Problems solved by technology
The key to the above method is to find one or more suitable intermediate nodes. However, in actual operation, existing data centers are deployed according to business needs, basically without considering the time zone of the data center. Therefore, the appropriate There are usually few intermediate nodes, which reduces the data transmission efficiency of data scheduling between data centers; in addition, because the amount of data transmitted each time between intermediate nodes is usually large, there are few intermediate nodes and less idle storage In the case of , it is difficult to complete the data transmission within the overlapping idle time window interval, which also reduces the success rate of data scheduling between data centers

The invention discloses a dispatching method and system for data between data centers. The dispatching method includes that a CSP management platform gathers intermediate node information and sends to a control node, and the control node stores the intermediate node information provided by the CSP management platform; the CSP management platform which needs to transmit data calculates a data transmission path according to the intermediate node information and data server in the current network, records the use information of each intermediate node used in the path and sends the use information to the control node; the control node marks the intermediate nodes as used intermediate nodes. On the one hand, each cloud service provider initiatively supplies usable nodes thereof to serve as intermediate nodes, so that the number of the proper intermediate nodes is greatly increased, and the data transmission efficiency of the data dispatching between the data centers is improved; on the other hand, along with the increase of the intermediate node, the free storage space is increased, the transfer for transmitting large amount of data between the intermediate nodes is guaranteed, and the data dispatching success rate is improved between the data centers.
Description
technical field [0001] The invention relates to cloud computing technology, in particular to a data scheduling method and system between data centers. Background technique [0002] With the vigorous development of Internet business and cloud computing, network business is increasingly transferred to data centers with a large number of servers and storage clusters. At the same time, in order to provide a better user experience, cloud service providers (CSP, Cloud Service Provider) have built a large number of distributed, cross-regional data centers, and user access requests are processed by the data center closest to the user. Distributed deployment of data centers speeds up user access, but at the same time increases the difficulty of management. Data centers often need to transmit a large amount of information, including information synchronization, data backup, and data migration. Existing research results show that the data flow between data centers is basically the sam...
