Data access method and uniform resource locator (URL) server

Abstract

The embodiment of the invention discloses a data access method and a uniform resource locator (URL) server used for improving the reliability, performance and extendibility of a network file system. The data access method comprises that: a first URL server receives a data access request carrying a URL address transmitted by a user; if the first URL server determines that the resource pointed by the URL address is stored in the first URL server, corresponding read-write operation is executed on the resource according to the data access request; and if the resource is not stored in the first URL server, a second URL server where the resource pointed by the URL address is positioned is queried, and the data access request is forwarded to the second URL server, so that the second URL server executes corresponding read-write operation on the resource according to the data access request. The embodiment of the invention also provides a URL server. The data access method and the URL server can effectively improve the reliability, the performance, and the extendibility of the network file system.

Description

technical field [0001] The invention relates to the communication field, in particular to a data access method and a uniform resource locator server. Background technique [0002] With the development of large-scale network storage, while accessing storage through the network is becoming more and more common, it also puts forward higher requirements for performance. The most common way to access data on the Internet is through a browser. The Uniform Resource Locator (URL, Uniform Resource Locator) similar to "http: / / www.myweb.com / html_2 / 1.html" is the most Commonly used representation. [0003] A network file storage method in the prior art is traditional network distributed storage. Several data storage servers are connected to a metadata server, and the metadata server is connected to an interface server. The interface server can provide users with Interface, through which the user can access data through the interface server. After receiving the user's access request, t...

Problems solved by technology

[0004] However, in the above-mentioned technical solutions, the metadata is stored centrally in the metadata server. Once the metadata server fails, the entire network file system will be directly paralyzed;

[0005] Secondly, the processing of requests sent by users and the processing of network files are completed by the interface server, which puts forward high performance requirements for the interface server, which may make the interface server become the bottleneck of the network file system, thereby affecting the network file system performance, and when the interface server fails, the entire network file system will also be directly paralyzed
