Large-scale network remote management method and recording medium recording large-scale network remote management program

Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention relates to a large-scale network remote management method in which a manager collects management information managed by a plurality of agents from each agent and manages them collectively, and in particular, a large-scale method capable of reducing management packets between the manager and each agent. Related to network remote management methods and recording media on which large-scale network remote management programs are recorded.

【0002】

[Conventional technology]

FIG. 5 is a diagram showing an example of a network management method using SNMP (Simple Network Management Protocol), which is widely used as a network management protocol for the Internet. The communication network management system by SNMP is composed of an SNMP manager 51 that manages the network and an agent 53 that is a target device to be managed. Agent 53 stores a collection of data elements called management information base (MIB) 55, such as hardware switch settings and variable values stored in memory, as management information. The manager 51 issues a request to the agent 53 and manages it by referring to or rewriting these MIB data.

【0003】

However, as the scale of the network to be managed increases, the number of these management packets increases as the number of devices to be managed increases, and the load on the manager who manages the network also increases, which is a problem.

【0004】

As a method of solving this problem, as shown in FIG. 6, for example, a sub-manager 59 is installed between the manager 51 and the agent group 57 including the agent 53, and the sub-manager 59 manages the management information of the subordinate agent group 57. In summary, by relaying the communication between the manager 51 and the agent group 57, a method of distributing the traffic to the manager 51 and the load of the manager 51 can be considered.

【0005】

[Problems to be Solved by the Invention]

In the conventional method described above, the above problems can be solved by installing the sub-manager 59, but as the network becomes larger, the number of sub-managers 59 increases, and the manager 51 and the sub-managers increase. The number of management packets when exchanging management information between 59 increases, and the load on the manager 51 also increases. In order to further distribute, it is necessary to deepen the hierarchy, but if a failure occurs in the upper sub-manager 59 that relays, the influence on the subordinates will be widespread, so the higher the hierarchy, the higher. The problem remains that reliability is required.

【0006】

The present invention has been made in view of the above, and an object of the present invention is to suppress an increase in traffic due to an increase in the number of managed devices, reduce the load on the manager, and even if the network is expanded, the conventional invention is used. It is an object of the present invention to provide a recording medium in which a large-scale network remote management method and a large-scale network remote management program that can maintain the same degree of reliability are recorded.

【0007】

[Means for solving problems]

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a system configuration for implementing a large-scale network remote management method according to an embodiment of the present invention. In the figure, the manager 51 that manages and controls the management information of each agent by using the configuration and network management program of a plurality of agent groups 57a to 57n that manage the management information including the configuration information and the status information for each resource unit of the network. The configuration of is the same as the conventional one, but it is provided corresponding to each of the agent groups 57a to 57n, and relays the communication between each agent group 57 under the correspondingly provided and the manager 51. The plurality of sub-managers 11a to 11n transfer the management information acquired by each sub-manager 11 from the agent group 57 under it as shown by arrows 21 and 23 between the sub-managers by a predetermined transfer route between the sub-managers. It is very different from the conventional one in that it is configured to obtain. In this embodiment, the predetermined transfer route is set as sub-manager 11a sub-manager 11b sub-manager 11c ... sub-manager 11n, and sub-manager 11a is the first sub-manager and the sub-manager. 11n is the last submanager. Further, in FIG. 1, the arrow 21 indicates a transfer request from the upper sub-manager 11 to the next sub-manager 11 in the transfer route, and the arrow 23 indicates the response from the lower sub-manager 11 to the upper sub-manager 11. There is.

【0024】

Each sub-manager 11 configured in this way receives the management information managed by the agent group 57 under its own control, transfers this management information to the next sub-manager 11 in the transfer route, and also transfers the management information to the next sub-manager 11 in the transfer route. The sub-manager 11 that receives the management information transferred from is added the management information managed by the agent group 57 under its own control, and is transferred to the next sub-manager 11. That is, the sub-manager 11b that receives the management information from the sub-manager 11a adds the management information of the agent group 57b under its own control to the received management information, transfers it to the next sub-manager 11c, and transfers it to the sub-manager 11c. Adds the management information of the agent group 57c under its own to the management information received from the sub-manager 11b, and transfers it to the next sub-manager 11d. Similarly, each sub-manager 11 on the transfer route adds the management information of the agent group 57 under its own control to the management information transferred, and transfers the information to the next agent group 57. .. Then, the sub-manager 11n received at the end adds the management information of the agent group 57 under its own control to the received management information, and then collectively notifies the manager 51 of the management information.

【0025】

Next, the operations of the manager 51 and the sub-manager 11 will be described with reference to the flowcharts shown in FIGS. 2 to 4.

【0026】

First, the operation of the manager 51 will be described with reference to the flowchart shown in FIG. In FIG. 2, when the periodic collection cycle of management information is reached (step S11), the manager 51 is on the transfer route based on a predetermined transfer route configured among a plurality of sub-managers 11 to transfer the management information. Make a periodic collection request for management information with the first sub-manager 11a as the representative sub-manager (step S13). Then, it monitors whether or not there is a response from the first sub-manager 11a (step S15), and if there is a response, the manager 51 returns to step S11 and waits until the next periodic collection cycle, but if there is no response, , The next sub-manager 11 on the transfer route is set as the first sub-manager (step S17), and the process returns to step S13 to make a periodic collection request for management information to this sub-manager. If there is a response from the next submanager, it waits until the next periodic collection cycle. If there is no response from the next sub-manager, the operation of making a periodic collection request for management information is repeated with the next sub-manager on the transfer route as the first sub-manager.

【0027】

Next, the operation of the sub-manager 11 when there is a periodic collection request for management information from the manager 51 will be described with reference to the flowchart shown in FIG. When the sub-manager 11 receives the periodic collection request for management information from the manager 51 (step S21), the sub-manager 11 returns a response to the manager 51 (step S23). The sub-manager 11 then checks for the next sub-manager 11 on the forwarding route (step S25). If there is a next sub-manager 11, it checks if the next sub-manager 11 responds (step S27), and when the next sub-manager 11 responds, the sub-manager 11 is a group of agents under its own control. Transfer the management information of 57 to the next sub-manager 11 (step S29), and then return to the first step.

【0028】

Also, in the check for whether or not there is the next sub-manager 11 in step S25, if there is no next sub-manager 11, the manager 51 is notified of the management information of the agent under its own control (step S31). , Go back to the first step.

【0029】

Next, the operation of the sub-manager 11 when management information is received from another sub-manager 11 on the transfer route will be described with reference to the flowchart shown in FIG.

【0030】

When each sub-manager 11 receives the management information transferred from the other sub-managers 11 located higher on the transfer route (step S41), each sub-manager 11 responds to the transfer source which is the other sub-manager 11 located higher. Return (step S43) and then check for the next submanager 11 on the forwarding route (step S45). If there is a sub-manager 11 under this level, check whether the next sub-manager 11 responded (step S47), and if there is no response, return to step S45 and repeat the same operation to respond. Until then, it skips to the next sub-manager 11 on the transfer route, and when there is a response, it adds the management information of the agent group 57 under its own control and transfers it to the next sub-manager 11 (step S49). Then go back to the first step and repeat the same operation.

【0031】

Also, in the check in step S45, if there is no next sub-manager 11, that is, if there is no subsequent sub-manager 11, the management information of the agent group 57 under its own is added. , Notify manager 51 of management information (step S51).

【0032】

As described above, in the present embodiment, the manager 51 makes a periodic collection request for management information to the head manager 11a of the transfer route, and the head sub-manager 11a transfers the management information of the subordinate agent group 57 in response to the request. Transfer to the next sub-manager 11b of the root, each sub-manager 11 adds the management information of the subordinate agent group 57 to the management information from the previous sub-manager 11, transfers to the next sub-manager 11, and finally The sub-manager 11 adds the management information of the subordinate agent group 57 to the management information transferred from the previous sub-manager 11, and then collectively notifies the manager 51 of the management information.

【0033】

If the first submanager 11a does not respond to the periodic collection request from the manager 51, the lower submanager of the first submanager, specifically the lower submanager, which can respond to the forwarding route, is the highest submanager that can respond. In response to the periodic collection request, the management information of the agents 57 under its own control is transferred to the next sub-manager of its own according to the transfer route. Further, each sub-manager 11 changes the transfer destination to the next sub-manager of the transfer-destination sub-manager according to the transfer route when the transfer-destination sub-manager 11 does not respond. Furthermore, if all of the transfer destination sub-managers 11 do not respond, each sub-manager 11 is set to notify the manager 51 of the management information collectively as the last sub-manager 11 on the transfer route. ..

【0034】

[Effect of the invention]

As described above, according to the present invention, the manager makes a periodic collection request for management information to the head manager of the transfer route, and the head sub-manager receives the management information of the subordinate agent next to the transfer route in response to the request. Transfer to the sub-manager of, each sub-manager adds the management information of the subordinate agent to the management information from the previous sub-manager, transfers to the next sub-manager, and the last sub-manager transfers from the previous sub-manager After adding the management information of the subordinate agent to the management information that is received, the management information is collectively notified to the manager, so even if the network expands further and the number of sub-managers increases, the management packets to the manager will increase. It is possible to suppress the increase in traffic and the increase in the load on the manager.

【0035】

Further, according to the present invention, when the first sub-manager does not respond to the periodic collection request, the sub-managers below the first sub-manager respond to the periodic collection request in the transfer route, so that the first sub-manager cannot respond for some reason. However, the sub-managers in the lower level can respond and respond appropriately to the periodic collection request from the manager, and it is also possible to identify the sub-manager who does not respond for some reason. Also, even if the sub-manager is abnormal, only the subordinate agents are affected.

【0036】

Further, according to the present invention, if the transfer destination sub-manager does not respond, the sub-manager changes the transfer destination to the next sub-manager, so that the transfer process of management information is suitable even if the sub-manager cannot respond for some reason. It can be done reliably, and it is also possible to identify sub-managers who cannot respond for some reason. Also, even if the sub-manager is abnormal, only the subordinate agents are affected.

【0037】

According to the present invention, when all of the transfer destination sub-managers do not respond, the sub-manager notifies the manager of the management information collectively as the last sub-manager, so that all the sub-managers after the transfer destination are abnormal. Even in that case, the management information up to that point can be collectively notified to the manager.
