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...

AI Technical Summary

Problems solved by technology

[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 of picture files that can be stored in a directory is also limited: with the continuous increase of picture resources, how to effectively manage and maintain pictures is also a problem

[0006] For a small number of large-scale website systems, due to their own strong financial and human resources, NFS, CDN, Lighttpd, reverse proxy, load balancing and other technologies can be used to improve user access speed, but these technologies require huge funds to support
