Embodiment Construction

[0035] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] The system framework of the present invention, such as figure 1As shown, the cloud storage service provider purchases server resources from the IaaS provider according to the business needs, and the server nodes are organized into a distributed overlay network (Overlay Network) according to the peer-to-peer relationship. User data is distributed and stored among the server nodes according to the DHT mechanism. superior. Through the unified service access interface, users can easily log in to the system and use cloud storage services.

[0037] A kind of resource dynamic allocation method of the cloud storage system based on DHT mechanism of the present invention, comprises the following steps:

[0038] Step 1) According to the end user's access to the cloud storage system, the cloud storage system performs real-time monitoring of use...

Abstract

The invention discloses a cloud storage system resource dynamic allocation method based on a DHT mechanism. The method includes the following steps that first, according to the conditions for a terminal user to have access to a cloud storage system, the user access request volume, the access request state, the access performance and server state data in the system are monitored in real time by the cloud storage system, and monitoring data are acquired; second, the data acquired in the first step in real time are analyzed, and whether resource supply reaches the target performance level or not in the running process of the system is judged; third, a resource allocation model is established, and resources are allocated according to the resource allocation model. According to the method, the service performance level and the resource usage conditions are analyzed through a queuing network, so that the service performance of a server is guaranteed, and resource usage cost is reduced.

Description

technical field [0001] The invention relates to the field of cloud computing and distributed storage, in particular to a method for dynamically allocating resources of a cloud storage system based on a DHT mechanism. Background technique [0002] Cloud computing is a computing model that uses the Internet to access shared resource pools anytime, anywhere, on demand, and conveniently. It connects a large number of nodes and network devices to form one or several large-scale data centers, and provides various levels of services based on the data center, including infrastructure services IaaS, platform services PaaS and software services SaaS , each level of service corresponds to the role of a cloud service provider. Cloud storage service is an upper-layer service. Service providers purchase resources located in data centers from IaaS providers to build cloud storage systems. For example, cloud storage service provider Dropbox builds systems on top of Amazon data centers. En...
