Embodiment approach

[0027] The present invention proposes a data transmission scheduling system oriented to distributed multi-cloud storage, and its overall structure diagram is as follows figure 1 As shown, including: Proxy Server, Scheduling Controller and Local Manager; where:

[0028] The proxy server is deployed adjacent to the cloud storage nodes in this area, and acts as a user upload and download relay to optimize data transmission, estimate the link bandwidth of the cloud storage node online and feed it back to the scheduling controller, and migrate data to other areas when free cloud storage node;

[0029] The scheduling controller processes user operation requests online based on preset priorities, periodically collects the link bandwidth of cloud storage nodes, selects a set of nodes with the best access performance to provide to the client requesting the current operation, and adaptively adjusts the number of nodes Number of proxy servers;

[0030] The local manager monitors the us...

Abstract

The invention provides a data transmission scheduling system oriented to distributed multi-cloud storage. The system includes: the proxy server acts as a user upload and download relay to optimize data transmission, feeds back the link bandwidth of the cloud storage node to the scheduling controller, and migrates the data to other regional cloud storage nodes; the scheduling controller is online based on the preset priority Queue up and process user operation requests, select the node set with the best access performance according to the link bandwidth of cloud storage nodes, and adaptively adjust the number of node proxy servers; the local manager is used to send user request operations to the scheduling controller, and according to the preset data storage method Interact with the returned set of nodes with the best performance to complete the data transfer. The present invention can provide general and complete data transmission support for most cloud storage service upper-level applications, and it can optimize data transmission performance and efficiently utilize resources at the same time, and can effectively balance user experience and resource expenditure of application service providers.

Description

technical field [0001] The invention belongs to the technical field of cloud storage, and in particular relates to a data transmission scheduling system oriented to distributed multi-cloud storage. Background technique [0002] Compared with traditional network storage, cloud storage service has the advantages of easy access, low maintenance cost, and high scalability. In recent years, it has been used by more and more enterprise applications and individual users. At present, popular cloud service providers such as Amazon AWS, Microsoft Azure, Google Cloud Platform, and Alibaba Cloud have deployed globally distributed data centers to provide quality-guaranteed online data storage and content distribution services to users in different regions. On this basis, the cloud storage service application uses the distributed nodes of the public cloud platform to build a content distribution network (CDN) to provide users with low-latency data access. For example, personal clouds suc...
