An indexing device and method for resource storage in a CDN system

Abstract

The present invention provides an indexing device and method for resource storage in a CDN system. The device includes: a name extraction unit for acquiring and extracting a file name in a Uniform Resource Locator URL; a name judging unit for judging the file Whether the complexity of the name reaches the preset complexity, if so, use the file name as the generation factor; otherwise, use the URL as the generation factor; the key value generation unit is used to generate the key value according to the generation factor through a preset algorithm; An index building unit, configured to create an index table of the storage location of the key value and the corresponding resource in the cache library. Therefore, the present invention can establish an index with a high degree of correspondence between resources and key values ​​in the CDN system, and provide index services for resource requests and resource update processes, thereby reducing cache redundancy and file false hit rates in the CDN system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an indexing device and method for resource storage in a CDN system. Background technique [0002] With the popularization and development of the Internet and network applications, the emergence of a large number of websites and the consequent huge amount of visits make network services overwhelmed, and content distribution network (CDN) came into being. CDN is a new type of network content service system that provides content distribution and services based on content access and application efficiency requirements, quality requirements, content order, and customer bandwidth restrictions. It represents a network-based high-quality, high-efficiency , A network application service model with a clear network order. [0003] When the CDN is facing LAN users, the CDN system will be deployed at the exit of the LAN network in a bypass. When a user requests a certain resource, the...

Problems solved by technology

For example, website A and website B provide the download of a certain resource at the same time, and the key values ​​corresponding to the different URLs of the resources obtained by users on websites A and B are also different, but in fact the resources corresponding to the two key values ​​are the same, so the index appears The resources corresponding to multiple key values ​​in the table will be repeated, resulting in large-scale redundant resources stored in the cache module

[0006] It can be seen that because the existing technology cannot establish an index with a high degree of correspondence between resources and key values ​​in the CDN system, problems such as large-scale cache redundancy and file mishits appear in the CDN system
