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 for distributed multi-cloud storage. The system comprises: a proxy server serving as a user uploading and downloading relay to optimize data transmission, feeding back the link bandwidth of a cloud storage node to a scheduling controller, and migrating the data to cloud storage nodes in other regions; a scheduling controller processing the user operation request in an online queuing manner based on a preset priority, selecting a node set with optimal access performance according to the link bandwidth of the cloud storage node, and adaptively adjusting the number of node proxy servers; and a local manager used for sending the user request operation to the scheduling controller, and interacting with the returned node set with the optimal performance according to a preset data storage mode to complete data transmission. According to the system, general and complete data transmission support can be provided for most cloud storageservice upper-layer application programs, optimization of data transmission performance and efficient utilization of resources are considered at the same time, and user experience and resource expenditure of application service providers can be effectively balanced.

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...
