; There is a problem, which will cause the Zhengzhou data center and its corresponding lower-level data center to fail to receive the target data

see figure 2 , the target data must go through the Beijing-Tianjin-Zhengzhou route before it can be sent from the Beijing data center to the Zhengzhou data center; The lower data center cannot receive the target data

Therefore, in the existing distribution network, if there is a point of failure in the network, some data centers will not be able to receive the target data
