Description

System for refreshing content using real time search ranking and method

The present invention relates to a contents delivery network (CDN) service, and more particularly, to a content refresh system and method utilizing real-time search information ranking on a CDN.

The international network that forms the interworking of various local and wide area networks (WAN) around the world is called the Internet. The Internet can be infinitely extended by interworking through communication media, and supports the smooth exchange of information by connecting networks with each other. In recent years, subscriber networks between network operators and web users, called ISPs (Internet Service Providers), have been replaced by asymmetric or symmetrical digital lines, and as the bandwidth available to users increases, there is an increasing demand for content services. More content services, in turn, require advancement of communication networks. A content user who wants to provide a content service accesses a content server provided by a content provider and downloads desired content. In this case, the network is overloaded, causing bottlenecks as the network moves between ISP networks, which causes delays or frequent disconnections.

Various efforts have been made to solve the above problems and to improve speed on the Internet. For example, an ISP (Internet Service Provider) may expand a backbone network called a back-bone. However, the purpose is to smoothly handle traffic within individual networks, which is not effective due to the increase in data transmission rate, which is more than doubled.

As a second example, an improvement in the speed of the Internet can be achieved through the improvement of the subscriber network section from the backbone network called Last-Mile to the home or business. However, it is difficult to expect an improvement in the speed of the Internet because investment has not been made in the link between the backbone network and the backbone network called Middel-Mile or the backbone network and the subscriber network.

An alternative to solve the problem is a content delivery network (CDN). The CDN does not improve the connection between the backbone network and the subscriber network by expanding the physical network, but rather by distributing the data traffic, that is, the bottleneck, using the proxy server, which is the main point of the Internet network.

The technical problem of the present invention devised to improve the above problems is for the purpose of efficient management of network resources.

When the client 10 requests a web page (URL request), the request is sent to the proxy server 30. The proxy server 30 receives the web page from the web server 70 by requesting the web page from the web server 70 of the URL. Thereafter, the proxy server 30 transmits the received web page to the client 10. Through the above process, the process for the client 10 to request the search information of FIGS. 4 and 5 may be completed.

First, referring to FIG. 4, the process of collecting the optional content is performed. The client 10 requests the search information to the ranking unit 40 of the proxy server 30 through the received web page (S401). The search information request may be performed by inputting terms corresponding to the search information request.

The ranking unit 40 receiving the search information request in S401 collects the number of times for the search information request for a predetermined time to determine the search information rank, and extracts the search information that exceeds the threshold value among the number of search information requests (S402). ).

The ranking unit 40 generates the selective content request signal Sig_Select for the extracted search information and transmits the selective content request signal Sig_Select to the web server 70 (S403).

The web server 70 transmits the matched selective content Data_Select to the proxy server 30 according to the selective content request signal Sig_Select (S404).

The proxy server 30 stores the optional content Data_Select in the proxy server DB 31 (S405).

Meanwhile, referring to FIG. 5, a process in which the optional content is provided will be described. After the client 10 receives a web page from the web server 70 by his request, the client 10 may proxy the server 30. Request search information with. The search information request is transmitted to the ranking unit 40 of the proxy server 30 as described above, and also to the control unit 33 of the proxy server 43 (S501).

The controller 33 determines whether the content that matches the search information request performed by the client 10 in S501 is included in the already stored optional content Data_Select (S502). More specifically, it is determined whether the proxy server DB 31 of the proxy server 30 includes the optional content Data_Select matching the search information request.

As a result of the determination in S502, when the proxy server 30 includes the content matching the search information request performed in S501 in the optional content Data_Select, the controller 33 may match the matched content among the optional content Data_Select to the client 10. Transfer to (S503). In this case, since the client is directly received from the proxy server 30 without passing through the web server 70, the digital server may be efficiently managed from the standpoint of the web server 70.

On the other hand, if there is no matching content in the proxy server DB 31 as a result of the determination, the control unit 33 transmits a request for the content corresponding to the search information to the web server 70 (S504).

The web server 70 receiving the request for the content corresponding to the search information in S504 delivers the content corresponding to the search information to the client 10 through the proxy server 30 (S505).

The invention can also be embodied as computer readable code on a computer readable recording medium. Computer-readable recording media include all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which are also implemented in the form of carrier waves (eg, transmission over the Internet).
