Description

IP address management method using user information

The present invention relates to an IP (Internet Protocol) address, and more particularly, to an IP address management method of matching an event occurrence associated with an IP address with a change point of user information of an Internet service provider (ISP). .

The IP address is a number for identifying each terminal in data communication. Each terminal must have a unique IP address.

Currently, IP addresses used in Korea are registered and managed in WHOIS DB managed by KRNIC (Korea Network Information Center), and each ISP can request additional IP assignment based on the WHOIS DB registration rate of IP address assigned to them. .

If a private individual, a company, an organization, or an organization (hereinafter referred to as a user) wants to access the Internet and use the Internet, when applying for Internet service to an ISP, the ISP allocates a part of the IP address assigned by KRNIC to the user. Is given.

Here, assignment means distributing an IP address to a user, and assignment means distributing an IP address from an ISP to a member ISP or from a KRNIC to an ISP for the purpose of assigning an IP address to a user.

Currently, KRNIC is entrusting ISPs to assign IP addresses less than a certain size (5 Class C). The ISP is responsible for registering the user information in the WHOIS DB for the assignment result, and the ISP is responsible for the registration.

This user information registration is done by providing KRNIC with the necessary information according to the form prescribed by KRNIC. ISPs register with WHOIS DB using IP Address Management System (IPMS).

This IP address management system is a system that automates the entire process of securing, allocating, managing, and retrieving IP address resources. Obtaining IP address, inquiring status of IP address assignment, managing IP address, preparing and sending IP address application and checking error, IP Performs functions such as address information search and IP address operation statistics.

However, it is essential to assign an IP address to a user to provide a service, but management of information related to IP address allocation is not essential. Therefore, IP address allocation information is not registered correctly because registration is not performed in a timely manner. have.

This registration problem can cause the IP address resources assigned to each ISP to remain unused and remain idle, or when an ISP cancels a service provided by an ISP, the ISP temporarily dedicates the IP address to another user. Was doing.

This problem occurs not only in the relationship between ISP and KRNIC, but also in the ISP (final node's ISP), which eventually assigns the IP address to the user even when a large ISP reassigns the IP address to another small ISP. IP addresses are not managed efficiently.

Accordingly, an object of the present invention for solving the above-described problems is to enable the user information of users who have been assigned an IP address to be registered without exception so that limited IP address resources can be efficiently used.

2 is a flowchart illustrating a method of managing an IP address resource using the IP address management method described above in a hierarchical model.

Figure 3 is a flow chart for explaining another embodiment of the present invention.

The IP address management method of the present invention for achieving the above object is characterized by using the service contract number of the user as a primary key (primary key) of the database for checking and changing the information related to the IP address.

In addition, the IP address management of the present invention consists of a parent node assigning an IP address and a hierarchy of child nodes assigned an IP address, and the child node registers information related to the IP address to the parent node using the IP address management system. The method includes a first step of confirming the service contract number of the user who applied for the Internet service, a second step of requesting an IP address assignment by transmitting the service contract number to the IP address management system, and a primary key of the service contract number. The third step of checking and changing the IP address resource for IP address assignment, and assigning the IP address to the corresponding user, and transmitting the user information related to the assigned IP address to the parent node to update the pre-registered related information. It includes four steps.

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

ISPs use a service contract number to indicate which user is receiving which Internet service, and the service contract number is first checked when a service request is received from a user.

User information about the corresponding IP address registered in the database for each event according to the service contract number because it is dependent on the service event using the new subscription / transition / addition / service contract number among the events related to the IP address assigned to the ISP. If you change it, user information about all IP addresses will be recorded.

In a relation database, where user information about an IP address is registered, a key field that uniquely identifies a particular tuple (column) within a relation (database table) is used to retrieve or record a specific record from a file. When sorting them, they use the primary key, which has the only value that is referenced first and which does not change.

Therefore, in the present invention, a service contract number generated when a service event occurs is used as a primary key of a database in which user information regarding an IP address is registered.

1 is a view illustrating an IP address management method for managing user information associated with an IP address using a service contract number according to the present invention.

If a user generates an Internet service event such as a new service request, a service change request, an IP address add request, or a service cancellation request to a ISP (①), the ISP searches for the service contract number of the user (②).

That is, the user applies for a desired service and provides his ISP with information about his network (such as the number of computers he currently has and the number of computers expected to grow in the future).

At this time, in the case of a new service application, a new service contract number is created and assigned to the corresponding user.

When the service contract number is found, the ISP requests the expected IP address to provide the service by attaching the service contract number found (or newly issued) to the IP address management system and the network information provided from the user (③).

That is, in the case of a new service application, the ISP provides the network information and the newly issued service contract number provided by the user to the IP address management system and requests an expected IP address requirement.

In the case of a service switch request, it requests the IP switch and the expected IP address requirement for the switch along with the service contract number found.

In the case of an IP address addition request, the user requests the expected IP address requirement according to the user's further request along with the user's network information (eg, the number of computers added) and the retrieved service contract number.

In the case of the service termination application, the service termination registration is also applied with the retrieved service contract number.

In response to such a service request, the IP address management system performs internal processing of the service (④).

That is, in case of a new application, the IP address management system calculates an appropriate IP address allocation size based on the user's network information and the currently available IP address resources provided by the ISP, and then selects an available IP among the IP addresses assigned from the upper ISP or KRNIC. Allocate an address as much as that amount.

In addition, in case of service switching, addition and termination, an appropriate size IP address is allocated based on the network information to be switched, or an appropriate size IP address is additionally allocated according to the network environment to be added, or a pre-assigned IP address is assigned. Delete information about it.

The IP address management system updates the previous user information on the IP address with the changed user information in the database related to the IP address information by using the service contract number as the primary key from the ISP when the IP address allocation is completed for the corresponding service.

When the internal processing is completed, the IP address management system transmits changed user information about the corresponding IP address to the ISP (or KRNIC) of the parent node so that the database information of the ISP (or KRNIC) of the parent node is updated with the changed user information ( ⑤).

The IP address management system then informs the ISP of the IP address allocation result for the user as a result of the processing (⑥).

As described above, by allowing the IP address management system to use the service contract number as the primary key of the database associated with the IP address, ISPs that want to process and receive service requests directly from the user are sent to the IP address management system whenever they want to provide the service. You must send the service contract number.

As the service contract number must be transmitted to the IP management system whenever the information on the IP address is changed, the IP address management system can recognize the change of all IP address resources and match the user information with the IP address information. By transmitting such information to the ISP or KRNIC of the upper node, it is possible to know the amount of resources allocated to each ISP and the amount of resources allocated to users.

As described above, in order for an IP address resource to be managed with a service event, a hierarchical model consisting of a node assigning an IP address (hereinafter referred to as a parent node) and a node assigned to it (hereinafter referred to as a child node) must be accommodated.

This hierarchical model can also be achieved between ISPs and between ISPs and KRNIC or between KRNIC and APNIC (Asia Pacific NIC).

2 is a flowchart illustrating a method of managing an IP address resource using the above-described IP address management method in a hierarchical model.

When a child event occurs, the child node first checks through the IP address management system how much available IP address resource among the IP addresses allocated from the parent node is available (step 201).

The child node checks the amount of available IP address resources and compares it with a reference value (step 202). If the available IP address resource is greater than or equal to the reference value, the child node allocates an appropriate amount of IP address based on the user's network information (step 202).

Of course, when the IP address is assigned, as described above, the user information related to the IP address is transmitted to the parent to update the database information of the parent node.

If the available IP address resource is less than the threshold, the parent node requests an additional allocation of the IP address resource (step 204).

When a parent node receives an additional allocation request for an IP address resource, the parent node searches an IP address management system of the corresponding child node or retrieves information registered in advance by the above-described IP address management method and the IP address resource assigned to the corresponding child node. The IP address resource assigned to the user is checked (step 205).

Based on the identified IP address resource allocations and quotas of the corresponding child nodes, it is checked whether the IP address resource addition allocation request conforms to the predefined IP address resource management rule "Provisions on Assignment and Assignment" (step 206). .

As a result, if the IP address addition allocation request is satisfied, the requested IP address resource is allocated to the child node (step 207).

The child node assigned the IP address resource returns to step 203 and allocates an appropriate amount of IP address to the user.

However, the request to add an IP address does not comply with the rule and rejects the assignment and notifies the child node of the reason (step 208).

If the child node has a lower node (grandchild node), the same method can be applied between the child node and the grandchild node.

3 is a flowchart illustrating another embodiment of the present invention.

In this embodiment, when the child node is the final node, the child node cannot be assigned an IP address directly to the user and can only apply for an IP address assignment to the parent node.

That is, when a child node receives a service from the user and an event occurs (step 301), the child node immediately requests an IP address assignment to the parent node together with the user's network information and the service contract number (step 302).

The parent node applied for IP address allocation calculates an appropriate allocation amount based on the network information of the user (step 303).

The IP address is assigned to the user through the steps 201 to 208 of FIG.

Of course, in the embodiment of Fig. 3, the order of steps 302 and 303 may be reversed. That is, after calculating the proper allocation amount to be assigned to the user in the child node, the parent node can apply for the allocation of the corresponding amount of IP address resources.

The embodiment of FIG. 3 is a case where the parent node in FIG. 3 becomes a child node in FIG. 2, that is, when the child node of FIG. 3 becomes a grandson node for the parent node in FIG. 2 and the grandson node becomes a final node. It is an embodiment that can be made.

As described above, by using the service contract number of the user as the primary key of the IP address management system, information related to the IP address assigned to the user by the ISP is registered at the time when the corresponding IP address is assigned to the user and thus the IP address resource. Can be efficiently managed, and furthermore, by matching the IP address with the user information, it can provide a basis for calculating various additional information using the IP information.
