KR20030015953A - Switching System Having Agent and Network Management Data Collection and Change Method Using There of - Google Patents

Abstract

PURPOSE: An exchange having an agent and a network management data collecting and a changing method using the same are provided to mount an agent module on the exchange, and to make the agent module directly access a database or call a necessary library to collect/change network management data, thereby flexibly collecting and changing the data. CONSTITUTION: When requesting a message of collecting or changing network management data, an agent module decodes the message transmitted from a manager, and analyzes what the manager wants(S10,S12,S14). The agent module accesses or updates the database, and calls a necessary library to collect or change data at the request of the manager(S16). The agent module encodes a result message including the collected or the changed network management data to a CMIP or an SNMP, and transmits the encoded message to the manager(S18,S20).

Description

Switching System Having Agent and Network Management Data Collection and Change Method Using There of}

The present invention relates to an exchange having an agent and a method for collecting and modifying network management data using the same, and more particularly, to an exchange having an agent capable of performing collection and change of network management data interspersed in the exchange at an exchange. It relates to a network management data collection and change method used.

In general, a Telecommunications Management Network is a network that provides a method of collecting, distributing, transmitting, and accumulating information related to operation, maintenance, and management of a communication network. A network element and actual network management It is composed of a manager in charge of and an agent.

As described above, the administrator delivers the management commands by the operator to the agents that are physically or logically divided through the data communication network using the Common Management Information Protocol (CMIP) or the Small Network Management Protocol (SNMP). It is responsible for generating useful network management information by collecting and evaluating the performance results and status reports of the exchange. The agent manages the same shape and state information as that of the exchange by using a managed object modeled by the object-oriented model of the exchange to be managed, and manages the request from the administrator. Obtain information or collect it directly from the exchange and pass it on to the administrator.

As shown in FIG. 1, in the related art, when the agent 20 is installed outside the exchange 10 to be managed and receives a request for collecting and changing data from the manager 30, the agent 20 receives a command requested from the manager 30. Changed to a command corresponding to an operator command and inputted to the exchange 10, and the exchanger 10 receiving the command from the agent 20 processes the command received from the agent 20 in the same manner as the command input by the operator. After that, the result is output to the agent 20. As described above, the agent 20 receiving the processing result from the exchange 10 extracts the necessary data from the result message received from the exchange 10 and transmits the extracted data to the manager 30.

As described above, the conventional agent should process the request command of the administrator in the form of an operator input command, unless there is a separate interface and processing module for agent processing at the exchange when collecting network management data of the exchange. After extracting the data requested by the administrator from the result message, the extracted data must be transmitted to the administrator, which complicates the process and reduces flexibility in collecting and changing network management data.

The present invention has been made to solve the above-mentioned problems, and the agent module is installed in the exchange to enable the agent module to directly access the database or call the required library to collect and change network management data according to the administrator's request. The purpose is to provide an exchange having a network and a method for collecting and changing network management data using the same.

Figure 2 shows the configuration of an exchanger with an agent according to the invention.

An exchange having an agent according to the present invention for achieving the above object is installed inside the exchange, and connected to the manager and operate in CMIP / SNMP, and when the network management data collection and change request from the manager is requested It is provided with an agent module that directly accesses or calls a required library to perform a function requested by the administrator, and transmits the result of the processing to the administrator.

On the other hand, the network management data collection and change method using an exchange with an agent according to the present invention, when receiving the network management data collection or change request message required for management from the administrator, by decoding the received message request of the administrator Analyzing the matter; Collecting or modifying network management data by directly accessing a database or calling a required library according to the analyzed administrator's request; And encoding a result message including the collected or modified network management data and transmitting the encoded result message to the manager.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to a switch having an agent according to a preferred embodiment of the present invention and a method for collecting and changing network management data using the same.

Figure 2 is a road showing the configuration of the switch having an agent according to the present invention, the agent module 130 is installed mounted inside the switch 100, the manager 200 and TCP (Transmission Control Protocol), UDP / IP (User) It works by connecting with CMIP or SNMP over Datagram Protocol / Internet Protocol.

As described above, the agent module 130 is configured to directly access the database 110 or the library 120, and upon receiving the network management data collection and change request from the manager 200, the agent module 130 is mounted in the switch 100. Accessing the database 110 directly or calling the required library 120 performs the function required by the manager 200, and transmits the processing result to the manager 200.

3 is a flowchart illustrating a method for collecting and changing network management data using an exchange having an agent according to the present invention.

First, when receiving a network management data collection or change request message required for management from the manager 200 operating in connection with CMIP or SNMP over TCP, UDP / IP, the agent module 130 receives the message received from the manager 200. After decoding, the manager 200 analyzes what the requirements are (S10, S12, S14).

Subsequently, a task of collecting or changing necessary network management data is performed according to a request of the manager 200 (S16).

In step S16, the agent module 130 accesses or updates the database 110, calls the necessary library 120, and collects or changes data that needs to be collected or changed according to a request of the manager 200.

As described above, after the network management data is collected or changed through the process S16, the agent module 130 collects or changes the network management data to transmit the collected or changed network management data to the manager 200. The resulting result message is encoded in CMIP or SNMP, and the encoded result message is transmitted to the manager 200 (S18 and S20).

An exchange having an agent of the present invention and a method for collecting and changing network management data using the same are not limited to the above-described embodiments, and various modifications may be made within the scope of the technical idea of the present invention.

According to an exchange having an agent of the present invention as described above and a method for collecting and changing network management data using the same, an agent module is installed in the exchange, and the agent module directly accesses a database or calls a required library at the request of an administrator. By collecting and changing the network management data, there is no need to process the request message received from the administrator in the form of an operator input command or extract the necessary data from the result message received from the exchange. Accordingly, flexibility in collecting and changing network management data can be improved.
