KR20020070655A - A operation method of terabyte data service with media domain name server - Google Patents

Abstract

PURPOSE: A method for operating a high capacity data service through MDNS(Media Domain Name Server) is provided to restart a service immediately through the other media server in case of the service interruption caused by an error of the media server, and to increase the stability and reliability of the service by a user always using the latest domain name data. CONSTITUTION: A user enters a domain of the desired web server(3) and calls an MDNS server(2) managing the domain name data of the web server or media server(4). The MDNS analyzes the requested domain name data and sends the call data to the web server, which also analyzes the call data and sends the image or text data to the user. In case of a moving picture, the web server calls again the MDNS, which analyzes the domain name requested by the web server and sends the call data to the relevant media server. Also, the media server analyzes the call data and sends the moving picture data to the user. Finally, the user plays the moving picture data through a proper media player.

Description

Operation method of large data service through media domain name server {A operation method of terabyte data service with media domain name server}

The present invention relates to a data service operation method through a media server that provides a large amount of data such as video data, and more particularly, to provide a domain name information to the media server, and to operate the MDNS to manage this service to another media server. At the time of transfer, even if the IP (Internet Protocol) of the media server is changed, by maintaining the domain name of the existing media server, the service can be continued without modifying the location information (URL: Uniform Resource Locator) of the media server and the user can use the user terminal. The present invention relates to a method of operating a large-capacity data service that provides stable data service by registering MDNS information in a media server and immediately using changed IP information of a media server.

In general, as shown in FIG. 4, in order to provide a video data service, a web server 3 and a media server 4 should be operated. The URL, which is a location address of the video data in the web server, is linked to an image or text, By inserting, it is designed to be played through the media player according to the call of the user 1.

In this case, the URL of the video data is set using the media server's IP mms: //211.233.38.210/vod/demo.asf, ftp://211.233.38.210/vod/demo.asf, http://211.233.38.210/vod You connect in the same way as /demo.asf.

In the above case, in the event of a failure of the media server, in order to continue the service, the administrator selects one of the methods of providing the service after moving the video data to another media server or providing the service after replacing it with another media server.

In case of resuming the service after moving the data to another media server, as the IP of the media server is changed, it is necessary to change the URLs of all the video data in the web server (3) and restore the failed media server (4). In case of restarting the video data, the URL of the video data should be changed again according to the media server IP change.

When the failed media server 4 is replaced with another media server to restart the service, there is no change of the IP of the media server 4, but it takes a lot of time before setting up the server and moving the video data.

As shown in Fig. 5, in order for the user 1 to access the server 3 on the Internet with a domain name, the user 1 must go through a DNS 5 for changing the domain name into an IP address. In general, all user terminals that can access the Internet use DNS, and the number of DNS distributed in the Internet network is difficult to guess. In addition, DNS provides service for domain name information that it does not have through other DNS and information delivery.

In this case, if the domain name information is changed in one DNS, it takes 12 to 72 hours for the changed information to be reflected in all the DNS. During this time, users can change the domain name information before and after the change. Acceptance causes confusion in service usage.

Therefore, the present invention can immediately resume the service through another media server even if the service is interrupted due to the failure of the media server, server check, or other causes to solve the above problems, the user always has the latest domain name information The purpose is to provide a way to increase the stability and reliability of the service by making it available.

Mass data service operating method according to an embodiment of the present invention to achieve the above object, MDNS (2) for managing the domain name information of the user terminal 1 and the media server set to use the MDNS (2), video And a web server (3) for providing URL information of images and texts, a media server (4) for providing a large amount of data such as video data, and a data automatic distribution program for backing up data on the media server to other media servers. It is characterized by.

1 is a system configuration diagram applying a video data service operating method according to an exemplary embodiment of the present invention, wherein a user 1 having a terminal installed with an application capable of accessing the Internet or playing back video data or other data has an address of a web browser. By entering the domain of the web server to be connected to the window, the MDNS server 2 which manages domain name information such as the web server 3 and the media server 4 is called.

MDNS (2) analyzes the domain name information requested by the user (1) and delivers the call information to the web server (3), the web server (3) analyzes the call information to store the image stored in the web server (3) Or send the text information to the user (1).

The user 1 calls the necessary information according to the information transmission of the web server 3, the web server 3 calls the MDNS (2) again in the case of a video having a domain name, the MDNS (2) Web The domain name requested by the server 3 is analyzed and the call information is transmitted to the corresponding media server 4.

The media server 4 analyzes the call information and transmits the video data to the user 1, and the user 1 plays the video data through a suitable media player.

2 is a flowchart illustrating a method of operating an administrator according to an embodiment of the present invention, a process of assigning a domain name to a media server 100, a process of registering and changing domain name information to MDNS 110, and data to a media server. A process 120 for setting an automatic distributed program, a process for determining whether a failure occurs in the media server 130, and a process 110 for changing and setting the IP of the corresponding domain name in the MDNS when a failure occurs.

For example, you can assign a domain name to a domain you own corresponding to the IP address of the media server. 211.233.38.210 is vod.vodhosting.com, and 211.233.38.211 is vod1.vodhosting.com, 211.233.38.212. Defines the server's IP address and domain name using vod2.vodhosting.com.

The service manager installs an automatic data distribution program in each media server, specifies a media server and folder where original data is stored, a media server and folder to back up original data, and sets an automatic backup cycle and time (120).

3 is a flow chart of the operation method of FIG. 1 and is described in the user's service use environment.

First, the user 1 registers 10 the IP address of the MDNS 2 (for example, using 211.233.39.134) in the DNS configuration information so that the MDNS becomes the first priority in the network configuration environment setting of the terminal.

A user enters domain name information such as "http://www.vodhosting.com" into a web browser address window such as an Explorer to access a web server, and calls MDSN 2 (20).

MDSN (2) checks whether there is information of "www.vodhosting.com" among the domain name information of MDNS, and if there is information, converts the domain name into "211.233.38.210" and delivers the calling information to the web server (30). )do.

If there is no domain name information, check whether there is information on the corresponding domain name in the upper DNS, and if there is information, convert the domain name to "211.233.38.210" (40) and deliver the call information to the web server (50). do. If there is no domain name information, a domain name error message is output (92).

The web server 3 analyzes (60) the call information of the user 1 according to the information transfer of the MDSN 30 or the DNS 40, and " mms: //vod.vodhosting.com/vod/demo.asf" In the case of the video data with domain name information of the media server as shown above, MDNS (2) is called again, and the image or text or other data stored in the web server (3) without the domain name information is transmitted to the user (91). .

The MDNS 2 changes the domain name of the media server 4 to an IP address according to the call of the web server 3 (70), and calls the video data from the media server (80). The media server 4 transmits the called video data to the user 1.

If the server fails, the service provider changes the IP address of the domain name of vod.vodhosting.com to 211.233.38.211. Since the video data of 211.233.38.210 server is backed up equally in 211.233.38.211 server by the setting of data automatic distribution program, MDNS can resume immediate video data service by changing only IP address according to the domain name of media server. We can see that

As described above, according to the present invention, when a service failure occurs in the media server, the administrator can provide a fast and stable data service by changing only the IP address according to the domain name information of the media server in the MDNS.

In addition, preferred embodiments of the present invention are presented for purposes of illustration, and those skilled in the art will be able to make various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the scope of the claims You will have to look.
