Embodiment

[0095] In the following, the present invention will be further elaborated by implementing the designed load balancing algorithm and building a simulation test environment for the designed algorithm through coding.

[0096] In the prototype implementation of the algorithm designed by the present invention, the public cloud storage environment is constructed based on the Eucalyptus framework version 3.2 of open source Linux, and the Walrus controller is used as the storage control module, and the original deduplication component of the Eucalyptus framework is used as the data deduplication module. Heavy modules. The load balancing algorithm proposed by the present invention is implemented as a functional module of the public cloud storage environment - a load balancing module, which can be easily compiled and added to the public cloud storage environment. Wherein, the coordination agent submodule obtains information such as their IP address, storage capacity, used space, remaini...

Abstract

The invention discloses a cloud storage based load balancing calculating method. When a file write-in request is received, a load balancing module in a central coordinator distributes input file blocks in a mode of balancing all the public cloud storage node loads, wherein the load balancing module consists of three sub-modules including a coordinator agent sub-module, a node positioning sub-module and a load balancing sub-module. The load balancing calculating method comprises the following steps: (1) acquiring the state information of the storage nodes; (2) calculating the storage nodes with relatively light loads and recording the IP addresses; (3) calculating the size of loads to be moved and moving data; (4) repeating the steps (1-3) until the load of the storage nodes is balanced. According to the invention, the quantitative approaches of the load states of the public cloud storage nodes are given, and the core algorithm of the load balancing of the public cloud storage cluster is clear, and the cloud storage based load balancing calculating method has the attribute characteristics of practicability and high efficiency.

Description

technical field [0001] The invention relates to a computing method, in particular to a cloud storage-based load balancing computing method. Background technique [0002] Public cloud storage is a cluster built using commercial machines and providing data storage services for public users. A public cloud storage cluster includes a group of heterogeneously configured storage nodes S={Si / iε(1,..,n)} and a commercial machine acting as a central coordinator (Central Coordinator, CC). The central coordinator is the interactive interface between public cloud storage clusters and users, and coordinates the storage resources of all public cloud storage clusters, usually including three components: storage control module, data deduplication module and load balancing module, such as figure 1 shown. [0003] When the storage resources of all commercial machines are integrated, the public cloud storage cluster can provide services through the Internet. Wherein, various commercial mach...
