Abstract

PURPOSE: A method for initializing a gateway by using state information in a CORBA-based network management system is provided so that a connection setup time and a network load can be reduced by simplifying a connection setup process between an administrator and the gateway. CONSTITUTION: An administrator initializes connection to a gateway(301), and transmits a state information file to the gateway(302). The gateway compares its state information file with the received state information file(303). When there is the difference between the state information and the received information, the received information file is renewed to the state information file of the gateway(304). In addition, proxy management objects of the gateway are generated by using management object information of the state information file, and named according to management information(305). Thereafter, the state information file of the gateway is transmitted to the administrator(306). The administrator compares its state information file with the received information file(307). When there is a difference, the administrator renews its state information to the state information file of the gateway(308). It is thus possible to reduce a number of information transmission steps between a plurality of gateways and an administrator into two in a connection setup process.

Description

Gateway initialization using status information in COVA-based network management system configuration {METHOD FOR INITIALIZING GATEWAY USING INFORMATION OF STATE IN CORBA BASED NETWORK MANAGEMENT SYSTEM}

The present invention relates to a method of initializing a gateway using state information in a CORBA (Common Object Request Broker Architecture) based network management system and a computer readable recording medium recording a program for realizing the method. In the configuration of COBA-based network management system, the connection setup process is simplified by using the status information file of the manager and the gateway for the connection setup between the manager and the gateway to perform a quick connection setup, reduce the communication load on the network, and abnormal The present invention relates to a method of initializing a gateway that can be restored to a previous state in connection with disconnection, and to a computer-readable recording medium having recorded thereon a program for realizing the method.

In the conventional method of constructing a COVA-based network management system, an administrator generates one proxy management object in the gateway for a number of management objects of a network device to be managed. At this time, for each proxy management object creation and naming registration, the reference must be returned in connection with the manager each time. This management object registration process requires an excessive network load on the manager and the gateway as the network size increases and the number of management objects of the network equipment increases. In particular, the connection establishment process for each of the managers and gateways should be performed again at abnormal termination. .

1 is a configuration example of a general COBA-based network management system, a structure of a COBA-based network management system having a gateway system between the COBA-based manager and the network device actually managed.

First, the manager 101 initializes with the gateway 102 on the basis of various information about the managed network before performing the management action. Then, through the gateway 102 to approach the agent 103 of the network equipment to be managed to perform various management operations.

FIG. 2 is a flowchart illustrating an initialization and management operation of a gateway in a conventional COVA-based network management system. FIG. 2 illustrates a process of creating and naming registration of each management domain, proxy delegate, and proxy management object when establishing a connection between an administrator and a gateway. The flow chart is shown.

First, the administrator initializes the connection with the gateway (201), and sets the management domain for the managed system to be managed by the administrator in the gateway. At this time, the administrator searches for the management domain in the gateway (202), if it is necessary to create a new management domain to create a management domain, and performs naming registration (203). By searching for proxy delegates belonging to the management domain created in the gateway (204), the administrator generates a proxy delegate to be managed as needed and registers it with naming associated with the management domain (205).

When a proxy delegate is created, it creates all proxy managed objects managed by that proxy delegate. First, the administrator searches for a proxy management object in the gateway (206), and if a new proxy management object needs to be created, the manager creates a proxy management object and registers it with a naming related to the proxy delegate (207).

If there is more registered proxy management object (208), if the proxy management object needs to be generated for all the management objects for the management target, the proxy is repeatedly performed from the creation process (208).

When the proxy management object generation process for one proxy delegate is finished, it is determined whether there are more delegates to be managed (209), and if there are more delegates to be managed, the gateway repeats from the proxy proxy creation process (204). Perform. Check if there are more registered administrative domains (210), if additional administrative domains are needed, repeat the process of creating administrative domains (202), and create proxy delegates belonging to the administrative domain and proxy management object for each proxy delegate. You should repeat the creation of Such initialization requires continuous exchange of information between the manager and the gateway, and especially when managing a large number of managed systems or managing a large network, a large performance degradation occurs during the connection setup process, and the network load is increased. . When the connection setup process is completed, the manager performs a management operation on the management target (211).

That is, the related art requires an excessive network load for the creation of each management object and the naming registration for establishing the connection between the manager and the gateway, and has to perform the connection establishment process again upon abnormal termination between the manager and the gateway. In particular, there was a problem that takes a lot of time to establish a connection when managing a large network or network equipment.

The present invention has been made to solve the above problems, and in the configuration of the COVA-based network management system, the connection setup process between the manager and the gateway is simplified by using a status information file of the manager and the gateway to simplify the connection setup process. The purpose of the present invention is to provide a method of initializing a gateway that reduces the communication load on the connection and the network and restores it to a previous state for abnormal disconnection, and a computer-readable recording medium that records a program for realizing the method. .

The present invention also provides a network management system having a processor, comprising: a first function of an administrator for transmitting his / her status information to a gateway; A second function of initializing the gateway by using the state information transmitted by the gateway; A third function of updating state information of the gateway according to a state change when performing a management operation; And a fourth function of updating the status information of the manager as necessary by using the status information of the gateway when the network management system ends.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a flowchart illustrating an initialization and management operation of a gateway using state information in a COBA-based network management system according to the present invention. FIG. 3 is a diagram illustrating an example of generating and naming proxy management objects of a gateway using a state information file of an administrator and a gateway. A flowchart of a method of updating status information when a status change occurs while performing a registration process and performing a management operation is shown.

First, the manager initializes the connection with the gateway (301). Then, the administrator's status information file is transmitted to the gateway (302). The gateway compares its own status information file with the manager's status information file transmitted (303), and if the contents of the status information are wrong, it is updated with the gateway's status information file (304), and is applied to all managed objects in the status information file. Proxy management objects are generated in the gateway using the information about the server and naming registration is performed according to the management information (305). The gateway transmits the state information file of the gateway to the administrator (306).

The administrator compares his state information file with the transmitted state information file (307) and if the state information is changed, updates his state information with the state information file of the gateway (308), naming and proxy management objects. Construct the references (309).

This process is the connection establishment process of the gateway and the manager, the information transfer process between the numerous gateways and the manager in the existing connection establishment process is reduced to two information transfer (302, 306). That is, the process of generating and managing naming registration of the proxy managed objects of the gateway is performed at once using the state information file internally of the gateway system (305), thereby improving performance. In case of abnormal termination between the gateways, it is possible to restore the previous state by using the state information of the gateways (303, 304, 305).

In operation 310 of the management operation, it is determined whether the change of the state information has occurred in the gateway system (311). If the change of the state information occurs in the gateway system, the state information file of the gateway is updated (312). By using this, even in abnormal termination, the previous state can be restored using the state information file of the gateway.

At the end of the management task, the gateway delivers its own state information file to the administrator (313), and the administrator can update its own state information file (314) as necessary. The manager, the gateway, and the delegate system terminate each connection to terminate the management system (315).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawing.

The present invention as described above, in the COBA-based network management system can simplify the connection setup process between the manager and the gateway, thereby reducing the connection setup time for information transmission between the manager and the gateway and can reduce the load on the network It works.

In addition, the present invention can eliminate the retry of the connection establishment process according to the abnormal disconnection between the manager and the gateway, and can easily recover to the state before disconnection, especially in a large network or network equipment Fast connection setup and recovery can be achieved, which can improve the performance and reliability of COVA-based network management system.
