Embodiment Construction

[0034] In the present invention, an edge cloud composed of corresponding server nodes is set in the cloud to form a cloud storage system structure based on digital fountain codes composed of "core cloud", "edge cloud" and user terminals, such as figure 2 shown. By setting storage nodes between the core cloud storage center and the terminal, the communication traffic at the exit of the core cloud is reduced, thereby reducing the delay and ensuring the QoS of cloud storage.

[0035] Core cloud: With powerful storage capabilities, supported by the edge cloud, it cooperates with each other to provide users with transparent cloud storage services quickly and elastically. The core cloud is a cloud storage service center composed of server clusters with powerful storage capabilities. Users use various storage services provided by the core cloud according to their own needs.

[0036] Edge cloud: It is composed of server nodes distributed in different networks and regions, providing ...

Abstract

The invention discloses a digital fountain code based cloud storage system structure and a service providing method. By means of the system structure and the service providing method, the quality of service (QoS) of a cloud storage is effectively guaranteed. Edge clouds are deployed on different networks and in different regions, and the digital fountain code based cloud storage system structure is formed by a core cloud, the edge clouds, a terminal user and a digital fountain code coding and decoding layer. According to the system structure, services of common data, frequently-used data by a user and the like are distributed on the edge clouds of the networks or the regions where the terminal user is located, and the core cloud and the edge clouds cooperate to transparently provide a cloud storage service for the user. On the above basis, the service providing method specific to the digital fountain code based cloud storage system structure, the cooperating method of the core cloud and the edge clouds, and a user data migration method are provided. According to the digital fountain code based cloud storage system structure and the service providing method, most of network flow in the cloud storage is limited to local terminal users, the flow of a backbone network is reduced, the problem of the dependence of a centralized type cloud storage mode on the network bandwidth, the time delay and the like is effectively avoided, and the QoS of the cloud storage is guaranteed.

Description

technical field [0001] The invention relates to a cloud storage architecture based on a digital fountain code. By introducing the concepts of edge cloud and digital fountain code encoding and decoding layers, the dependence of cloud storage on network bandwidth is reduced, and the QoS of cloud storage is improved. The invention relates to information technology fields such as cloud storage, digital fountain codes, distributed storage, and computer networks. Background technique [0002] Cloud Storage (Cloud Storage) is a more reasonable and effective service provision and operation model in network storage. In this model, various storage services that are traditionally located locally will be stored in the cloud by a large and centralized storage model. service superseded. In cloud storage, users can conveniently and transparently use various storage resources provided by cloud storage service providers on demand. These storage resources can be quickly provided and obtaine...
