DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0012]
FIG. 1 is a diagram showing a schematic configuration of a virtual domain system according to the present embodiment.
[0013]
As shown in FIG. 1, the virtual domain system according to the present embodiment includes a virtual domain system (virtual DNS system) 10 connected to the Internet 100, an information provider side terminal A, and an information user side terminal D. The virtual domain system 10 includes a virtual domain registration server B and a virtual domain server C.
[0014]
The virtual domain registration server B registers and manages virtual domain names (hereinafter referred to as virtual domain names). The virtual domain server C is a DNS (Domain Name System) server that links a virtual domain name and an original domain name (real domain name) registered in advance so that it can be used on the Internet 100.
[0015]
The information provider (acquirer of the virtual domain name) accesses the virtual domain system 10 via the information provider side terminal A and performs registration work for the virtual domain name that is virtually set. The virtual domain system 10 performs registration of a virtual domain name only in a virtual domain name database (not shown; hereinafter referred to as a virtual domain name DB) managed by the virtual domain system 10.
[0016]
An information user who accesses the information source of the corresponding virtual domain name operates the information provider side terminal A, and transmits a virtual address including the virtual domain name (hereinafter referred to as a virtual address) via the Internet 100. When accessed, the virtual domain system 10 is connected.
[0017]
A request with a virtual address (requested with (1) a virtual address name in FIG. 1) is obtained in a regular manner contained in the virtual domain name because there is no corresponding virtual address in a general DNS server on the Internet 100. An inquiry is made to the virtual domain server C that manages the domain name (official domain name) having TopLevelDomain (hereinafter referred to as TLD).
[0018]
In the virtual domain system 10, the virtual address is converted into an original address registered in advance so that it can be used on the Internet 100 (hereinafter referred to as a real address), and the IP address corresponding to the real address is converted to the information user terminal. Return to D (returns IP address (2) in FIG. 1).
[0019]
The information user terminal D can obtain information by accessing the target information storage destination (information storage destination server) E using the returned IP address ((3) IP address in FIG. 3). access). That is, the information user can call the target information by simply specifying the virtual address including the virtual domain name without specifying the regular IP address by operating the terminal D on the information user side.
[0020]
FIG. 2 is a diagram showing the virtual domain system 10 as viewed from the information provider side terminal A of FIG.
[0021]
The virtual domain server C manages a server C-a server C-b server C-c server C-d server C-e. The servers C-a to C-e are servers in which the provider (operator) of the virtual domain system 10 independently acquires domain names with different types (classifications) of TopLevelDomains (hereinafter referred to as TLDs). .
[0022]
In FIG. 2, as an example, the domain name of the server C-a is “aa.com”, the server C-b is “bb.net”, the server C-c is “cc.org”, and the server C-d is “dd”. .Biz ”and the server C-e are set to“ ee.arts ”, and the Generic TLD is set.
[0023]
The virtual domain name virtually set by accessing the virtual domain system 10 from the information provider side terminal A is registered ((1) in FIG. 2).
[0024]
The virtual domain registration server B passes the virtual domain name and the corresponding real domain name to the virtual domain server C ((2) in FIG. 2).
[0025]
The virtual domain server C writes the virtual domain name and the corresponding real domain name together, and after the writing is completed normally, returns a write completion notification to the virtual domain registration server B ((3) in the figure). In accordance with the TLD included in the virtual domain name, the information about the virtual domain name to which the servers C-a to C-e are linked and the corresponding real domain name is registered.
[0026]
FIG. 3 is a diagram showing the virtual domain system 10 as viewed from the information user terminal D of FIG.
[0027]
The virtual domain server C includes a first DNS unit (virtual DNS function) C-1 and a second DNS unit (DNS function) C-2.
[0028]
The first DNS unit C-1 has a function as a virtual DNS server. The function of the virtual DNS server is a function of converting a virtual address into a real address including a real domain name, instead of converting an address including a domain name into an IP address as in a normal DNS. The second DNS unit C-2 has a function of converting a real address including a real domain name converted by the first DNS unit C-1 into an IP address, like an ordinary DNS server.
[0029]
Next, an operation flow using the virtual domain system will be described.
[0030]
FIG. 4 is a diagram showing an operation flow between the information provider terminal (information provider side terminal) A and the virtual domain system 10 of FIG.
[0031]
The information provider accesses the virtual domain registration server B from the information provider terminal A via the Internet 100 in order to use the domain name used on the Internet 100 with the desired virtual domain name (step A1). Here, the information provider terminal A and the virtual domain registration server B may be connected using not only the Internet 100 but also a private network.
[0032]
Next, the virtual domain registration server B transmits virtual domain registration screen data to the information provider terminal A (step A2).
[0033]
On the virtual domain registration screen, the information provider selects the domain name of the information storage destination E that can be provided to the information user and the TLD to be used, so that the virtual domain name is input and transmitted to the virtual domain registration server B (Step A3). Here, biz is selected as the TLD name, and X is input as the domain name included in the virtual domain name.
[0034]
biz in the virtual domain system 10 dd. If the virtual domain registration server B receives the virtual domain name “X.dd.biz” as “X.dd.biz” in this case, whether the received virtual domain name is duplicated in the virtual domain system 10 Is compared with the virtual domain name DB in the virtual domain registration server B (step A4).
[0035]
If they overlap (in the figure, there is data), a message indicating that registration is impossible is returned to the information provider terminal A (step A5).
[0036]
When the information provider terminal A receives a message indicating that registration is not possible, a message indicating that registration is not possible is displayed (step A9), and the process returns to step A3 for re-inputting the virtual domain name.
[0037]
If there is no overlap in step A4 (there is no data in the figure), virtual domain registration server B passes the following expression to virtual domain server C (step A6).
[0038]
“× .dd.biz = corresponding real domain name” (b)
The virtual domain server C writes the expression (A) in the virtual domain name DB so as to link the virtual domain name and the real domain name, and returns the write completion notification to the virtual domain registration server B after the writing is normally completed ( Step A7).
[0039]
The virtual domain registration server B returns a message indicating that it has been successfully registered in response to the write completion notification to the information provider terminal A (step A8).
[0040]
The information provider terminal A displays a registration completion message and ends (step A10).
[0041]
FIG. 5 is a diagram showing a flow of operations between the information user terminal (information user side terminal) D and the virtual domain system 10 of FIG.
[0042]
The information user requests information from the information user terminal D over the network at the virtual address including the virtual domain name (step B1).
[0043]
When a request is made with a virtual address, a virtual address corresponding to the DNS server on the Internet 100 does not exist, so an inquiry is made to the virtual domain server C managing the domain name “dd.biz”. The virtual domain server C first collates the virtual domain name with the virtual domain name DB in the first DNS unit C-1 (step B2).
[0044]
If there is no virtual domain name data in the virtual domain name DB (no data in the figure), an error message is transmitted to the information user terminal D (step B3).
[0045]
The information user terminal D displays an error message and ends (step B4).
[0046]
When there is data of the virtual domain name in the virtual domain name DB (there is data in the figure), the first DNS unit C-1 converts the virtual address into a real address including the corresponding real domain name (step B5). ).
[0047]
Thereafter, the second DNS unit C-2 is used to convert the real address into an IP address (step B6), and the IP address is transmitted to the information user terminal D (step B7).
[0048]
The information user terminal D uses the received IP address to access the information storage destination E (step B8), acquires information, and ends (step B9).
[0049]
As described above, information providers can flexibly set domain names that are difficult to obtain as virtual domain names, while users can change addresses that tend to be complex and long to simple ones. Site operation using easily understandable address names becomes possible. That is, the virtual domain system 10 itself officially acquires its own TLD (for example, “virtual.com” is acquired, and the virtual address is set as “XX.virtual.com” .XX For the access to the corresponding virtual address, other normal DNS servers do not have an address corresponding to the corresponding virtual address. An inquiry is made to the virtual DNS server. Since this naming rule is not recognized by NIC which is a domain name management mechanism on the Internet, there is no name created on the Internet by this naming rule, and the corresponding virtual address on the Internet is unique.
[0050]
Further, data collection of a traffic system using an IPv6 system is planned, but data collection can be easily performed by using this embodiment. For example, register a predetermined number of virtual domain names, assign each virtual domain name to a device that can collect data from GPS, speedometers, wipers, etc. of vehicles used in taxi companies and transportation companies, and from all devices By collecting the information in real time, it is possible to analyze traffic information and weather information in detail.
[0051]
In the present embodiment, the present invention is not limited to this, and can be applied to a technique related to a virtual domain system suitable for applying the present invention.
[0052]
In addition, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to a number, position, shape, and the like that are suitable for implementing the present invention.
[0053]
In each figure, the same numerals are given to the same component.
[0054]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the effect hung up below.
[0055]
Users will be able to operate the site with shorter and easier-to-remember addresses. The information provider side can easily acquire a domain name that is strict and difficult to acquire, and can easily acquire a unique domain name. Furthermore, even if the information storage location is changed due to the change of the rental server, the change of the provider, etc., the trouble of changing the domain name is eliminated.
[0056]
In addition, since a new virtual domain name can be linked to a legitimate domain name registered in advance, a new virtual domain name is assigned to a computer or device that can be connected to the Internet, and information can be obtained from each computer or device in real time. It is effective for the use of systems that collect data.
