Embodiment Construction

[0019] This software-defined network distributed image search engine framework includes the following steps:

[0020] 1) Construct a set of distributed memory object cache system, as a proxy server see attached figure 2 , for reducing database load in dynamic systems;

[0021] 2) Through the link of METAFILE, realize the extraction and indexing of URL and histogram and establish the mapping between URL and histogram;

[0022] 3) To build a highly available load balancing server cluster, see attachment image 3 , storing indexed URLs and histograms;

[0023] 4) Retrieve the URL pointing to the address of the image format file by using the keyword or uploading the image format file containing the keyword;

[0024] 5) Carry out the accurate retrieval of histogram again to retrieval result, through the mapping of histogram and URL, determine the URL pointing to the picture format file address, obtain picture format file;

[0025] 6) The backbone network can run on OpenFlow, a...

Abstract

The invention discloses a network distributed image search engine frame based on the software definition. The frame comprises a user interface, a search ranking, a cache crawling and a server cluster, wherein backbone networks can run in OpenFlow, and are distributed in date centers all over the world through network links, and the utilization rate of a wide-area circuit is increased.

Description

technical field [0001] The invention relates to a software-defined network distributed picture search engine framework Background technique [0002] A web crawler, also known as a web spider or a web robot, is a program that automatically extracts web pages. It downloads web pages from the Internet and is an important part of search engines. Web crawlers use the standard HTTP protocol to traverse the Internet information space based on hyperlinks and Web document retrieval methods. [0003] At present, search engines only search for text, and cannot search multimedia files such as music, pictures, and videos. The main reasons are that the amount of multimedia data is too large; how to index multimedia files; and then retrieve processed multimedia files. There are a large number of multimedia files on the Internet now, especially with the rise of social networking sites and multimedia sharing, it is necessary to accurately retrieve multimedia files. [0004] There are thous...
