Description

Dynamic Naming Service Method and Technology Supporting Dynamic IP {Method & Technology of Dynamic Naming Service}

The present invention is a technique designed to solve the problem that a fixed IP address is necessary to access a specific site on the network in the current technology that implements network management or Internet service through a fixed IP address in the Internet technology field.

In order to use the Internet, the IP address method is used by using the TCP / IP protocol. Generally, services provided by an Internet service provider use a fixed IP method and a dynamic IP method. The fixed IP method is used for use as a server in which an address to be always connected in connection with a leased line is used. In contrast, the floating IP method is used for individual users who do not need to maintain a constant address only for the function of making the Internet available. Used by service providers to provide one-time IP addresses for services such as dial-up and cable modems. Current system for web service for user's homepage or file transfer service for file transfer has PC or server-class computer which is to be used as web server, fixed IP address and fixed line for connecting to internet. In order to be more convenient, a URL called a domain name should be provided. In addition to this method, a certain amount of hard disk space must be provided on the equipment of the web hosting company so that the web service can be provided through the web hosting company having the above-mentioned requirements. Dedicated methods are also used. When you receive a leased line service from a leased line service provider, you will be given a static IP address to use by default, and you will be able to connect to the URL via InterNIC or krNIC using this IP address unless you terminate the leased line service. Because it is an immutable address that never changes, the connection to the URL is also available as an initial one-time setup.

In many Internet service providers that provide Internet service through various access means including modem access, a floating IP address scheme is provided temporarily and randomly at the time of the user's connection in order to make a limited number of users use the IP address. I'm using. Therefore, every time a user executes a connection, a different IP address is assigned to the user, thus allowing the user to access the remote site only one way through the Internet, and other users cannot access their local site. The significance of the present invention has an important meaning because it has a fatal disadvantage of not being able to use a web service for a homepage service or a file transfer service for file transfer.

The present invention is designed to solve the problem of a system that does not use a fixed IP address as described above, and has a flexible IP address that is temporarily and randomly assigned by a company through an Internet service provider when connecting to the Internet. Its purpose is to enable web services and file transfer services.

In order to achieve the above object, as shown in FIG. 1, the client-side computer 101 receives data obtained through a process of authenticating the user's information and receiving a dynamic IP address and recognizing the data. 105, using the information transmitted from the server side computer 105 to generate a unique URL and to connect to the Internet user computer 104 to use the web service provided by the client side computer (101) Technical implementation of the configuration for the step of connecting so that the connection, and the step of establishing a web server and a file transfer server to perform a web service and a file transfer service in the client side computer 101 is a technical problem.

Other objects and advantages of the present invention in addition to the above objects will become apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, a detailed block diagram of the configuration example shown in FIG. 1 is shown. The client module 202 receives the user information and finds the floating IP address given by the ISP company 102, and the resulting user information data 201 and IP address data 203 are obtained through the Internet 204. The process of transmitting to the module 206 is performed. The transmitted data is used as data for performing a dynamic naming service in the server module 206. In addition, the server module 206 transmits an active status confirmation signal indicating whether the server is connected to the server module 206 at each time of the period 207 designated by the server module 206 to notify the server module that the server module 206 is connected to the network.

Meanwhile, the server module 206 designates a user's path using the transmitted user information 201 and the IP address 203. This is in the form of Http: // [server domain URL] / [client username] or Http: // [client username]. URL] /, where the server module stores the URL initially generated by the user information 205 so that it can be fixedly used later. The generated URL is connected to the IP address 203 sent with the user name in the client module 202, so that the server module 206 performs an operation that is later recognized by the internet user 209. By entering only the IP address 203 of the client module 202 can be found.

3 is a block diagram illustrating in more detail the client module 202 shown in FIG. In FIG. 3, the client module 202 may include a data input unit 301 that receives user information 201, an IP address 203, an active state checking period 310, and the like, and user information 201 and an IP address 203. Communication with the server via the Internet and the Internet server module 312 to provide a web service and a file transfer service to the data transmission unit 302 and the Internet user 209, which transmits an activity check signal to the server module 206. Socket 308.

The data input unit 301 serves to supply the received data to the data transmission unit 302. To this end, a user information input unit 303 for receiving a user ID and password from a client side user and an IP address 203 detected from an ISP company 102 are detected and supplied to the data transmission unit 302. An active state checking period receiving unit which receives the period 310 of the active state checking signal from the unit 306 and the server module 206 is provided. The user information input unit receives an ID and password from the user, and the IP address collection unit 306 obtains an IP address from the socket 308 connected to the ISP company 102. The two data are sent to the server module 206. It is supplied to the user information transmitter 302 side for transmission. In order to inform the server module 206 that the client module 202 is up, an active state confirmation signal should be transmitted at a predetermined period, and the period 310 designated by the server module 206 is activated to determine the transmission period at this time. It is input through the status check period receiving unit 309.

The data transmitter 302 includes a user information transmitter 304 for transmitting the supplied user information and an IP address to the server module 206 and an active state confirmation signal output unit 311 for outputting a signal indicating an active state. The user information transmitter 304 transmits the supplied user data 305 to the server module 206 through the socket and performs the active state confirmation signal at every output period 310 of the active state confirmation signal input from the server module 206. The output unit 311 outputs an active state confirmation signal. In this case, the socket 308 is applied to the client module 202 to the server module 206 or vice versa as a means related to data transmission and reception, and serves to access the ISP company 102 and obtain an IP address.

Finally, the Internet server module 312 is responsible for processing when an Internet user attempts to connect to the client module 202.

4 is a block diagram illustrating in more detail the server module 206 shown in FIG. In FIG. 4, the server module 206 is a data transceiver 402 which is responsible for transmitting and receiving data and a data processor 403 which processes the received data and generates data to be transmitted to the client module 202. It consists of.

The data transceiver 402 includes a data transmitter 408 and a data receiver 404 for receiving and transmitting data through the socket 401. The data receiver 404 receives a user ID, an IP address, and an activity check signal, which are user data transmitted from the client module 202, through the socket. Also, the data receiver 404 receives a cycle 409 of the active check signal and the received user. The data transmitter 408 is used to transmit the authentication result data 413 by the data to the client module 202.

The data processing unit 403 may include a user authentication unit 406 for authenticating the user data 405, an active state confirmation signal authentication unit 407 for checking an active state confirmation signal, and an active state confirmation signal in the client module 202. An active state check signal cycle generation unit 410 for generating a cycle to designate a cycle for transmitting the network, and an Internet user socket 412 for specifying an address where an Internet user accesses the Internet server of the client module 202. Equipped.

The user ID received by the data receiving unit 404 is compared with the information constructed in the user database and authenticated to verify that the user authentication unit 406 performs this operation and the active state confirmation signal authentication unit In operation 407, the client module 202 checks the activation status confirmation signal transmitted to inform whether the client module 202 is activated, and supplies the result value 413 to the data transmitter 408. In addition, the active state check signal period generator 410 receives a period value from the server module 206 manager and supplies the value to the data transmitter 408.

The Internet user socket 412 plays a large role. First of all, URL generation for access to the client module 202 by an Internet user is the first role, and the method of generating the URL can be understood as the following example.

Example> If the server module URL is http://xyz.co.kr and the user ID is abc

① Client Module URL = http: // [Server Module URL] / [~ Client User ID]

= http://xyz.co.kr/~abc

② Client Module URL = http: // [Client User ID]. [Server Module URL] /

= http://abc.xyz.co.kr/

The generated URL is connected to the dynamic IP address of the client module 202 so that the Internet user can forward to the URL of the actual client module 202 using the URL. In this way, the Internet user can use the Internet service provided by the actual client module 202.

5 is a flowchart illustrating a processing method of a client module 202 in a dynamic naming service method according to an exemplary embodiment of the present invention. The flowchart of FIG. 6 relates to the operation principle of the client module 202 and will be described in detail as follows.

First, the client module 202 needs to collect data to be transmitted to the server module 206. The client module 202 receives a user ID and password from the user (step 501) and communicates with the server via the Internet for communication with the server module 206. (Step 502) When the connection with the server module 206 is completed, the server recognizes and obtains the IP address assigned in the connection process with the ISP 102 (step 503).

After completing the process of collecting the user ID and password, and the IP address information received from the ISP company 102, the collected data is transmitted to the server module 206 (step 504) and the server module using the transmitted data. If the authentication result is not correctly authenticated in step 505, the connection is terminated immediately (step 508). In step 506, the active state check period data is received from the module 206.

The received activity check cycle data is a cycle of transmitting the activity check signal of the client module 202, which tells the server module once every how many hours it will inform that the server is still active. At step 507, the connection to the server is terminated (step 508). At this time, the connection with the server is reconnected the next time the activity is transmitted, and after the transmission is completed, the connection is terminated. Will exit again.

When the Internet user attempts to access the IP address of the client module 202 through the server module 206 (step 509), the client module 202 provides the Internet service to the Internet user (step 510). If there is no access, it will be idle.

6 is a flowchart illustrating a processing method of the server module 206 in the dynamic naming service method according to an embodiment of the present invention. 6 is a flowchart illustrating an operation principle of the server module 206, which will be described in detail as follows.

The client module 202 needs to connect to the server module 206 and transmit user data. For this purpose, the server module 206 is in a state of always waiting for the client module 202 to connect through the Internet (step 601). Next, the user information data 201 transmitted from the client side is received through the socket connecting the Internet (step 602).

The user ID is extracted from the transmitted user information data, and at this time, the user authentication is performed to check whether or not a matching user ID exists in the user information database constructed at the server module 206 by using the extracted user ID. If the user ID of the client module 202 exists in the database in the user authentication step, the server module 206 receives the IP address of the partition system that will receive the activation status confirmation signal. In step 604, the client module 202 stores the current IP address value of the client module 202 in the database by connecting it to the user ID. In step 605, the client module 202 connects. End (step 606).

If the information corresponding to the user ID of the client module 202 does not exist in the user information database in step 603, the connection of the client module 202 is immediately terminated (step 606).

Thereafter, the server is in a waiting state for checking whether there is a process of accessing the client module 202 by the Internet user (step 607). If an access by the Internet user is attempted, the user ID for which the access request is attempted is made to the database. In operation 608, the client checks whether the client module 202 is activated by checking an active state confirmation signal of the client module 202. In operation 605, if the client module 202 is activated, the database is checked. By connecting the IP address stored in the Internet with the URL requested by the Internet user to proceed to receive the Internet service provided by the client module 202 (step 610), if the client module 202 is not activated, the client module End without allowing access to the 202.

In step 607, if there is no request for access to the client module 202 of the Internet user, the user waits for the user request.

As described above, a dynamic naming service method and technology for supporting a dynamic IP address according to the present invention does not provide a fixedly available IP address such as a leased line, but a connection to the Internet is provided to receive a service provided by the Internet. This can have the same effect as a service that provides only IP addresses randomly and flexibly given by an Internet service provider, or a fixed IP for users who use the service.

This effect can reduce the burden on users receiving Internet services, paying expensive Internet leased line and fixed IP address fees. Therefore, it is possible to provide Internet content services such as web server and file transfer server in not only server-class system connected to the Internet through leased line but also PC-class system connected via dial-up. You can avoid the use of high-quality services with the same amount of storage space available on your system.

Second, it can be suggested as a solution to the IP address shortage caused by the occupation of fixed IP addresses. The current IP address system, which is represented by periods separated by periods every 8 bits in a 32-bit bit string, becomes severely lacking. In 1994, Internet Protocol next generation (IPng), a next-generation protocol with 128-bit address space, was standardized. The shortcomings can be eliminated by solving the fixed IP address occupancy problem by the present invention, improving the efficiency of IP address sharing, and furthermore, changing to the URL-based address method according to the present invention rather than the IP-based Internet address method. You can also expect.

As described above, the present invention has been described with reference to the exemplary embodiments illustrated in FIGS. 1 to 6, but those skilled in the art can make various modifications and changes to the present invention without departing from the spirit of the present invention. It will be appreciated that this is possible. For example, the server module can be configured and operated by multiple systems divided into naming server, database server, web server, etc. instead of one system. Furthermore, it can be configured as distributed processing system using distributed network. It can also be configured to use an external server without having an Internet server directly.

Therefore, the technical scope of the present invention is not limited to the contents described in the detailed description of the specification, but should be defined by the following claims.
