Problems solved by technology
Since the communication between node servers of different IDCs needs to occupy the dedicated line bandwidth connected to the IDC, and the number of node servers in many IDCs is relatively large, and the update frequency of system software or application software is relatively fast, so the traditional method is between multiple IDCs. A large amount of private line bandwidth is required when distributing data between
[0006] In addition, in the traditional method, once an error occurs on the data source server, it may cause the node server that has not downloaded the source file to be unable to download the source file. Therefore, the traditional method has a low fault tolerance rate

Embodiment Construction
[0028] Such as figure 1 As shown, in one embodiment, a data distribution method of a network data center includes the following steps:
[0029] Step S20, at least one node server of the network data center downloads the source file from the data source server.
[0030] In an embodiment, the node server that downloads the source file from the data source server may be a plurality of node servers that belong to different IDCs. After the node server has downloaded the source file, other node servers (including other node servers belonging to the same IDC and other node servers belonging to different IDCs) that have not yet downloaded the source file can download the source file. Specifically, the data source server may be included in a certain IDC, and is a server in the IDC that stores source files.
[0031] In one embodiment, before step S20, the source file may be uploaded to the data source server.
[0032] In one embodiment, before step S20, the above-mentioned data distr...

The invention discloses a data distribution method and system for a network data center. The method comprises the following steps: at least one node server of the network data center downloading a source file from a data source server; a download management server storing the identification of a node server which already downloads the source file; a node server, which does not download the source file, of the network data center querying from the download management server the identification of the node server which already downloads the source file; and the node server which does not download the source file establishing download connection with a queried node server which already downloads the source file and downloading the source file from the node server which already downloads the source file. By using the method, some node servers in a network data center download a source file from a data source server, and other node servers download the source file from node servers which already download the source file so that it is unnecessary for all the node servers to download the source file from the data source server, thus occupation of special-line bandwidth of the network data center can be reduced.
Description
【Technical field】 [0001] The invention relates to network technology, in particular to a data distribution method and system for a network data center. 【Background technique】 [0002] The Internet Data Center (IDC) is an Internet-based network base that includes multiple servers. Each server is a node of IDC for centralized collection, storage, processing and sending of data, so the server can also be called a node server. The node servers of the IDC are connected to each other to form a local area network. [0003] With the rapid development of the Internet, the business of Internet companies is also developing rapidly, and the number of IDC servers used to support the business is increasing day by day. An IDC deploys as many as tens of thousands or even hundreds of thousands of servers. In order to meet the needs of business expansion and take into account the factors of geographical distribution, multiple IDCs are often deployed in different regions to support services....
