Description

Management system of communication network system and its management method {Management system of network system and method therefor}

The present invention relates to a management system and a management method of a communication network system constructed using the TCP / IP protocol, and more particularly, a management system composed of a control management unit and an agent of a managed resource, and performing management using SNMP; It relates to a management method thereof.

The management system or enterprise management system (EMS) of a communication network system constructed using the TCP / IP protocol manages communication network resources mainly by using a simple network management protocol (hereinafter referred to as SNMP), and a service application. It also manages the application server on which the (service application) operates and the application mounted on the application server.

In other words, SNMP is a useful protocol for determining whether the network resources constituting the communication network or the computer hardware constituting the service are operating normally.

In general, a management system that manages a communication network system by performing a fault detection of the system and collecting performance values for each managed item related to the equipment by using such an SNMP includes a control management unit of a management server and an agent of a managed resource ( It has a management system composed of agents.

1 is a view schematically showing a structure of a management system using SNMP in general.

The management server 10, which is a computer on which the control management unit 100 is installed and operated, is composed of a main memory device, an input / output device, and a central processing unit, and the control management unit software is installed.

Each of the managed resources 20, 21, 22..., The management server 10 and other managed resources 20, 21, 22..., Via a TCP / IP-based communication network for communication with the control management unit 100. Connected with In addition, the agent 200 is installed and operated for each managed resource 20, 21, 22.

FIG. 2 shows a relationship between the control management unit 100 of the management server 10 and the agent 200 of the managed resource 20 in the management system structure of FIG. 1.

The control manager 100 may transmit a specific message to the agent 200, measure a state of a resource to be managed, receive the measurement information, or change the state.

There are two main management methods used by such management systems. First, the control management unit performs all operations, and the agent is a control management centralized method that simply transmits the management information data to the control management unit at the request of the control management unit. The second is to give some intelligence to the agent, When defined information exceeds or falls below the threshold, it is an agent-distributed method that automatically reports the contents to the control management.

In the case of centralized control management, the relationship between the control management agent and the agent is that the control management communicates with all agents for the exchange of management information data between the control management agent and the agent, and judges whether the information transmitted from all agents is faulty and performance. Operation, such as exceeding a threshold of a value.

In the case of agent distributed type, the agent has information about failure or performance related threshold in advance and if any abnormality occurs, it reports it to the control manager voluntarily.

As in the case of the control management centralized method, when the control management unit commands all agents and instructs data collection to receive information, the control management unit periodically sends data extraction and transmission / reception commands to all agents. It is necessary to determine whether there is an abnormality in the received data and the detected and transmitted data. Therefore, the operation burden of the control management unit is increased, and sequential polling command delivery to the agent is delayed. It may not be possible to collect.

In addition, like the agent-distributed method, the intelligent decision function is provided to the agent to actively detect management information data from the management target resource, determine the management information data, and transmit it to the control management unit, or all detected management information data. In the case of transmitting the control to the control management unit, there is a case that the performance of the managed resources due to excessive computational burden on the agent, or the insolvency of the management system accordingly occurs.

As described above, in the conventional communication network or service management systems, since the control manager has a heavy computational burden, it takes a long time to detect a management item for a managed resource, or a management target in which an agent is installed due to excessive task performance of the agent. There are problems such as an increase in resource load.

The technical problem to be achieved by the present invention is to provide a management method of a communication system capable of distributing the computational load between the control management unit and the agent in an appropriate form for the entire management system and ensuring stable operation of the agent.

Another technical problem to be achieved by the present invention is to provide a control management unit for instructing management item detection and determining a management item detection result by distributing the computational burden to an agent on an appropriate scale.

In addition, another technical problem to be achieved by the present invention is to reduce the operational burden of the control management unit by reducing the operation load of the control management unit by serving to propagate the command delivered by the control management to other neighboring agents. It is to provide agent that can be made.

The management command may include a management item and a delivery order of agents determined based on the communication state information processing command for determining whether each agent has an abnormal communication state.

The communication status information processing command may be transmitted from the control manager to the second agents sequentially from the first agent to the neighboring second agents so that the third agent may report to the control manager.

If the agent that has received the communication status information processing command cannot transmit to the neighboring agent, the communication failure information and the communication status information processing command of the neighboring agent are directly transmitted to the control manager, and the control manager cannot communicate. A new communication state information processing command can be transmitted to the agent and the neighboring agent.

The control manager may change the delivery order such that the management command is directly transferred from the previous agent of the incapable agent to the subsequent agent of the incapable agent.

The communication network system may include a plurality of communication network groups including the first agent, at least one second agent, and a third agent.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention. Like parts are designated by like reference numerals throughout the specification.

First, a management system of a communication network or a communication system operating based on a TCP / IP communication protocol according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 6.

3 is a view showing a schematic configuration of a control management unit 100 according to an embodiment of the present invention.

The control manager 100 includes a control manager 110, a management information communication unit 120, a DB manager 130, a configuration manager DB 140, a failure manager DB 150, and a performance manager DB 160. .

The control manager 110 controls the operation of each functional block of the control manager 100 collectively.

The management information communication unit 120 performs a function of exchanging management information with the agent 200. The control management unit 100 issues a command to or receives a report from the agent 200 using the management information communication unit 110.

The DB manager 130 plays a role in managing the input / output and data of the configuration management DB, the failure management DB, and the performance management DB.

The configuration management DB 140 may include information related to physical or logical topology information of the managed resource 20 managed by the control management unit 100, characteristics of forming a managed resource such as the type of the managed resource 20, and the like. Save it.

The failure management DB 150 plays a role of storing information about a failure in each managed resource.

Performance management DB 150 serves to store information about the performance of each managed resource.

4 is a diagram illustrating a schematic configuration of an agent 200 according to an embodiment of the present invention.

The agent 200 includes a control manager control unit 210, an agent management information communication unit 220, an agent DB manager 230, and an agent configuration management DB 240.

The control manager 210 controls the operation of each functional block of the agent 200 collectively.

The agent management information communication unit 220 receives a command through the communication with the control management unit 100 or reports the state of the managed resource to the control management unit.

The agent DB manager 230 plays a role in managing input / output and data of the agent configuration management DB 240.

The agent configuration management DB 240 stores routing information, status information of managed resources, and the like.

Next, an operation relationship between the control management unit 100 and the agent 200 will be described.

First, the Internet Control Message Protocol (ICMP) is used to determine whether the management target resource 20 is normal.

That is, the control manager 100 determines whether the management target resource 20 is normal by using the ICMP request message ECHO_REQUEST and the ICMP response message ECHO_REPLY of the ICMP protocol.

The management information communication unit 120 of the control management unit 100 transmits an ICMP request message (ECHO_REQUEST) to the agent management information communication unit 220 of the agent 200. Upon receiving the ICMP request message (ECHO_REQUEST), the agent management information communication unit 220 checks the status information in the agent configuration management DB 240 through the agent DB management unit 230, and when it is operating normally, the ICMP received from the communication network interface. The normal ICMP response to the request message is sent to the management information communication unit 120.

In addition, the agent 200 transmits whether the hardware or application of the management target resource 20 is normally operated or the like to the control management unit 100 or receives the request of the control management unit 100 and the operation of the computer hardware or the application. It is used to change information related to the state of computer hardware or application which is predefined and promised.

In the use of the ICMP protocol by the control management unit, compared to other tasks performed by the control management unit 100, it is very simple to periodically check the transmission and response of the ICMP message for the corresponding service resource. In the case of managing thousands of managed resources 20, when performing a polling method of transmitting ICMP messages to the corresponding number of agents 200 sequentially and waiting for a response thereto, the control management unit ( 100) the load is excessive.

5 is a view schematically showing a relationship in which management information communication is performed between the control management unit 100 and the plurality of agents 200 according to an embodiment of the present invention.

That is, in this embodiment, the control management unit is responsible for detecting an error in the presence or absence of a failure of the communication network between the control management unit and the agent using the ICMP message. Rather than checking whether each node constituting the node is in a normal state, the adjacent agent uses a method of sequentially acting as a control management unit for another adjacent agent.

In FIG. 5, in the case of a communication network to which a very large number of managed resources are connected, the entire communication network is divided into several network groups. Each network group consists of the number of specific agents whose control management can receive one status report. The control manager manages the management information routing table of each network group separately. In this embodiment, four agents 200-1 to 200-4 form one communication network group by way of example.

First, the control management unit 100 receives the first command of its own in its own routing table in order to check a specific management target item indicating the state or performance of the managed resource belonging to the first communication network group ( 200-1), a corresponding command, for example, an ICMP request message. Upon receiving the status check request message, the agent 200-1 checks the status of the corresponding managed target resource and reports the status information to the control management unit 100 instead of reporting the status information to the control management unit 100. Delivers a status check request message to (200-2).

Similarly, the agent 200-2 checks the status of the corresponding managed resource and if it operates normally, the agent 200-2 does not report the status information to the control management unit 100, but the neighboring agent 200-3 stored in the internal routing table. Send status check request message

Finally, the agent 200-4 at the end of the routing path transmits the management item accumulation data in which the management item data of the last agent is accumulated from the first agent to the control management unit 100 again. The control management unit 100 receiving the management item accumulation data receives the data, extracts management item information for each agent recorded from all agents, and determines whether there is a failure or stores and stores data.

The same method as the first communication network group is applied to the n-th communication network group.

As such, the control management unit 100 instructs the first agent 200-1 to detect the management information data required and then performs other tasks in parallel until receiving the result data from the final agent 200-4. Since it can reduce the computational burden of the control management unit, it is possible to prevent work delay due to the computational burden.

In addition, the agent not only prevents the performance degradation of the managed resource itself, which may be caused by granting excessive functions, but also makes a decision and command whether to detect and transmit information on specific management items. Compared to the spontaneous detection and transmission of agents, there is an advantage in that management item information is detected at the most appropriate time in terms of the operation of the entire management system.

Next, a management method of a communication system according to the present invention will be described in more detail with reference to FIGS. 6 and 7.

6 is a flowchart illustrating a process of confirming state information whether an agent can communicate with an adjacent agent in a method of managing a communication system according to an exemplary embodiment of the present invention.

In the communication system management method according to an embodiment of the present invention, first, the control management unit 100 checks the status information of each agent in order to determine whether the agent can communicate with the neighboring agent. An example of using the ICMP ECHO_REQUEST and ECHO_REPLY messages as a command for checking the status information will be described. In addition, in the management method according to the embodiment, when the control management unit 100 confirms the status information that the abnormality occurs for a specific agent, the same status information check command to the first agent issued to the next agent of the agent having the abnormality After sending down, check the status information of the agent continuously.

First, the control management unit 100 checks the radio wave path recorded in the configuration management DB 140 to check the status of the agent located at the beginning (S100). That is, the propagation path of the agents starts from the agent 200-1 and proceeds to the agent 200-4 via the agent 200-2 and the agent 200-3.

Next, the control management unit 100 transmits ICMP ECHO_REQUEST to the first agent 200-1 (S100).

When the control management unit 100 confirms that the first agent 200-1 is not abnormal, the control management unit 100 starts the process of checking the status information of the agent 200-2 neighboring the agent 200-1. Send a command to (S200).

The first agent 200-1 transmits a request for reporting status information to the next agent 200-2 in charge thereof using a routing table stored in the agent configuration management DB 240 (S300).

The agent 200-1 waits for a status check response from the agent 200-2 for a predefined time (S400).

When the agent 200-1 receives the status check response from the agent 200-2, the agent 200-1 sends the status check command of the next agent 200-3 to the agent 200-3. (S410).

The agent 200-2 receiving the status check command of the next agent 200-3 determines whether the next agent 200-3 is present based on the agent configuration management DB 240 (S420).

If the next agent 200-3 exists, the process returns to step S300 again and repeats the subsequent management steps.

If the next agent 200-3 does not exist, that is, if the agent 200-2 is the last agent in the propagation path, the agent 200-2 checks the path of the control management unit for the presence or absence of abnormal status information. Report to the control management unit 100 that all the agents present in the complete has been performed (S430).

On the other hand, if the agent 200-1 does not receive a status check report from the agent 200-2, the agent 200-1 abnormally manages the resource 20 managed by the agent 200-2. It is determined that this has occurred, the agent 200-1 immediately reports the abnormality of the agent 200-2 to the control management unit 100 (S500).

Next, the control management unit 100 registers the state of the managed resource 20 managed by the agent 200-2 to the failure DB 150 as a failure state such as communication failure (S600).

Next, the control management unit 100 is the agent 200-3 located next to the second agent 200-2 in the position on the path for checking the status information or whether the agent 200-2 is the last agent Determine (S700).

If it is not the last agent, the process returns to step S100 and the control management unit 100 instructs the agent 200-3 to report the status information, and repeats the subsequent steps.

If it is determined that the agent 200-2 has occurred as the last agent, the status information reporting procedure ends.

Through this process, the control management unit 100 recognizes that there is a failure state such as communication failure due to an abnormality in the management target resource managed by the agent 200-2.

The management process of the following communication system is performed in consideration of a failure state such as communication failure due to an abnormality in the managed target resource managed by the agent 200-2.

FIG. 7 is a flowchart illustrating a method of managing a communication system in a state of having failure information performed in FIG. 6 in order.

First, the control management unit 100 reads the routing table of the configuration management DB (140) managed by itself to read the information of the first agent of the propagation path to which the status check command is transmitted (S100).

In step S600 of FIG. 6, the control manager 100 reads the information related to the failure related status recorded in the failure management DB 150, compares the current status information of the failure with the contents of the routing table, and generates a current failure. The control management unit 100 grasps the information about the management target resource that cannot perform the command and the agent (200-2) for managing it (S200).

The control management unit 100 updates neighboring agent information stored in the agent configuration management DB 240 of the agent 200-1, which transmits a command to the agent 200-2, which currently has a failure. That is, the control manager 100 notifies the agent 200-1 that the agent 200-3 is adjacent to the agent to transmit the command (S300).

The agent 200-1 updates the target agent for command delivery to the agent configuration management DB 240 from the agent 200-2 to the agent 200-3 (S400).

The control manager 100 transmits a management item detection packet of a specific management item AAA (point to a specific management target item, for example, a server CPU utilization rate, etc., hereinafter referred to as AAA) to the agent 200-1. (S500).

After transmitting the management command to the agent 200-1 in this way, the control management unit 100 may perform other operations until the final report packet arrives from the agent 200-4, which is the last agent, so that the control management unit proceeds. It can greatly reduce the computational burden.

Next, the agent 200-1 receives the management item detection packet and recognizes that it is a detection request of the status information for the management item called AAA, and then reads the status information of the AAA management item of the managed resource that is being managed by the agent. Attached to the management item detection packet received from the control management unit (S600).

Agent 200-1 checks the neighboring agent to which the command should be delivered from the routing table (S700).

When it is confirmed that the neighboring agent to deliver the command is the agent 200-3, the management item detection packet to which the status information of the agent 200-1 is attached is transmitted to the agent 200-3 (S710).

Returning to step S600, the agent 200-3, which has received the management item detection packet from the agent 200-1, reads AAA item information from the managed resource managed and attaches it to the management item detection packet. In step S600, the method checks whether the neighboring agent exists in step S700.

The agent 200-4 checks that no adjacent agent exists in the routing table, and transmits a management item detection result packet to the control manager 100 (S800).

The control management unit 100 receives the management item detection result packet and reads the information of the management item AAA of all the managed target resources stored in the packet and stores the information in the DB for the target or applies the threshold value of the corresponding information. The operation such as determining whether or not to proceed (S900).

As such, the control management unit 100 instructs the first agent 200-1 to detect the management information data required and then performs other tasks in parallel until receiving the result data from the final agent 200-4. Since it can reduce the computational burden of the control management unit, it is possible to prevent work delay due to the computational burden.

Next, the routing table stored in the configuration management DB of the control management unit and the agent used in the management method of the communication system of FIG. 7 will be described in more detail with reference to FIGS. 8 to 11.

8 is a configuration management information stored in the agent configuration management DB (240) managed by each agent 200, one of the agent routing table required to propagate a command transmitted from the control management unit 100 to a neighboring agent Is a diagram showing an example.

As shown in FIG. 8, the IP address of the neighboring agent and the port number of the neighboring agent are recorded in the routing table. The IP address and port number of the neighbor agent are necessary when transmitting a command of the control management unit 100 or receiving the state information of the neighbor management resource.

When a failure occurs in a managed resource managed by the neighbor agent 200-2, the agent 200-1 receives failure information. The agent 200-1 receiving the failure information, the agent routing stored in the agent configuration management DB 240 using the address of the next agent 300-3 to which the agent 200-2 delivers the message as the current agent. Update the table.

For example, an agent with an ID of 001 receives a status confirmation command from the control management unit, and transfers the status confirmation command to an agent with an ID of 002 again. In case of failure of managed resource managed by agent of 002 ID, the control management unit routes the ID of 002 agent to neighbor agent of routing table stored in the agent configuration management DB according to the situation. The 003, the ID of the adjacent agent stored in the table, is transmitted and updated to prevent the command delivery system from being interrupted by the agent with the failed 002 ID.

9 is a diagram illustrating an example of information stored in the configuration management DB 140 managed by the control manager 100.

The configuration management DB 140 managed by the control management unit 100 through the DB management unit 130 stores and manages information related to an IP address of an agent and a managed resource installed in a managed resource managed by the control management unit. do.

Using the table, the control management unit sends a command regarding the status information of the agent whose sequential path ID is set to '0', and if there is a normal response from the agent, a command related to checking the status information to the agent adjacent to the agent again. Send a message to execute the command so that the command can be executed for all agents in the path.

10 is a diagram illustrating a management item table and a management item table for each resource to be managed.

The management item table and the management item table for each managed resource separately define the managed items necessary to detect failure conditions or performance information of the managed resource for each managed resource. This table is used to manage the measurements for each of the separate management items.

That is, the management item table defines management items that can measure the failures or performance values of the managed resources to be managed by the corresponding management system, and the management item table for each managed resource is any item among the items defined in the management item table. Table for storing information about whether the management target resource is set as a management item.

Using these two tables, the control management unit collects measurement items for each management item for abnormality of a specific management item or determines abnormality for the managed resources managed by the control table.

 That is, in order to determine whether there is a measurement value or abnormality about a specific management item for the managed resources managed by the control manager periodically or as needed, a specific management target resource is used by using a routing table grouping the managed resources into groups. It sends the command to the next agent set in the routing table to the agent installed in the system to detect the information of a specific management item for all managed resources or to determine whether there is an error.

11 is a diagram illustrating a management item detection packet to which a result of management items of an agent is attached.

It is a management item detection packet used to store the results of the extraction of selective item information and the determination of abnormality of each item to be managed by each managed resource and deliver the result to the control management unit.

The management item detection packet is used for a different purpose than the agent configuration management DB (240). Specifically, the control manager transmits a management item detection packet to the first agent defined in the routing table among the management items managed by the control manager, and the first agent manages the information that the control manager has about the management item requested by the control manager. After attaching to the detection packet, it is delivered to the adjacent agent defined in the agent configuration management table managed by itself.

That is, the agents installed in the managed resource constituting the communication network take over the management item detection packet, add the information of the corresponding management item of the managed resource managed by the agent to the packet, and manage the agent configuration management again. The address of the neighbor agent stored in the DB is referred to and passed to the neighbor agent.

In order to collect management item information, the final agent on the routing path adds its own management item information to the packet and sends the packet to the receiving port of the predefined control management unit. This is a method of extracting management item information.

This method is a concept of a different concept from the method of moving an agent and inserting executable code into the agent and executing another code whenever necessary. This has the advantage of reducing the computational burden of.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and various other changes and modifications are possible.

According to the present invention, in the operation of the management system composed of the control management unit and the agent, it is possible to reduce the excessive computational load unilaterally on the control management unit or the agent. Therefore, malfunctions such as failure to detect or delay even when a failure occurs due to excessive computational load or failure to collect all management information data related to the status of all managed resources within a proper time can be greatly reduced.

In addition, by using the management item detection packet delivered by the control management unit, the state of all managed resources is attached to one packet and finally transmitted to the control management unit. By doing so, it is possible to significantly reduce the computational burden of the control management unit, as compared to the method in which the control management unit individually issues status report commands to all managed resources and receives and processes the status information.

In terms of agents, the computational burden is much less than storing complex operations and preconditions and voluntarily reporting abnormalities of the managed resources to the control department. In addition to this, there is an advantage in that not only the control management unit monitors one agent but also, in some cases, the neighbor agent can also be monitored in a plurality of forms.
