The present invention relates to a remote management system, and more specifically, by using a syslog (syslog) of the remote local Internet equipment in real time to recognize whether or not an error occurs by connecting to a console port through a separate network in the event of an error The present invention relates to a remote management system for remote local Internet equipment that improves Internet quality by reducing time and removing obstacles in advance through regular facility inspection through automatic inspection.

Recently, as more homes and businesses use the Internet, customers are demanding a faster and more comfortable Internet environment. To support this, the number of equipment managed by a telecommunications company is increasing.

However, the number of people who manage the equipment is limited, so if there is a problem with the Internet equipment, if it takes a lot of time from reception to action, there is a possibility that many problems such as protests from each family, financial damages of the company, and credit loss will occur. It is always inherent. Therefore, there is a need for a system that can monitor the status of a large number of devices in one place and handle them immediately when an alarm occurs.

Applicant (KT) is currently operating a number of network management systems for a specific purpose in order to perform a smooth function of the network performing a wide range of functions. IP networks are composed of various types of routers and switches, and the systems managing these devices are IP network management systems. Operators who manage the network monitor the network status through this IP network management system, and when a problem occurs, it solves the problem according to the work instructions accordingly.

However, it is true that the network management system up to now has been focused on the monitoring function that displays the data after the data is imported through the SNMP (Small Network Message Protocol) of the equipment. Therefore, there is a lack of tools that can systematically assist the operator in the process of recognizing a failure and immediately deal with the failure in real time.

Accordingly, an object of the present invention for solving the above problems is to improve the Internet quality by promptly handling the occurrence of a failure through remote management of the Internet equipment and removing the cause of the failure in advance.

Remote management system for the remote local Internet equipment of the present invention for achieving the above object is directly connected to the console of the remote local Internet equipment, the command from the operator terminal received through the remote management network that is a closed network Console server for controlling the Internet equipment according to; And receiving a system log from the Internet equipment to detect whether a failure occurs, and transmitting pre-stored instructions to the Internet equipment periodically to check whether there is an error and to deliver an alarm message to the operator terminal when an error occurs. Have a server.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a system configuration diagram showing the configuration of a remote management system according to the present invention.

The remote management system of the present invention includes an integrated management server 10, a console server 20, and an operator terminal 30.

The integrated management server 10 is provided with a syslog from the Internet equipment (router, switch, NAS, etc.) and the console server 20 whether the failure of the equipment and the connection between the equipment and the console server 20 The status is monitored in real time, and when an error occurs, and sends an alarm message to the operator terminal (30). And, the management server 10 receives and stores the equipment configuration information (config) from the equipment in a certain period (daily / weekly / monthly repetition / once) set by the operator and upload the new equipment configuration information to the equipment It performs automatic check function according to the preset check list every certain period set by the operator (daily / weekly / monthly repetition / once) and detects the symptoms of failure for each device in advance and notifies the operator to it. . In addition, the integrated management server 10 allows the operator to query the collected Syslog list, alarm list, fault occurrence history and action details.

The integrated management server 10 includes a web server 12, a syslog server 14, an automatic check server 16, and a database 18.

Web server 12, the operator log in to the operator terminal 30, the data necessary for system operation and remote management, such as facility information, various history information (failure history, system log list, alarm list, access history, etc.) and operation information It allows you to input and inquire and performs various statistical processing (facility status statistics, history statistics, subscription statistics, etc.) on the stored information.

Syslog server 14 collects the Syslog from the Internet equipment and the console server 20 and stores the Syslog in the database 18 and filters the collected Syslog to generate an alarm when a log above a certain level set by the operator occurs. Delivers an alert message (pop-up) to the operator terminal (30). In this case, the syslog server 14 may store all the logs from the devices or selectively store only logs above a specific level (backup level) set by the operator.

The automatic check server 16 accesses the Internet devices and backs up or uploads device configuration information (config) set in the Internet devices using tFTP / FTP, and transmits the pre-stored commands according to a schedule previously reserved by the operator. The system automatically checks the equipment for abnormalities by performing the specified tasks. That is, the automatic check server 16 performs a telnet connection with designated devices at predetermined predetermined periods and executes a pre-booked command to automatically check for abnormalities of the respective devices. And, the automatic check server 16 receives the operation process (automatic check history) of the equipment according to the command execution from the equipment and stores the details in the database 18, and if an abnormality is detected on the equipment operator's terminal Deliver to 30 and notify the operator.

The database 18 operates the remote management system such as various information collected from the integrated management server 10 (syslog, backed up equipment setting information, etc.), various data inputted from the operator (information reserved for automatic inspection, etc.). Save the data needed for. The database 18 has a three-tier structure, in which each server 12, 14, 16 and the operator terminal 30 are connected to each other through an intermediate medium (data service), which is middleware, without being directly connected. It supports multiple connections of the servers 30 and servers 12, 14 and 16 and allows each program to flexibly cope with database changes. In addition, it supports encryption and decryption of important data input and output.

The console server 20 supports the console port connection of the operator terminal 30 to each device connected to it through the multiport panel (MPP), so that the operator uses the operator terminal 30 to remotely connect the Internet equipment. Allows you to check their current operating status, control their behavior or restart the system. The console server 20 has a channel management function for displaying the accessor list and accessors with the current control right connected to each device, the function of managing the control right to input a preset control command when there are multiple accessors on the same device, It performs periodic check of console port connection status and manages redundant connection with same ID. At this time, the console server 20 first gives control to the first accessor, and allows other accessors to see only the contents of the connection, and checks the status of the console port (UP, DOWN, UNKNOWN) every minute, for example, DOWN. When a state occurs, the log (alarm message) is transmitted to the syslog server 14 of the integrated management server 10. And, if the console server 20 detects the connection to the same device with the same ID, and releases the previous connection and connects only the new connection effectively. In addition, the console server 20 is set to restart automatically when abnormal termination occurs to promote the stability of the system operation.

The operator terminal 30 is a client terminal for the integrated management server 10 and the console server 20, and accesses the integrated management server 10 to manage equipment access, system log alarm management, inspection history management, equipment operation management, and the like. Do this. In this case, the equipment access management is a function that allows the operator terminal 30 to perform a telnet connection to a specific device and receive a console accessor list for the connected device, and to send and receive control rights between accessors, and the syslog alarm management is integrated. Receives a Syslog alarm from the management server 10 and checks the contents of the alarm when it occurs, so that you can take action. Checking history management is a function that inquires syslog alarm history, fault history, automatic check history, etc., and executes necessary debug by telnet connection to abnormal equipment. Equipment operation management is the connection information with the equipment connected to the console server 20, the multi-port operation state between the console server 20 and the connected equipment, the list of the most recently connected equipment, equipment with high connection frequency, connected equipment This function allows you to check the information such as the command history that was executed in. In particular, the operator terminal 30 directly connects to the console service of the console server 20 through the remote management network, which is a closed network, when the telnet connection to the controlled Internet equipment is not possible due to the failure of the upper level of the Internet equipment to be controlled. As if you input commands to the console port in the field, you control the equipment from the remote place.

Figure 2 is a flow chart illustrating a procedure of receiving and taking a Syslog alert in an operation scenario of a remote management system according to the present invention.

When an event occurs (e.g., a failure of an internet device or a channel connection failure between the console server 20 and a device) occurs in the managed device (2-①), the device generates a log of the generated event. This syslog is transmitted to the syslog server 14 (2-②).

Syslog server 14 registers and stores the received log in database 18 and filters the received sylog, if the corresponding sylog is above the alarm level (grade) set by the operator (2-③), an alarm is issued. It generates and delivers an alarm message to all operator terminals 30 currently connected to the Syslog server 14 (2-④). At this time, when the same sylog is repeatedly received in a short time continuously from the corresponding equipment, the Syslog server 14 stores only the duplicate number and registers it as one log.

In the operator terminal 30 receiving the alarm message, an alarm window as shown in FIG. 3 is displayed on the screen (2-⑤). At this time, when a duplicate alarm occurs for the same Syslog, the number of "alarm duplication" is displayed at the top of the alarm window of FIG. And, if the operator wants to know the alarm contents in detail after recognizing the alarm occurrence through the pop-up alarm window, if you click "Shipmaster Information" at the bottom of the alarm window, the number for the equipment as shown in FIG. Show the chapter.

5 is an interface screen shown when an operator accesses the Syslog server 14 using the operator terminal 30, and the Syslog server 14 receives a system received from each device through an interface screen as shown in FIG. Display log messages and alarms. In FIG. 5, the "syslog" menu is selected, but the corresponding information may be inquired by the operator selecting the "alarm history" and "accessor list" items.

When the operator recognizes the alarm, the user interface screen as shown in Fig. 6 attempts to connect to the equipment that has an abnormality by telnet (2-⑥), and when the telnet connection to the corresponding equipment is possible, the corresponding equipment by using telnet. Send the command and execute it to recover the error (2-⑦).

At this time, if telnet access to the equipment is impossible, the operator terminal directly accesses the console service of the console server 20 through the remote management network, which is a separate closed network (2-⑧), through the multiport panel (MPP). After connecting directly with the equipment, input and execute the necessary command (2-⑨) to recover the occurrence of the equipment. Of course, it is possible to recover the abnormal occurrence by accessing the console server 20 directly through the remote management network without telnet access.

At this time, the alarm for the equipment is transmitted to all the operator terminals 30 that are currently connected to the Syslog server 14 as in step 2-④, so that a plurality of different operators for the same equipment is connected to the console server ( 20). In this case, since the same command may be repeatedly input for the same device, in order to prevent this, the console server 20 grants permission to input a command to only one user who first accesses the device for the same device, Visitors only grant the right to view the contents of the connection. In addition, when the continuous connection to the same equipment is made with the same ID, the console server 20 releases the connection between the existing operator terminal and the equipment and effectively connects only the new connection. At this time, the console server 20 notifies the previously connected operator terminal 30 that the channel connection is released by the same ID connection.

In the above-described step 2-③, the alarm level for the syslog may be set using the "environmental setting" menu on the syslog interface screen as shown in FIG. 7 and the path level thereof.

8 is a flowchart illustrating a process of executing an automatic check reservation among operating scenarios of a remote management system according to the present invention.

The operator directly connects to the automatic check server 16 by the operator terminal 30 or through the web server 12 and uses the interface screen as shown in FIG. 9 to check the automatic check item (job name) and the type (cycle) of each item. , Schedule the execution time and repetition cycle in advance (8-①). The reservation information thus set is stored in the database 18, and all the reservation information stored can be checked through the interface screen as shown in FIG. 10 by accessing the automatic check server 16, and the information can be added / modified or a specific task can be immediately performed. Can be run.

After the reservation is completed, when the scheduled time arrives, the auto-check server 16 connects to the Internet devices via telnet and transfers the reserved command to perform a specific task to automatically check whether the corresponding device is in normal operation or the like ( 8-②). At this time, the auto-check server 16 stores all details of the command execution through the telnet in the database 18, and the future operator selects the "telnet execution" menu on the interface screen of FIG. You can check the details.

If it is confirmed that there is an error in the inspection target equipment during the execution of the automatic inspection (2-③), the automatic inspection server 16 stores the details of the occurrence in the database 18 and generates an alarm to the operator terminal 30. Deliver alarm message (8-④).

The operator terminal 30 receiving the alarm message pops up an alarm window as shown in FIG. 3 so that the operator can recognize it (8-⑤).

When the operator recognizes the alarm, he / she attempts to connect to the device that caused the problem by using telnet (8-⑥). If telnet connection is possible to the device, the operator sends and executes the command to the device by using telnet. Restore (8-⑦).

At this time, if telnet access to the equipment is impossible, the operator terminal directly accesses the console service of the console server 20 through a remote management network, which is a separate closed network (8-⑧), through a multiport panel (MPP). After connecting directly with the equipment, input and execute the necessary command (8-⑨) to recover the occurrence of the equipment. Of course, it is possible to recover the abnormal occurrence by accessing the console server 20 directly through the remote management network without telnet access.

Even if no abnormality is found at the moment of checking the equipment in step 8-③, if the possibility of an abnormality is detected while the operator reviews the execution of the automatic inspection afterwards, it is performed through the above-described steps 8-⑥ to 8-⑧. By taking measures, abnormal occurrence can be prevented in advance.

12 is a flowchart illustrating an A / S process through the reception of an individual line fault in an operation scenario of a remote management system according to the present invention.

When a customer report is received or an operator detects an abnormality while monitoring the status of the equipment (12-①), the operator inputs and executes a command by connecting to the equipment where the abnormality occurred through telnet (12-②), Connected to the console server 20 through the remote management network (12-③) and connected directly to the equipment through the multiport panel (MPP) and then input and execute the necessary commands (12-④) to cause the abnormality of the equipment. Will recover.

As described above, the remote management system of the present invention collects the Syslog from the Internet equipment or remotely detects the abnormality of the Internet equipment by using a scheduled automatic check, and when the problem occurs, the remote management network that is a telnet or a closed network. By executing commands on the equipment, you can improve the Internet quality by recovering from failures and eliminating probable causes in advance.
