Description

Device for automatically setting a LAPD protocal channel of the network system

The present invention relates to an automatic setting apparatus of a laby protocol channel of a network system, and in particular, by using a channel configuration database storing channel setting information of the LAPD protocol and information of the channel configuration database, the LAPD channel is automatically set during installation. The present invention relates to an automatic setting apparatus of a laby protocol channel of a network system.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In addition, in such a network, a multiplexing system is usually used to exchange information converted into an electric signal with a counterpart.

However, in the multiplexing systems as shown in FIG. 1, for example, in order to synchronize signals transmitted between respective nodes, for example, internal functional boards, for example, an OSI (open system interconnection environment) environment or TCP / IP. When using a protocol, a network that uses these standards uses a data communication channel (DCC) (70) and a link access procedure for the ISDN D channel (LAPD) protocol, which is usually the physical layer, for each node. And a layer 71, a network 72, a transport 73, an application layer 74, and the like. In this case, the network using the LAPD protocol should perform setup between nodes when porting and communicating.

At this time, the network using the conventional LAPD protocol as described above is configured to communicate with each other in a pair of network side and user side between each node.

Meanwhile, referring to FIG. 2, a method of setting up a network using the conventional LABD protocol as described above, when porting a LAPD protocol and transmitting a message or a file to a node, connection setup should be performed between nodes. A connection request is executed from node 75 configured as the user side to node 76 configured as the network side. Then, the network side 76 sets a fixed channel and transmits a response signal to the user side 75 to execute connection establishment. At this time, the connection setting must be a fixed setting so that the network side 76 and the user side 75 is a pair.

Therefore, when the call is connected and set as described above, when it is necessary to transmit data from the network side 76 to the user side 75, the other user side 75 receives data including destination and channel information in each hierarchical step. To perform normal network communications.

However, in the network using the conventional LAPD protocol as described above, the node and the channel are increased or decreased since the network setting for the network side and the user side must always be set in consideration of the network configuration to be connected to each node in advance. If the network configuration changes, the existing program must be modified every time the change is made, and accordingly, there is a problem that the LAPD channel setting task is very complicated.

Therefore, the present invention is designed to solve the above-mentioned problems, and it is possible to quickly adapt to the channel setting information of a plurality of equipment that is changed regardless of the increase and decrease of the number of nodes and channels, thereby maximizing the ease of use of the LAPD channel setting. It is an object of the present invention to provide an automatic setting apparatus for a laby protocol channel of a network system.

Another object of the present invention is to automatically set up the LAPD channel by changing only some setting function values without changing the whole program when installing the changed equipment. To provide a setting device.

The present invention for achieving the above object is a data link that determines the information of the network side and the corresponding user side as a reference and automatically set the channel information during the network installation using the LAPD protocol in the second layer therein A reference node device unit having a layer, a channel setting module configured to process channel setting information for a node of a network that is newly connected to the data link layer, and to set a channel to be paired with the linked node; The present invention provides an automatic setting apparatus of a laby protocol channel of a network system including a channel setting database providing channel state information of a corresponding link node stored in advance according to a search signal input from a module.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

In the device of the present invention, as shown in FIG. 3, information of a network side and a user side corresponding thereto are determined and a channel is installed when a network is installed using the LAPD protocol in a second layer therein. GNE (Gateway Network Element) having a data link layer (1) for automatically setting information, and channel setting information for a node of a network newly connected to the data link layer (1). And a channel setting module 3 for setting a channel to be paired with the linked node, and a channel for providing channel state information of the corresponding link node previously stored according to a search signal input from the channel setting module 3. It consists of a setting database (4).

Here, the channel setting database 4 calculates the number of cases in advance by virtually the case where the network configuration changes due to the increase and decrease of the node and the channel, and stores the calculated link setting information.

Next, the operation and effects of the present invention as described above will be described.

The apparatus of the present invention first connects and establishes a reference node device section 2 set as a channel of a network side as a reference, that is, a node 5 having a reference link set as a user side channel as a reference to a GNE.

Then, when the network data is transmitted and received by the reference channel as described above, when a new node 6 needs to be linked to the reference node 2, the nodes are physically connected to each other in the physical layer, and then the system is set up. .

At this time, the data link layer 1 of the reference node 2 transmits a channel setting request signal to the channel setting module 3 when a new node 6 is linked. Then, the channel setting module 3 searches the channel setting database 4 and searches channel setting data for which channel is allocated to the node 6 requesting the current link to form a pair and calculates the result. do. In addition, the channel setting module 3 allocates a channel to a pair of the reference node 2 and the newly linked node 6 based on the result data retrieved by the current channel setting database 4, for example, the reference node. (2) is the network side, and the newly linked node (6) assigns the channel to the user side and installs it automatically.

Then, the reference node 2 and the newly linked node 6 automatically transmit and receive a signal through a channel-allocated path, for example, a user request at the application layer 7B of the newly linked node 6. According to the present invention, necessary information packets are generated and loaded into the next data link layer 10B including error checking information and routing information in the header via the transport layer 8B and the network layer 9B. The data link layer 10B converts the information data loaded from the upper layer into the LAPD protocol and converts the information data loaded into the LAPD protocol through the DCC 11A of the reference node 2 currently linked to the pair via the DCC 11B. To 1).

Therefore, the data link layer 1 of the reference node 2 processes the information data transmitted from the newly linked node 6 by the LAPD protocol and loads it into the upper network layer 9A. At this time, the network layer 9A checks the routing area of the inputted information data, and if the current destination is correct, loads the received data into the upper layer, whereas if it is received incorrectly, it retransmits the data to the corresponding destination.

Meanwhile, the reference node 2 processes the received data and transmits the received data to the newly linked node 6 as opposed to the above process.

Therefore, according to the present invention, the channel setting module 3 connected to the reference node 2 is stored in the channel setting database 4 according to the number of relevant cases even if a plurality of nodes or channels are newly linked in addition to the previously linked nodes. Since the channel is automatically set by using the calculated channel setting information, the new node or link is increased or decreased as in the conventional apparatus, so that the new program is not newly modified.

As described in the above description, the present invention automatically sets the LAPD channel at the time of equipment installation by using the channel setting database storing the channel setting information of the LAPD protocol and the information of the channel setting database, thereby increasing or decreasing the number of nodes and channels. It can quickly adapt to the channel setting information of a large number of devices that are changed regardless, and thus has the advantage of maximizing the ease of use of the LAPD channel setting.

In addition, according to the present invention, since the LAPD channel is automatically set by changing only some setting function values without changing the entire program when installing the changed equipment, the stability of the LAPD channel setting is significantly improved accordingly.
