Description

A MANAGEMENT GATEWAY SYSTEM FOR TRANSMITTING A MANAGEMENT MESSAGE FROM NETWORK MANAGEMENT TO CO-LAN AND THE METHOD}

The present invention relates to a method for managing a corporate public private network through an integrated network service management system, and more particularly, to efficiently manage a management message between an integrated network service management system and an exchange that constitutes an open structure corporate public data network (CO-LAN). The present invention relates to a management gateway system and a management command processing method for performing the operation and management of an exchange system openly.

In general, a data communication network is implemented with various communication devices for various models. Under these conditions, network operators require collective management of their networks, and demand for them is increasing. In addition, collective management of various communication devices is the basis for providing more improved quality services.

In the conventional exchange management method, a human-to-machine language between the exchange and the operator is provided so that the network operator can perform various tests, measurements, or content changes related to operation and maintenance of the exchange system through the input / output device. language) to operate and maintain the exchange.

However, this management method is dependent on the operator's experience and knowledge, which is absolutely influenced by the operator's command, and requires an operator with expertise in a specific model, making integrated resource management difficult. . The management problems of these systems are likely to significantly degrade the performance of the system.

Therefore, a consistent and systematic network management technology has been developed to maintain the consistency of services for various communication networks. If there is an integrated network service manager, the management command from the manager can be delivered to the exchange to enable the management of the exchange, and the management gateway system and the conversion process to accurately apply and reflect the command from the manager to the exchange need.

To this end, a management scheme for interoperability of arbitrary network elements is actively being developed through communication using a standard interface called CORBA between a service management system and a management gateway system. For the existing data network exchange that can interoperate with this management method, a management gateway system is placed between the integrated network service management system and the exchange to convert management commands from the management system into commands that can be executed in the exchange.

However, when interworking the corporate public private network (CO-LAN) with the integrated network service management system, there are many problems in passing the management command to the exchange.

1 is a structural diagram of a management gateway system 5 and an operating terminal system 11, 12 for a typical corporate public private network.

Referring to Fig. 1, the switch 21, 22, 23, 24 has a structure dedicated to the specific operating terminal system (11, 12). That is, the first operating terminal system 11 is in charge of the first exchanger 21 and the second exchanger 22, and the other second operating terminal system 12 is the third exchanger 23 and the fourth exchanger 24. Will be in charge of In this way, the corporate public private network has a structural feature that is responsible for partitioning the exchange by region or function according to the performance and role of the operating terminal system.

Therefore, in order to execute a management command transmitted from the integrated network service management system, it is necessary to first determine which operating terminal system a component for the management command belongs to. Currently, such a decision is processed by the operator's experience or manual operation through command execution, and thus there is a problem that the work efficiency is lowered.

Because of the characteristics of each exchange, it is possible only through the operating terminal system. Therefore, it is necessary to know the operating terminal system in advance, and if it is not known, it is necessary to perform the repetitive input operation to create, delete, change or search the components of the exchange. There is a problem to search the exchange.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problem, and its object is to receive a management command from an integrated network service management system in a corporate public private network (CO-LAN) and to select a suitable exchange to perform the management command. The method for the method is presented.

2 is a structural diagram of an integrated service management system and a management gateway system according to the present invention. As shown in FIG. 2, the integrated service management system 40 manages the enterprise public private network through the management gateway system 50. The management gateway system 50 is divided by function for the integrated network service management system 40 corresponding to the category of the managed service. In detail, the management gateway system 50 includes a configuration management gateway server 52 that is responsible for configuration management of components, a connection management gateway server 53 that is responsible for managing connection management, and a corresponding server. The application program interface converting unit 58 automatically converts the received management commands into the application program interface commands required by the exchange, and the application program interface that appropriately distributes the automatically converted commands to the exchange and receives and returns the results. It consists of 60. Then, a failure management gateway server 54 for processing and delivering failure information transmitted from the exchange, and a failure management gateway server for testing a corresponding component from a failure reception or occurrence of failure information from a user and handling the failure ( 55) and a data collection processor 59 that periodically collects performance information on the managed components. Changes to the configuration information, failure occurrence information, or performance related information are stored in the database 56 for each component or service to improve the persistence of the related information.

Management commands generated from the integrated network service management system 40 are received through a standard interface called CORBA, and are transmitted to the corresponding servers 52, 53, 54, and 55 through the Ethernet board of the management gateway system 50. Delivered. The server is defined by function, and after searching the relevant database 56 for a component to execute the corresponding administrative command, and if there is a component to perform the corresponding administrative command, the application program interface converting unit executes the corresponding administrative command. Is automatically changed to the application program interface command required at the exchange and forwarded to the exchange. At this time, the management command should determine which operating system is dedicated to the exchange (or node), board (PE) or port (Port) to carry out the management command.

The conversion procedure of the management command is dependent on the exchange constituting the network component, and in the present invention, the BNS-2000 exchange, DK-II, MPC, SAM exchange, etc., which occupy most of the enterprise public data network, can be targeted. have.

The procedure for determining an operating terminal system such as an exchange to perform a management command is performed by the application program interface conversion unit through which the service management command transmitted from the integrated network service management system passes through the servers 52, 53, 54, and 55 in the corresponding management gateway. After the conversion is completed successfully at 58, the process proceeds before the application program interface command converted by the management gateway server is called. Reference is made to the relevant location information table of the database unit 56 in order to confirm which operating terminal system the component is configured. The location information table of the database unit, which is one of the features of the present invention, will be described in more detail with reference to FIG. 3.

The application program interface command is transmitted to the command processing interface in the exchange through an operating terminal system (not shown). It is passed to the component to execute the management command and return the result of the command. If the result of the command is successful, the servers 52, 53, 54, and 55 in the management gateway add, delete, or change attribute values existing in the table for each component of the database unit 56. .

As such, the integrated network service management system 40 and the management gateway system 50 have a hierarchical structure. The integrated network service management system 40 generates a service management command to physically or logically divide the management gateway. It delivers to the system 50 a management command to the exchange.

The integrated network service management system 40 and the management gateway system 50 may be implemented as a database unit 56 for storing mutually open interfaces and component management data in a conventional workstation, and the management gateway system 50 ) Analyzes the service management command delivered to the mutually open interface and delivers it to the application program interface converting unit 58. The application program interface converting unit 58 converts the delivered message into an internal management command form for the corresponding exchange. Play a role. Such a command conversion algorithm is performed by the management gateway system 50, and when the command of the integrated network service management system 40 is received, it is easy to find an operation terminal system to perform the corresponding command and automatically perform the corresponding management command. Do it.

Hereinafter, the management components managed by the integrated network service management system 1 and the management gateway system 11 to which the present invention is applied will be described. In the currently used data network, various kinds of exchanges provide various kinds of services. In order to manage these various kinds of nodes collectively from a service perspective, an abstracted information model is required. As follows.

A node represents a node operating in a network. In the existing data network, there are a BNS-2000 and DK-II switching system for a backbone node and an MPC and SAM switching system for an access node. A link represents a node and a link connecting the nodes, and a board is used to provide a synchronous / asynchronous service on a board supporting specific services (Ty-12, TSM8, MSM, TSM, X.25). Represents a processing device on which software is executed. In addition, a port represents a physical interface through which data is actually transmitted and received, and in the case of MPC and SAM, the number of ports supported on one board and the transmission speed of the port are determined according to the type of service. Refers to the physical element being

The above has described the components that are managed as management components in the management system and management gateway system to which the present invention is applied, and the management commands for creation, deletion, change, and retrieval of the corresponding components from the integrated network service management system are managed gateway systems. Is processed from

Fig. 3A shows a node configuration information database table structure for storing management information on node components employed in the present invention. This table manages information and status values for the exchange (node) and is the main table to which the present invention is applied. The node configuration information database table has the following attribute values. Node ID 81 is a unique identifier representing the exchange, and node name 82 is a name representing the exchange, and has a unique string value in the enterprise public data network, and all management commands through the operating terminal system. Is passed as the node name. The nodeflag 83 also has an integer value as a field indicating which operating terminal system the exchange is located in. Initially set to a null value. The operation state (24) is a value representing the operation state of the exchange and indicates whether or not the current service is available.

3B illustrates a board configuration information database table structure for the management gateway to store management information about board components in the present invention. This table manages the information and status of the boards mounted on the exchange (node). It has the following attribute values. Board ID 86 is the only identifier that represents the board. The node name (87) is a name representing the exchange to which the board belongs, and has a unique string value in the corporate public data network. All management commands through the operating system are transferred to the node name. The operation state 88 is a value representing an operation state of the corresponding board and indicates whether or not the current service is available. The service type (29) is a value indicating the type of service supported by the board.

3C illustrates a port configuration information database table structure for the management gateway to store management information on port components in the present invention. This table manages the information and status of the ports that are serviced by the board, and has the following property values. The port ID 91 is the only identifier that represents the port. The board ID 92 is a name representing a board to which the corresponding port belongs, and has a unique string value in the enterprise public data network. The operation state 93 is a value representing an operation state of the corresponding board and indicates whether or not a service is currently available. The service type 94 is a value representing a service supported by the corresponding port.

4 is a flowchart showing a management command processing method according to the present invention.

When initially initialized, the configuration information table of the management gateway system is set to an initialization state (101). After the system has been successfully initialized, if any management command is sent from the service management system, the management gateway system determines which component the command is for. If it is a management command for the node (102), the node flag field of the node configuration information table managed by the management gateway system is searched. For example, if the field value is set to 1, it indicates that the operating terminal system 1 manages the node and requests connection to the operating terminal system. If the field value is set to 2, this means 2 Since the operating terminal system No. 2 manages the corresponding node, a structure requiring a connection to the operating terminal system No. 2 is achieved.

At this time, if it is set to NULL (104), in order to check which operating terminal system the node is connected to, it sequentially requests access to the operating terminal system (105), and the number of the successful operating terminal system is If present (107), it is reflected (108) in the node flag field of the node configuration information table managed by the management gateway system. When the next management command is requested for the node, the information of the operating terminal system reflected by the processing result of the first required management command is managed in the node configuration information table so that the configuration can be performed at once without access to the sequential operating terminal system. Accessible by element.

If it is a management command for a board (110), after obtaining node information to which the board belongs from the board configuration information table managed by the management gateway system, the node flag field of the node configuration information table is searched from the obtained node information (111). ). Similarly, if the corresponding field value is set to 1, it indicates that the operating terminal system 1 manages the node and requests connection to the operating terminal system. If the corresponding field value is set to 2, it operates twice. Since the terminal system manages the node, it has a structure that requires connection to the No. 2 terminal system. At this time, if it is not set to NULL, it requests a connection to the corresponding operating terminal system (114), and if it is NULL (112), sequentially checks which operating terminal system the node is connected to. The system requests access to the system (113), and if the connection is successful (115), the operating terminal system number is reflected in the node flag field of the node configuration information table managed by the management gateway system (116).

If it is a management command for a port (118), the board configuration information table is obtained again from the board information obtained from the port configuration information table managed by the management gateway system, and after obtaining the node information to which the board belongs from the board configuration information table, The node flag field of the node configuration information table is retrieved from the obtained node information (119). If not, the connection is requested to the operating terminal system according to the field value (122). If it is set to NULL, in order to check which operating terminal system the node is connected to, it sequentially requests access to the operating terminal system (121), and if successful (123), enters the number of the operating terminal system. It is reflected in the node flag field of the node configuration information table managed by the management gateway system (124).

As in this procedure, only when the node flag field value is set to NULL, the connection request is sequentially made to the operating terminal system. However, when the next management command for any component is required, the processing result of the first required management command is processed. By managing the information of the operating terminal system reflected by the node configuration information table, it is possible to access the corresponding components at once without access to the sequential operating terminal system.

The present invention described above is not limited by the above-described embodiment and the accompanying drawings, but by the appended claims. Therefore, it will be apparent to those skilled in the art that various forms of substitution, modification, and alteration are possible without departing from the technical spirit of the present invention described in the claims.

As described above, the method for processing management commands of the management gateway system and the integrated network management system for the corporate public private network according to the present invention, by collecting the information generated from each exchange to determine the status of each exchange to the entire network dimension and service Decisions at the dimension point of view enable the most appropriate action for the exchange system. In addition, the network management system to which the exchange belongs belongs to be managed in the database, so that the management command can be delivered quickly. Therefore, in the case of managing the enterprise public private network in conjunction with the integrated network service management system, the command to the exchange can automatically search for and process a specific operating terminal system, thereby reducing unnecessary repetitive access without operator intervention. As a result, the management command of the integrated network management system can be promptly transmitted to the exchange of the enterprise public private network in the form of an appropriate management message so that the operation and management of the switching system can be mutually open.
