Copy management method and device in distributed storage system

Abstract

The invention discloses copy management method and device in a distributed storage system. The method comprises the following steps of: acquiring an intra-domain connecting parameter of a user and a system in each period; judging the following conditions through the connecting parameter: whether an experience weight coefficient indicating a connecting state of the user and a network is larger than a first threshold value or not, whether the request number of times to the copy is larger than a second threshold value or not and whether a health degree indicating the performance level of the copy is smaller than a third threshold value or not; and if the conditions are determined to all hold and the request number of times to the copy in a plurality of continuous periods before a current period is judged not to be zero, adding the copy into an affiliation domain of the user in the system. In the invention, considering from aspects of the experience weight coefficient, the request number of times to the copy, the health degree of the copy and the recent access quantity of the copy of the user, the load bearing capability of the system and the downloading experience of the user are both considered, and the problem of low downloading speed of the user or higher server load is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a copy management method and device in a distributed storage system. Background technique [0002] In the distributed storage system based on user experience, the distributed storage system is a storage system of each domain composed of multiple servers as nodes. The customer's download experience determines the number of copies, and the number of copies also affects the customer's experience. When a customer downloads a file, if there is no copy in the domain where the customer is located, the data will be obtained from nodes in other domains. Assuming that the transmission speed of the data between domains is very low and the transmission speed within the domain is high, it will affect the user's performance at this time. Download experience. Therefore, when the user experience in the domain is relatively low, it is necessary to consider whether to add a copy in the domain t...

Problems solved by technology

[0005] The main purpose of the present invention is to provide a copy management method and device in a distributed storage system, to at least solve the problem of users downloading due to the fact that there is no comprehensive measurement of whether to add copies from the server's load bearing capacity and the user's download experience. Issues with slow speeds or high server load
