Problems solved by technology

Due to the limitation of server bandwidth, this download mode will seriously affect the download speed
[0007] The second is distributed, represented by BT and eMule. The main feature is that the resources are distributed on many personal terminal computers. This method avoids the impact of a single bandwidth on the download speed, but cannot guarantee the stability of the service.
[0014] With the rapid growth of Web information, users can obtain rich resources through search engines, but this type of search service has limitations: it is impossible for general search engines to parse and index all web pages on the Internet, and users need to call multiple search engines to obtain Satisfactory search results, reducing retrieval efficiency
However, both this type of search engine and the general search engine provide users with a large number of unordered web pages, and serve different users with the same mode, such versatility cannot meet the different individual needs of users

Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0063] see figure 1 , introduces the application environment-network system structure composition of the device for downloading Internet resources from multiple sources based on the meta search engine of the present invention. The system is divided into three parts:

[0064] Using the P2P overlay network established by the BT protocol, each node in the P2P network separately reserves the routing directory and shares its own resources, and each node is directly connected; each user in the overlay network can share resources. Users query and search for stable resources on the Internet, and then download links to obtain corresponding file data. The download of resources is divided into blocks to speed up resource acquisition. Its advantage is to combine the advanta...

Abstract

The invention discloses a multisource internet resource device based on meta search engine, and a method thereof. The device is provided with a user unit, an overlay network unit, a search unit and a downloading unit, all the units or software are deployed at the client terminal to complete all the downloading operation at the client terminal so as to weaken dependence of existing downloading devices on central server or multimedia search database, and fully utilize development of meta search engine to perform downloading application of internet. The device fully utilizes meta search engine of internet to position and discover file source address, performs multi-address search of the same resource to a target file, and perform parallel downloading and merging to the target resource by themultisource downloading technology, thus utilizing development of various search engines, improving accuracy of search results, and providing more fast and stable downloading service by utilizing themultisource downloading technology. Moreover, the resource addresses and search are set based on users, thus meeting personalized demand of users.

Description

technical field [0001] The present invention relates to a technology related to search engine and multi-source downloading, to be more precise, relates to a device and method for multi-source downloading of Internet resources based on personalized search of meta search engine, and belongs to the technical field of Internet resource downloading. Background technique [0002] Network download technology, also known as network file sharing technology, is the most widely used in the existing Internet. The first file sharing was mainly realized through Web technology, that is, after the shared files were put on the server to form a centralized file storage model, the client computer passed the hypertext transfer protocol HTTP (Hyper Text Transfer Protocol) and the text transfer protocol FTP (File Transfer Protocol) and other protocols download these files from the server, which is the so-called P2S (Peer to Server) structural mode from the user to the server. With the massive in...
