The present invention relates to an integrated address management apparatus capable of integrated management of Internet protocols such as IPv4 and IPv6, and more specifically, to integrated functions such as DHCPv4, DHCPv6, automatic address setting, and address setting using a user terminal name. It relates to an integrated address management device to provide.

Addresses that can be used in an Internet Protocol (IP) network can be set in two ways. The first method is to use the DHCP-generated address using DHCP (Dynamic Host Configuration Protocol), and the second method is to manually set the available addresses.

First, the DHCP protocol uses a DHCPv4 protocol in an IPv4 network and a DHCPv6 protocol in an IPv6 network. Each DHCP server maintains a pool of available addresses on the network and assigns a managed address to the terminal that made the address assignment request. Therefore, a network requires a module that provides a server function for DHCP and a client function for a user terminal. Therefore, in a network supporting both IPv4 and IPv6, a DHCPv4 server and a DHCPv6 server should be established, and the user terminal should be provided with DHCPv4 client and DHCPv6 client functions.

On the other hand, in the method of directly setting the usable address, the usable address is predetermined, and the user manually sets the available address. The other method of managing the address is the same in terms of the network.

Such a conventional address management system requires a separate management entity such as a DHCPv4 server or a DHCPv6 server for address management in a network when a network to which IPv6 is applied is newly established or an existing IPv4 network is supported to IPv6. However, there is a problem that inefficiency increases in terms of operation and management.

In addition, when the address is automatically set by the user terminal, since address management is not performed in the network, there is a problem in that it is difficult to introduce an authentication and charging policy for a user using the address.

In particular, since IPv6 address policy provides the function to automatically set the address by the user terminal, if the IPv6 address policy is introduced in the future, address management is not possible in the network. There is a problem that becomes difficult.

An object of the present invention for solving the above problems is to provide an integrated address management apparatus capable of integrated management of all the address resources in a network environment that supports IPv4 and IPv6.

A feature of the present invention for achieving the above-described technical problem relates to an integrated address management device capable of integrated management of IPv4, IPv6 address and autoconfiguration address resources,

A DHCPv4 server for processing an address assignment request using DHCPv4 from a user terminal;

A DHCPv6 server for processing an address assignment request using DHCPv6 from a user terminal;

Automatically set address management unit for receiving and processing the address information generated through the automatic address setting from the user terminal, and

And a connection manager for checking a port through which a packet is transmitted and received, checking a corresponding server to transmit the packet using the checked port information, and transmitting the packet to the identified server.

Here, the integrated address management device further comprises a user matching unit, the user matching unit

A server data management unit for managing address assignment and user registration status;

A log data processing unit that manages the transmission and reception of messages;

A user GUI processor configured to display information managed by the server data manager and the log data processor on a screen;

It is desirable to manage the address assignment status, user registration status and message transmission / reception records.

In addition, the connection management unit of the integrated address management device,

Port inspection unit for inspecting the port through which packets are sent and received,

It is preferable to include a packet forwarding unit for transmitting the received packet to the server using the port information checked by the port checker.

The integrated address management apparatus may further include a user terminal information management unit that stores and manages name and address information of the user terminal and performs a function of mapping name and address information of the user terminal.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the integrated address management apparatus according to a preferred embodiment of the present invention.

1 is a block diagram schematically illustrating a configuration of an integrated address management apparatus according to a preferred embodiment of the present invention. The integrated address management device performs a function as an integrated address management server. Referring to FIG. 1, the integrated address management apparatus includes a DHCPv4 server 100, an external DHCPv4 server interface unit 110, a DHCPv6 server 120, an external DHCPv6 server interface unit 130, an automatic configuration address management unit 140, The user terminal information manager 150, an external DNS server interface unit 160, a user matching unit 170, and a connection manager 180 are provided.

When the DHCPv4 server 100 receives an address assignment request using the DHCPv4 from the user terminal, the DHCPv4 server 100 performs processing thereof.

When the DHCPv4 server interface 110 requests an address assignment request using DHCPv4 from a user terminal and another server or node connected to the network performs a DHCPv4 server function, the external DHCPv4 server interface 110 connects to the corresponding external server and interworks with the address to the user terminal. Allow the assignment to be performed.

When the DHCPv6 server 120 receives an address assignment request using DHCPv6 from the user terminal, the DHCPv6 server 120 performs a process for this.

When the DHCPv6 server interface unit 130 receives an address assignment request using DHCPv6 from the user terminal and another server or node connected to the network performs a DHCPv6 server function, the external DHCPv6 server interface unit 130 connects to the corresponding external server and interworks with the address to the user terminal. Allow the assignment to be performed.

When the automatic address setting unit 140 receives an address generated through automatic address setting from the user terminal, the automatic address management unit 140 performs a function of managing address information received from the user terminal. In an IPv6 network, an address automatic configuration function is provided so that a terminal can generate and use an address based on address information available in a network. This function receives a message sent periodically from the network and generates an address that can be used based on the information of this message. That is, the router or a specific server of the network periodically transmits the prefix information that can be routed in the current network, and the terminal receives this message and combines the prefix information with its interface address information or an arbitrary value and generates the prefix information. Thus, the generated IPv6 address is in the form of "network prefix information + interface information" or "network prefix information + any value". In general, network prefix information has a 64-bit size, and since interface information or any value has a 64-bit size, an address having a total length of 128 bits is generated.

The user terminal information manager 150 performs a function of mapping the terminal name and the address information when the user terminal name is used instead of the address to transmit and receive data between the user or the server. Although this function is similar to the function of the existing Domain Name System (DNS), the existing DNS performs a function of mapping the address and the name of the server, but the user terminal information management module according to the present invention is the address of the user terminal. The difference is that it provides the ability to map names with. Accordingly, the user terminal information management module according to the present invention enables communication using names of user terminals as well as addresses in an IPv4 or IPv6 using environment. In other words, when communicating from a user terminal to a specific terminal or a specific server by using a name, it provides mapping information between the requested name and the address managed by the integrated address management server so that the address information for the name can be used. do.

The external DNS server interface unit 160 provides an interface function with an external DNS server so that address and name information managed by an existing DNS server can be used.

As shown in FIG. 2, the connection manager 180 includes a packet forwarder 200 and a port checker 210, and uses a port used in each protocol for transmitting and receiving DHCPv4, DHCPv6, and DNS messages. It checks and transmits the packet transmitted / received to each port to the corresponding processing module. The port inspecting unit 210 of the connection manager 180 performs a function of checking a port used in a corresponding server or a protocol for packets transmitted and received, and the packet forwarding unit 200 performs each port by the port inspecting unit. Performs a function to deliver packets delimited by the server to the server. For example, in the DHCPv4 protocol, the DHCPv4 server communicates using UDP Port 67, and the DHCPv4 client communicates using UDP Port 68. Accordingly, for packets transmitted and received on UDP port 67 or 68, the port checker checks the corresponding port, and the packet forwarder forwards the packet to a DHCPv4 server so that a necessary procedure can be processed. In addition, the port used in the DHCPv6 protocol, the DHCPv6 server uses UDP Port 546, the DHCPv6 client communicates using UDP Port 547, DNS communicates using TCP / UDP Port 53. In addition, ports for external DHCPv4 and DHCP46 server interfaces and ports for autoconfiguration address management may be arbitrarily designated.

As shown in FIG. 3, the user matching unit 170 includes a user graphical user interface (GUI) processing unit 300, a server data management unit 310, and a log data processing unit 320, and includes an integrated address management server. This function informs the administrator of the record, address assignment status, user management status, etc. of the message communication.

The server data management unit 310 of the user matching unit 170 manages an address allocation state and a user registration state, and the log data processing unit 320 manages a function state of a server, a message transmission / reception record, and the like. The GUI processing unit 300 performs a function of converting the information managed by the server data management unit and the log data processing unit into a form that can be viewed by an administrator to display on a screen or output to a printer. The items managed by the user matching unit having such a configuration are start and end times of the integrated address management server, message communication records and times transmitted and received by each server, data managed by each server, and the like. The data is periodically stored in a file format by the data management unit or the log data processing unit or displayed on the screen in the form of a picture or a table by the user GUI processing unit.

4 is a block diagram illustrating a client module that may be connected to an integrated address management server that is an integrated address management device. Referring to FIG. 4, the client module 450 includes a DHCPv4 client 400, a DHCPv6 client 410, an autoconfiguration address transfer unit 420, and a user terminal information transfer unit 430. The DHCPv4 client and the DHCPv6 client are functions that are basically provided in the case of a terminal using the Internet, and an address allocation scheme is also the same as that of the existing one. On the other hand, the auto-configuration address transfer unit 420, receives a message periodically transmitted from the network, extracts and stores the address information available in the network from the information of the received message, and manages the address information It can be used to create and use its own address.

The user terminal information transmitter 430 transmits terminal information used by the client module, that is, information such as an address and a name of the user terminal, to the integrated address management server.
