METHOD AND APPARATUS FOR IMPLEMENTATION FUNCTION OF REMOTE NETWORK MONITORING IN HIGH SPEED ROUTER, AND STORAGE MEDIUM FOR RECORDING PROGRAM THEREOF}

The present invention relates to a remote monitoring function in an 80 Gbps high-speed router system, and more particularly, a local operator and an external remote network manager can independently access the same data on both sides while performing a network monitoring function. A method and apparatus for implementing a remote network monitoring function of a high speed router system for performing management, and a recording medium recording a program for performing the same.

According to the Internet Architecture Board (IAB) of the United States, published in Request for Comments (RFC) 2819, which published research, suggestions, technology, and findings about the Internet, Remote Network Monitoring This is accomplished through the periodic collection and processing of collected data by polling and response from the top level network manager to the underlying network probe.

Currently implemented network monitoring has one remote monitoring probe (RMON probe) for each subnet, and after collecting the data for network monitoring from each RMON probe, it sends the collected data to the upper network manager. Consists of.

The upper network manager processes the data collected from each probe to indicate the network status of each subnet and the entire network.

At this time, the data necessary for network monitoring is RFC It is defined as RMON Management Information Base (MIB) of MIB-II of 1213. The RMON-I MIB is classified into 10 groups.

Remote network monitoring consists of the results obtained by combining the ten groups of data according to the network situation. As described above, data for network monitoring to be provided to the upper network manager is collected and stored by the RMON probe.

For example, the information on each subnet collected by the Network Management Server (NMS) can be divided into statistics groups representing overall statistics for each subnet, history representing the amount of data per hour on the subnet, and hosts from each host. Information about a host group indicating statistics of a group and a matrix group indicating a data exchange amount between hosts.

As described above, the RMON probe performs a function of managing collected data in addition to collecting data to be provided to the manager.

As a network monitoring technology known so far, Korean Patent Publication No. 2000-42940 published on July 15, 2000, "A device and method for remote monitoring of network equipment" is to reduce the time delay problem caused by the remote monitoring process. We propose a method to reduce the packet occupancy time by the remote monitoring process by copying the received packet to the memory shared by the lower task and the Ethernet driver, and to reduce the performance impact of other processes by the remote monitoring process by copying the packet. As described above, the conventional network monitoring technology is mainly related to the technical aspects at the lower level of the hardware side, and no processing technology such as data management inside the RMON probe has been considered.

An interface management unit 121, a remote monitoring main processor 122 for receiving a message input from the operator matching function unit 121 and the SNMP matching function unit 125 to be described later, and performing a corresponding function; The remote monitoring Simple Network Management Protocol function (hereinafter abbreviated as SNMP) unit 123 for processing a command from a remote operator is interchanged with the database client function mounted in the remote monitoring function and a message. Remote monitoring for storing data or transmitting the stored data to the remote monitoring main processing unit 122 and the SNMP function unit 123. It is connected to the Itabase (hereinafter abbreviated as RMDB) 124, to the remote operation terminal 140 of the remote location, SNMP matching function 125 for transmitting and receiving the remote monitoring message, and the Ethernet interface card 132 And a remote monitoring interface unit (hereinafter abbreviated as RMONI unit) 126 which holds statistical information of input / output data.

That is, the remote network monitoring apparatus in the high-speed router system according to the present invention is composed of a process for processing a message from the local operator, and a process for processing a message from the remote operator.

As shown in FIG. 1, the operator matching function unit 121, the remote monitoring main processing unit 122, the SNMP function unit 123, the RMDB 124, and the SNMP matching function unit 125 are described above. In the high speed router system, the routing processor 120 is provided, and the remote monitoring interface unit 126 is implemented in the line processor 131 of the line card 130.

Referring to the remote monitoring function implemented by the above.

The operator matching function unit 121 and the SNMP matching function unit 125 receive messages from the local operation terminal 110 and the remote operation terminal 140, respectively, and the remote monitoring main processing unit 122 and the SNMP function unit 123. To pass.

And, the remote monitoring main processor 122 and the SNMP function 123 performs the request of the received monitoring-related messages, respectively, if you want statistical information in the received message, the statistics table to the remote monitoring interface unit 126 After the data counter value of the (statistics table) is requested, the received value is transmitted to the operator (local operation terminal 110 or remote operation terminal 140).

In addition, when performing an information request message other than statistical information, a request is made to the RMDB 124 for data, or a message is transferred to the RMDB 124, and the RMDB 124 processes the requested message to provide the corresponding data. Save it.

2 is a structural diagram illustrating a data exchange method implemented in a remote network monitoring function according to the present invention. Reference numeral 201 denotes a plurality of remote monitoring applications (hereinafter referred to as RMON APPs) executed in the local operating terminal 110 and the remote operation terminal 140, and 202 denotes a plurality of connected to the plurality of RMON APPs 201, respectively. Is an RMDB client, 203 is an RMDB server, and 204 is a repository where data is stored.

As shown in FIG. 2, since a plurality of RMON APPs 201 exist when performing remote monitoring, as shown in FIG. 2, the RMDB client 202 and the RMDB server 203 have a relationship of n: 1. .

The RMON APP 201 is a process that performs a unique function of remote network monitoring and performs a function of history, alarm, and event. First, the RMON APP 201, which is set up by an operator or a remote network manager and performs a specific remote network monitoring function, stores the processing result or retrieves necessary data according to the function execution, and configures the corresponding data to configure the RMDB client. Forward to 202.

The RMDB client 202 reconstructs the data received from the RMON APP 201 into a message exchanged between the RMDB servers 203 and then transmits a message composed of the RMDB servers 203.

The RMDB server 203 performs a function corresponding to the received message. When the received message requires the retrieval of data, the RMDB server 203 retrieves the data in the data store 204 and returns the result message to the corresponding RMDB client 202. In case of storing the result of the processing, the data is stored in the storage 204 according to the message received from the RMDB client 202.

Accordingly, the RMDB client 202 transmits a message received from the RMDB server 203 to the RMON APP 201, and the RMON APP 201 transmits the result accordingly to the local operation terminal 110 or the remote operation terminal 140. To be delivered to.

FIG. 3 illustrates a structure of a message exchanged between the RMDB client 202 and the RMDB server 203 of FIG. 2, and a mode 301 is a part representing a command to be performed in the RMDB server 203. 301 may be a store, retrieve, delete, or the like. The TYPE 302 is used to select a type of data. The TYPE 302 indicates which group of the RMON MIB is defined as the TYPE managed by the RMDB server 203. For example, statistics group, history group, alarm group, host group, and so on. The DBNAME 303 indicates a DB name to be accessed. In addition, REFID_1 304 and REFID_2 305 are used to access a specific data term in the accessed DB. The REFID_2 305 is not used according to the type of the TYPE 302. And, APP_ID 306 represents the ID of the client accessing the DB. Finally, the DATA unit 307 is used to store or retrieve the actual data.

For example, if a message is configured as a storage in MODE 301, a history in TYPE 302, H100 in DBNAME 303, 1 in REFID_1 305, and 2 in REFID_2 305, The RMDB server 203 accesses data whose group type is history and whose DB name is H100, and stores the data of the term having REFID_1 1 and REFID_2 2 as data field data. Here, since type 303 is history, REFID_1 304 indicates historyControlIndex and REFID_2 305 indicates historySampleIndex. By composing this message, data of RMON-1 MIB group can be managed efficiently by using database server function and database client function.

4 and 5 are flowcharts showing the operation procedure of the high-speed router system according to the present invention configured as shown in Figure 1, Figure 4 is a monitoring process by the local operator Figure 5 is a monitoring process by the remote operator Indicates.

Since the flowcharts of FIGS. 4 and 5 are almost similar, FIG. 4 will mainly be described in the following description, and FIG. 5 will only describe differences from FIG. 4.

According to FIG. 4, in order to perform a remote network monitoring function of a local operator, after the remote monitoring main processor 122 shown in FIG. 1 is generated, the remote monitoring main processor 122 is configured to receive the local operator from the local operator in a standby state. Wait for command input (401).

The command of the local operator is input through the local operation terminal 110, and is transmitted to the remote monitoring main processor 122 through the operator matching function 121.

Accordingly, when the command message from the local operator is received through the operator matching function 121 (402), the remote monitoring main processor 122 determines whether the received message is a message about an information request (403). .

If it is determined that the message is about the information request, it is determined whether the information requested by the received message is statistical information (404).

In this case, when the information requested in the received message is statistical information, the counter information request message is transmitted to the RMONI unit 126 (405). As a result, a result message is received from the RMONI unit 126 (406), and then, based on the received data, output data for outputting a message to the terminal 110 of the corresponding local operator is formed (407). To transmit the output message to the local operation terminal 110 via the operator matching function 121 (408). Then, it enters the standby state for processing the next received message.

In step 404, if the received message does not require statistical information, the information request is performed to the RMDB server 203 (411), and the result thereof is returned from the RMDB server 203. Received 412, as in the case of the statistical information request, the output message is configured and then output to the terminal 110 of the local operator via the operator matching function 121 (407, 408).

In step 403, if the received message is not an information request message, the corresponding function requested by the received message is performed (409), and the processing result is stored in the RMDB 124 (410). .

Then, the processing result is configured as output data as described above, and is output to the terminal 110 of the local operator through the operator matching function 121 (407 and 408). Then, it enters the standby state to process the next received message.

The function performed by the remote monitoring main processor 122 refers to a function such as history and alarm.

Next, FIG. 5 is a flowchart showing a remote monitoring process by the remote operator, and the remote monitoring process by the remote operator replaces the SNMP matching function unit on behalf of the operator matching function unit 121 and the remote monitoring main processing unit 122. It is implemented in the 125 and the SNMP function 123, similar to the remote monitoring process of the local operator shown in FIG.

That is, like the remote monitoring main processing unit 122, after the SNMP function unit 123 is generated at initialization, it waits for receiving a message from the remote operation terminal 140 in the standby state (501).

Receiving the message from the remote operation terminal 140 is made through the SNMP matching function unit 125. When the message of the remote operation terminal 140 is received from the SNMP matching function unit 125 in the standby state (502), The request message of the received remote network management manager is processed, in which the processes 503 to 506 and 509 to 512 are the same as the request message processing processes 403 to 406 and 409 to 412 of the local network manager.

When the processing of the request message is completed as described above, an output data related to the processing is configured (507) and transmitted to the remote operation terminal 140 of the remote network management manager through the SNMP matching function 125.

According to the configuration and operation described above, the present invention provides a network management by the local operator and the external network manager independently, and integrated management of the monitoring data generated by the local operator and the external network manager by the database server function In addition, the data generated by the local operator can be accessed by remote network administrators. In addition, when the results processed in each process need to be accessed by another process for a plurality of remote monitoring processes There is an excellent effect to implement efficient data management.
