BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic address registration method in an Asynchronous Transfer Mode (ATM) local area network (LAN) system, and more particularly to a method of registering addresses of users in a local area network To a method whereby users' devices simultaneously and automatically register their respective addresses in a local area network (LAN).

In the conventional LAN, communication is performed using the TCP / IP protocol, and the physical transmission layer used at this time is mainly Ethernet.

In this case, the address used is an Ethernet address and an IP (Internet Protocol) address. The Ethernet address is not specified by the network administrator or the operator, and the method specified by the manufacturer of the Ethernet product is used.

In addition, the IP address uses a method of manually registering each user by a network administrator who manages an IP address designated in a network information center (NIC = Network Information Center).

However, local area networks using ATM technology do not use Ethernet addresses and IP addresses.

Also, ATM LAN requires a real-time address registration method with each user. Therefore, it is impossible to use a method of manually registering an address manually by a network administrator or an operator.

Of course, a network manager or an operator can manually register an address using a conventional method in a place where address registration is not required in real time, but there is a problem that an unnecessary manpower is required due to cumbersome operation.

Accordingly, an object of the present invention is to reduce manpower by manual operation by registering addresses of all users in an ALAN-ES (ATM-LAND Edge System) used in ATM LAN in an automatic and real-time manner .

In order to achieve the above object, there are three methods of automatically registering each user as follows.

A method of automatically registering an existing address in a company that manufactures user devices in such a manner that a unique address is previously allocated to each device and the registered address is automatically registered in a local area network.

Second, since the devices used in the local area network are not manufactured by the same company, it is a way to solve the problem that occurs because all the user devices can not have unique addresses like the conventional Ethernet.

That is, when the address is registered in the first method, when the corresponding address is already registered in the network side of the local area network, automatic address registration can be performed by using the following two methods.

One is that each user device has one or more different addresses.

In this case, if you try to register as the first address, then you have to register with the next address.

Another method is to create a new scam that is not used in a network side network system (in the case of the present invention, ALAN-ES system) and provide it to each user.

This second method is called automatic re-address registration of existing addresses.

Finally, the third is that when the system of the user who wants to connect to the local area network does not provide the automatic address registration method, the user registers the new address manually.

By performing such a method, the present invention is not to manually register each user in the ATM local area network, but allows each user to be automatically registered simultaneously with connection to the LAN .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention operates in the System Control Processing Block (SCPB) 10 of FIG. 1 and is executed in an Address Registeration Function Block (ARFB) 15 of FIG.

FIG. 1 is an ATM-LAN ES structure diagram.

In FIG. 1, the user data is input through an ATM user interface module (AUIM) (30, 40, 50, 60) and connected to an ATM cell switch module (ACSM) , 70).

At this time, data is transmitted to the backbone through the ATM backbone interface module (ABIM) 80, which is the data pointing to the backbone system.

However, data destined for another ATM user interface module (AUIM) in the same system switches to the corresponding AUIM in the ATM cell switching module (ACSM, 70).

Conversely, the user data coming from the backbone side is input via the ATM backbone interface module (ABIM 80) and is transmitted by the ACSIM 70 through the corresponding AUIM (30, 40, 50, 60).

In order to transmit data to these users, a Layer Control Processing Block (ACPB) 20 directly controls the hardware of the AUIMs 30, 40, 50 and 60, the ACSM 70 and the ABIM 80, And OAM (Operation And Maintnance) functions.

In the system control processing block (SCPB) 10, a function for executing communication with an operator who operates the ALAN-ES system, a signal, a routing function, an address registration function, and the like are collectively executed. As shown in FIG.

Referring to FIG. 2, a Man Machine Interface Block (MMIB) 14 performs a communication function with an operator who operates the ALAN-ES system through a console terminal. To the system management function unit (SMFB: Signaling Block 13) and the address registration function units (ARFB) 15, analyzes the data transmitted from the respective blocks, and reports the data to the operator .

The system management function unit (SMFB) 12 interprets the data sent from the MMIB 14 according to an instruction of the operator and executes the indicated command, and the hardware related information is transmitted to the ATM layer And transmitted to the control processing unit (ACPB 20).

In addition, the system allocates resources of the system while exchanging messages with the signal processing unit (SIGB) 13 and the address registration function unit (ARFB) 15, and performs functions such as isolating a failed area or releasing the failed area.

The SIGM 13 interprets the signal related data displayed through the IPCB 11 and executes it. The SIGM 13 performs functions for routing and transmits information related thereto to the SMFB 12, the MMIB 14, the ARFB 15 ).

The address registration function unit (ARFB) 15 registers the address of the corresponding device when the new subscriber unit (or user equipment) wants to access the local area network, and also registers the registered address It checks periodically and is responsible for organizing these addresses if there is no device at that address or if a failure occurs.

The MMIB 14 exchanges related information through the SMFB 12 and the SIGB 13, and interprets and organizes the information displayed through the IPCB 11.

3 is an address registration flow according to the present invention.

First, when a program is executed, a local area network connection request is received through the IPCB 11 (S1).

(S2) whether the device to be connected to the local area network supports the automatic address registration function.

If the function is supported by this determination, the address already existing in the corresponding access device is registered (S3)

It is confirmed that the registered address is normally registered (S4). In the normal case, the address of the system is updated to the address (S7), the report is made to the operator (S8), and the process is terminated.

When the registered address is in an abnormal state, that is, when it is desired to register an address using an existing address, another address already existing in the connected device of the user is automatically re-registered and a new address is registered in the local communication network side Receive.

However, it is confirmed again whether the newly registered address is a normal registration (S6), and if it is normal, the address of the system is updated (S7), reported to the operator (S8), and the process is terminated.

However, if it is abnormal even by this confirmation (S6), it is reported to the operator (S9), and the address of the device to which the report operator directly accesses is registered as a device which does not support automatic address registration (S10).

Thereafter, the address of the system is updated with the registered address (S7), reported to the operator (S8), and the process ends.

In the case of the access device of the user who does not support the automatic address registration, the device notifies the operator (S9). Since the device does not support the automatic address registration, .

Thereafter, the address of the system is updated with the newly registered address (S9), reported to the operator (S10), and the process is terminated.

In the present invention as described above, the address of each user device can not be automatically registered in the conventional LAN, and the network administrator or the operator must manually register the address of each user manually.

However, in the present invention, it is possible to perform address registration by using an automatic method of addressing all the users connected to the communication network in real time.

In this way, a network manager or an operator who manages a LAN is not required to register an address every time each user accesses the network, thereby enabling more efficient network management than the conventional method.

In the case of the present invention, the automatic address registration function is performed using the three modes, so that a device that does not implement the present invention can be easily connected to a local area network.
