Abstract

The invention provides a cloud storage service system and a cloud storage service method. A task scheduler receives a request from a client and establishes a corresponding task. According to the task type of the task, a server is selected for the task through combining with a secondary random selection algorithm based on a task load queue size, thus the cloud storage service is provided via the server. According to the cloud storage service system and method, the flow scheduling problem of the computer cloud storage system is solved, the maximal load of the server is significantly reduced, and thereby the load balancing between the servers, the high throughput of the system and the relatively low task response delay are achieved.

Description

technical field [0001] The invention relates to the technical field of network storage, in particular to a cloud storage service system and method. Background technique [0002] The personal cloud storage service system consists of storage nodes, block servers, task schedulers and related network environments. The user's request on the client side will first reach the task scheduler, and the task scheduler allocates a block server for the task according to a certain scheduling strategy. Fetching, so as to achieve the purpose of responding to requests and load balancing. [0003] In the existing technology, the most widely used is the round-robin scheduling algorithm (Round-Robin), which distributes external requests to the block servers in the cluster in turn. It assumes that all servers have the same processing capacity and treats each server equally. server, regardless of the actual connection status and system load of the server. This algorithm is only effective when t...
