WEB-based distributed picture storage system

Abstract

The invention discloses a WEB-based distributed picture storage system. The WEB-based distributed picture storage system is characterized by comprising a client side, an address analysis server, a Web server cluster, a database interface mapping server and a picture server cluster; the client side is used for receiving a page, and automatically downloading and displaying corresponding pictures from different picture servers according to picture URL paths in the page; the address analysis server is used for monitoring the picture servers in the picture server cluster, and dynamically returning the optimal IP address to a caller; and the picture server cluster is used for storing all picture information of a website. By means of the WEB-based distributed picture storage system disclosed by the invention, the access speed of the website can be increased only by needing to increase little hardware cost; furthermore, the number of the picture servers and the picture storage directories can be dynamically adjusted according to requirements; and thus, the fact that the system has the expandability and the flexibility can be ensured.

Description

technical field [0001] The invention relates to the field of picture storage, in particular to a WEB-based picture distributed storage system. Background technique [0002] With the development of the Internet, many large and medium-sized websites have stored a large number of picture resources. When users visit these websites with extremely rich picture resources, the picture information in the webpage occupies a large part of the page data traffic, resulting in the following problems : [0003] 1. Due to the limitation of the client browser, it is impossible to download all the picture information in the page from one server at the same time; [0004] 2. Since the pictures are stored on the physical server, frequent I / O operations are required to access the pictures: therefore, when the number of concurrent users increases, the I / O operations will become the performance bottleneck of the entire system; [0005] 3. Due to the limitation of the operating system, the number...
