Description

  The present invention relates to an intermittent connection environment notification system, an intermittent connection environment notification method, a connection source, and the like, in which a management target machine intermittently connects to a management server. The present invention relates to an information processing apparatus and a connection source information processing apparatus program.

Conventionally, a business entity such as a company generally manages hardware such as an information processing apparatus such as a personal computer or a server, or software assets installed in the information processing apparatus.
In order to perform such asset management, hardware information, installed software information, and the like are collected by introducing dedicated software into the information processing apparatus and executing it at a predetermined timing. These pieces of information are transmitted to the management server, and the asset information of the information processing apparatus to be managed (hereinafter sometimes referred to as a management target machine) is integratedly managed by the management server.

In addition, the management server is expected to monitor the managed machine based on the collected asset information and appropriately notify the detected abnormality to the user of the detection source asset when an abnormality is detected.
For example, the license of the installed software, disk usage, installation time, etc. are monitored by the management server, and if an abnormality such as license expiration or disk capacity shortage is detected, this is used for the detection source asset. Need to be notified.

Thus, in order to realize notification from the management server to the managed machine, it is necessary to establish a network connection between these information processing apparatuses.
However, there is a large-scale asset management in a company, such as managing tens of thousands of information processing apparatuses with a single management server.
In such large-scale asset management, it is difficult to always establish a network connection between the management server and the managed machine, and an intermittent connection is usually performed.

Many companies have a firewall for each management department. If the management server and the managed machine belong to different network segments, establish a network connection from the management server to the managed machine. Sometimes it is impossible.
Therefore, in such a case, in order to establish a network connection between the management server and the managed machine, it is necessary to perform a network connection from the managed machine side toward the management server.

  However, in the method of network connection from the managed machine side to the management server, when the management server sends notifications to multiple managed machines, it is necessary to wait for connections from all the managed machines that are the notification destinations. is there. For this reason, only the connection from some managed machines is not established, the notification by the management server is not executed, and the processing time of the entire notification process may be delayed.

Here, when intermittent connection is made between multiple managed machines and the management server, a technology related to a method for notifying messages, etc. from the management server to multiple managed machines in a short time For example, an e-mail service providing system described in Patent Document 1 can be cited.

This message information may include a network ID, a machine ID, and a message ID.

The message transmission unit 113 transmits the message information acquired by the message acquisition unit 112 to the connection source management target machine 130.
When the machine ID in the message information matches the machine ID of the connection source management target machine 130, the message deletion unit 114 deletes the record corresponding to the message information from the message list 122 and updates the message list 122. .
Further, when the message deletion unit 114 receives the reception completion notification from the notification destination management target machine 140, the message deletion unit 114 deletes the record of the management target machine corresponding to the reception completion notification from the message list 122 and updates the message list 122. To do.

  Note that the configuration for performing asset management by the management server 110 is not particularly limited, and any conventionally known configuration can be used, and thus the description of the configuration is omitted.

The managed machine information database 120 is a storage unit that stores a managed machine ID management table 121 and a message list 122.
As shown in FIG. 3, the management target machine ID management table 121 stores correspondence information between the machine ID of the information processing apparatus managed by the management server 110 and the network ID of the network segment to which the information processing apparatus belongs. ing.

  As shown in FIG. 3, the message list 122 stores a network ID, a machine ID, and a message ID in association with each other. The main body of the message is stored in a predetermined storage means in association with the message ID, and is acquired and output using the message ID. The specific processing contents performed using the main body of the message may be arbitrary as to which storage means the main body of the message is stored and at which timing.

The managed machine is an information processing apparatus such as a personal computer or a server that is managed by the management server 110.
In FIG. 1, a connection source managed machine 130 indicates a machine connected to the management server 110 among managed machines.
The notification destination managed machine 140 is a machine other than the connection source managed machine 130 among the managed machines. In the case of simply a managed machine, both of them are shown.

  As shown in FIG. 4, the managed machine includes an ID storage unit 131 (141), a server access unit 132 (142), a message reception unit 133 (143), a communication destination determination unit 134 (144), and a message processing unit 135 ( 145), a message transmission unit 136 (146), and a reception completion notification unit 137 (147).

  Among these configurations, the ID storage unit 131, the server access unit 132, the message reception unit 133, the communication destination determination unit 134, the message processing unit 135, and the message transmission unit 136 are mainly configured so that the managed machine is the connection source managed machine 130. The message reception unit 143, the message processing unit 145, and the reception completion notification unit 147 function mainly when the managed machine becomes the notification destination managed machine 140. Hereinafter, these configurations will be described.

First, each of the above components in the connection source management target machine 130 will be described.
The ID storage unit 131 is a storage unit that stores information related to the managed machine, and includes the ID of the network to which the managed machine numbered by the ID numbering device 150 belongs, the ID of the managed machine, and the management Stores the address of the target machine.

The network ID is identification information for uniquely identifying the managed machine side network segment 180.
The machine ID is identification information for uniquely identifying all managed machines in the managed machine side network segment 180, and the address is information indicating a connection destination to the managed machine corresponding to the machine ID.

The server access unit 132 connects to the management server 110 and transmits to the management server 110 the network ID of the network segment to which the connection source managed machine 130 belongs and the machine ID of the connection source managed machine 130.
The message receiving unit 133 receives message information including a network ID, a machine ID, and a message ID from the management server 110.
The communication destination determination unit 134 compares the machine ID received by the message reception unit 133 with the machine ID of the connection source managed machine 130 itself, and determines whether or not they match.

  If the received machine ID matches its own machine ID as a result of the determination by the communication destination determination unit 134, the message processing unit 135 executes a corresponding predetermined message processing based on the message information from the management server 110. . In this message processing, for example, a message body is acquired from a predetermined storage unit based on the received message ID, and is output to a display unit or the like in the managed machine so that the user of the managed machine can view it. Can be performed.

  If the received machine ID does not match its own machine ID as a result of the determination by the communication destination determination unit 134, the message transmission unit 136 sends the management server 110 to the other notification target managed machine 140 corresponding to the machine ID. Send message information from.

Next, each configuration of the notification destination management target machine 140 will be described.
The message reception unit 144 receives the message information transmitted from the message transmission unit 113 in the connection source management target machine 130.
The message processing unit 145 executes message processing based on the message information received from the connection source management target machine 130. As in the case of the connection source managed machine 130, the specific processing content itself of the message processing is not particularly limited, and can be, for example, a message display processing.

The reception completion notification unit 147 appropriately receives message information from the management server 110 after the notification destination managed machine 140 receives message information from the connection source managed machine 130 or executes message processing. A reception completion notification indicating that it has been completed (or has been executed) is transmitted. This reception completion notification includes a network ID and a machine ID.
When the message deletion unit 114 of the management server 110 receives the reception completion notification from the notification destination management target machine 140, the message deletion unit 114 deletes the record of the management target machine corresponding to the reception completion notification from the message list 122, and the message list 122 is updated.

  The ID number assigning device 150 is arranged for each management target side network segment 180, assigns a network ID for uniquely identifying the segment, and uniquely assigns all managed machines belonging to the segment. Numbering machine ID for identification. Note that the network ID and machine ID need not be limited to numerical values, and may include characters, symbols, and the like. For example, the network ID can be generated as a unique value for each network segment using a network domain name or the like.

  When there is an ID numbering request from the connection source management target machine 130, the ID numbering device 150 executes ID numbering processing. Then, the connection source management target machine 130 stores, in the ID storage unit 131, the network ID and machine ID numbered by the ID numbering device 150, and ID address information including an address corresponding to the machine ID.

It should be noted that all managed machines are similarly assigned numbers by the ID numbering device 150 so that any managed machine in the managed network segment 180 can be the connection source managed machine 130. The ID address information can be stored in the ID storage unit in each managed machine.
In addition, by transmitting the ID address information stored in the ID storage unit 131 of the connection source managed machine 130 from the connection source managed machine 130 to another managed machine, the ID address information is previously stored in the ID of each managed machine. You may memorize | store in a memory | storage part.

  Next, a processing procedure in the intermittent connection environment notification system of this embodiment will be described with reference to FIGS. FIG. 5 is an operation procedure diagram showing a processing procedure from network ID acquisition to message delivery in the intermittent connection environment notification system of this embodiment. FIG. 6 is an operation procedure diagram showing a processing procedure from message delivery to processing completion in the system.

  First, a network ID and a machine ID are assigned to each managed machine in advance (steps 10 and 11). At this time, the ID numbering apparatus 150, based on the numbering request from the connection source managed machine 130, the network ID of the management target side network segment 180 to which the connection source managed machine 130 belongs and the management target side network segment 180. The machine IDs of the managed machines (connection source managed machine 130 and notification destination managed machine 140 in the example of FIG. 1) are numbered, and these pieces of information are transmitted to the connection source managed machine 130.

  The connection source management target machine 130 stores the network ID and machine ID numbered by the ID numbering device 150 and ID address information including an address corresponding to the machine ID. Although not used in this embodiment, the ID address information is actually assigned to another managed machine (notification destination managed object) so that any managed machine in the managed network segment 180 can be the connection source managed machine 130. Machine 140) also holds it.

Next, the connection source managed machine 130 connects to the management server 110 (step 12), and transmits the network ID and machine ID allocated by the connection source managed machine 130 to the management server 110.
When the management server 110 acquires the network ID from the connection source managed machine 130 (step 13), the management server 110 searches the managed machine information database 120 using this network ID, and message information addressed to the managed machine with the same network ID. If it exists, it is acquired (step 14). This message information includes a network ID, a machine ID, and a message ID.

Next, when there is message information addressed to a managed machine having the same network ID (YES in step 15), the management server 110 transmits the message information to the connection source managed machine 130 (step 16).
When the message information includes a message addressed to the connection source managed machine 130, that is, when data including the machine ID of the connection source managed machine 130 exists (YES in step 17), The management server 110 deletes the record corresponding to the machine ID from the message list 122 (step 18). In the message list 122, the “notified” flag may be recorded in the record and handled as deleted.

Next, as illustrated in FIG. 6, the connection source management target machine 130 executes the following processing for each record in the received message information.
First, the machine ID is acquired from the message information (step 30), and it is determined whether the notification destination of the message information is the connection source managed machine 130 itself or another managed machine (step 31). ).
If the machine ID (notification destination machine ID) acquired from the message information matches the machine ID of the connection source managed machine 130 itself, the connection source managed machine 130 sets the message ID included in the message information. Corresponding predetermined processing is executed (step 32).

On the other hand, when the machine ID acquired from the message information does not match the machine ID of the connection source managed machine 130 itself, the connection source managed machine 130 sets the address of the notification destination managed machine 140 corresponding to the machine ID. Obtained from the ID storage unit 131.
Then, the message information corresponding to the machine ID is transmitted to the notification destination management target machine 140 of the acquired address and delivered (step 33).

If the connection source managed machine 130 fails to deliver the message information to the notification destination managed machine 140 (NO in step 34), the connection source managed machine 130 fails to deliver to the notification destination managed machine 140 to the management server 110. A notification indicating this is transmitted (step 35).
On the other hand, when the message information has been successfully delivered (YES in step 34), in the notification destination managed machine 140, as in the case of the connection source managed machine 130, a predetermined ID corresponding to the message ID included in the message information is set. Is executed (step 36).

The notification destination managed machine 140 has received the message information from the management server 110 after receiving the message information from the connection source managed machine 130 or executing a predetermined process corresponding to the message ID. Is transmitted (step 37).
When receiving the reception completion notification from the notification destination managed machine 140, the management server 110 deletes the record corresponding to this reception completion notification from the message list 122 and updates the message list 122 (step 38).

  As described above, according to the notification system in the intermittent connection environment of this embodiment, the management server conventionally connects from the notification-destination managed machine using the opportunity that the connection-source managed machine connects to the management server. The message addressed to the notification-destination managed machine that has been sent after waiting can be sent to the connection-source managed machine, and can be sent to the notification-destination managed machine on behalf of the connection-source managed machine.

According to the conventional notification method under intermittent connection environment, for example, when notification from the management server to two managed machines, the connection from both of the two managed machines had to be individually queued .
For this reason, the time from when a message needs to be sent on the management server until the message is sent to all managed machines is connected to the management server later. The time until connection by the managed machine was almost the same.

  On the other hand, if the notification system in the intermittent connection environment of this embodiment is used, the time from when the message needs to be transmitted on the management server until the message is transmitted to all managed machines. Of the two managed machines almost coincides with the connection time by the managed machine connected to the management server first.

  As described above, according to the notification system in the intermittent connection environment of this embodiment, the message transmission time from the management server to all the managed machines is until one of the managed machines first connects to the management server. As the number of managed machines increases, the relative transmission time is greatly shortened.

If the result of determination by the communication destination determination unit 294 indicates a match, the message processing unit 295 executes a predetermined process corresponding to the message ID in the message information transmitted from the management server 210.
If the result of determination by the communication destination determination unit 294 indicates that they do not match, the message transmission unit 296 uses the network ID and machine ID transmitted from the management server 210 as the virtual network ID and virtual machine ID, respectively, as a virtual managed machine ID. The management table 301 is searched, and the actual network ID (actual network ID) and actual machine ID (actual machine ID) of the corresponding managed machine are acquired.

Then, the message information is transmitted to the managed machine corresponding to the acquired real network ID and real machine ID.
Note that the address of the managed machine corresponding to the real network ID and the real machine ID may be held in the virtual managed machine ID management table 301 or in the sub management server 290, and this is used for sub management. Connection from the server 290 to the managed machine can be performed.

  The ID numbering unit 297 manages each machine belonging to the sub management server side network segment 310, the connection source managed machine side network segment 281 or the communication source managed machine side network segment 282, which is the management target of the management server 210. Each real network ID and real machine ID, and virtual network ID and virtual machine ID are allocated in advance.

These pieces of association information are stored in the virtual management target machine ID management table 301 in the virtual management target machine information database 300.
FIG. 10 shows the data structure of the virtual management target machine ID management table 301 created in this way.

  In the example of FIG. 10, “1” as the real network ID, “1” as the real machine ID, “S” as the virtual network ID, and “10” as the virtual machine ID of the connection source managed machine 230 illustrated in FIG. “2” as the real network ID of the target managed machine 240, “1” as the real machine ID, “S” as the virtual network ID, “20” as the virtual machine ID, and “S” as the real network ID of the sub-management server 290 The real machine ID is “1”, the virtual network ID is “S”, and the virtual machine ID is “100”.

In this embodiment, the same virtual network ID as the network ID of the sub management server 290 is allocated, but a different ID may be used.
Further, the ID numbering unit 297 stores the virtual network ID and virtual machine ID of the sub management server 290 in the ID storage unit 291.

In addition, the managed machine information database 220 stores a virtual network ID and a virtual machine ID assigned by the sub management server 290 instead of the real network ID and the real machine ID.
As shown in FIG. 11, the virtual network ID and the virtual machine ID are also stored in the network ID and the machine ID of the message list 222, respectively, and the message ID is stored in association with these.

  Next, a processing procedure in the intermittent connection environment notification system of this embodiment will be described with reference to FIGS. FIG. 12 is an operation procedure diagram showing a processing procedure from network ID acquisition to message delivery in the intermittent connection environment notification system of this embodiment. FIG. 13 is an operation procedure diagram showing a processing procedure from message delivery to processing completion in the system. Note that real network ID, real machine ID, virtual network ID, and virtual machine ID assignment processing are omitted.

First, when the connection source managed machine 230 is connected to the sub management server 290 (step 50), the sub management server 290 is connected to the management server 210 (step 51), and the connection source managed machine 230 and the sub management server 290 are connected. The virtual network ID allocated to the one virtual network to which and the like belong and the virtual machine ID of the sub management server 290 are transmitted.
In this embodiment, “S” and “100” are allocated as the virtual network ID and the virtual machine ID of the sub management server 290, respectively.

When the management server 210 acquires the virtual network ID from the sub management server 290 (step 52), the management server 210 searches the message list 222 based on the virtual network ID and acquires corresponding message information (step 53).
In this embodiment, when the virtual network ID acquired by the management server 210 is “S” and a record as shown in FIG. 11 is stored in the message list 222, the management server 210 determines that the virtual managed machine information Three pieces of message information corresponding to the network ID “S” are acquired from the database 300.

Next, since the message information exists as a result of the search in Step 53 (YES in Step 54), the management server 210 transmits these to the sub management server 290 and delivers them (Step 55).
In addition, the management server 210 compares the machine ID in the message information with the virtual machine ID acquired from the sub management server 290, and deletes the matching record from the message list 222 because the notification has been completed. (Steps 56, 57).
In the present embodiment, since the virtual machine ID of the sub management server 290 is “100”, the network ID “S”, the machine ID “100”, and the message ID “M2” in the message information shown in FIG. Is deleted.

Next, the sub management server 290 acquires a machine ID from the received message information (step 70), and determines whether or not it matches the virtual machine ID of the sub management server 290 (step 71).
If they match (YES in step 71), the corresponding predetermined message processing is executed based on the message ID in the corresponding message information (step 72).

On the other hand, if they do not match (NO in step 71), the sub-management server 290 searches the virtual managed machine information database 300 using the machine ID of the received message information as a virtual machine ID, and from the virtual managed machine ID management table 301 The corresponding real network ID and real machine ID are acquired (step 73).
Then, the message information is transmitted and delivered to the managed machine corresponding to the acquired real network ID and real machine ID (step 74).
When the delivery has failed (NO in step 75), the sub management server 290 transmits a notification indicating that the delivery has failed to the management server 210 (step 76).

If the message information has been successfully delivered (YES in step 75), the managed machine that has received the message information executes a predetermined message process corresponding to the message ID in the message information (step 77).
Then, a reception completion notification including message information is transmitted to the management server 210 via the sub-management server 290 (step 78), and the management server 210 executes these based on the network ID and machine ID included in the reception completion notification. Is deleted from the message list 222 (step 79).

As described above, according to the intermittent connection environment notification system of this embodiment, when managing managed machines belonging to a plurality of network segments, the IDs of managed machines belonging to these network segments are set to the same ID. It can be virtualized to belong to a network segment.
Thereby, message information can be transmitted to the managed machines belonging to all the segments by the sub-management server when the machine in one segment is connected to the management server.

It goes without saying that the present invention is not limited to the above embodiment, and that various modifications can be made within the scope of the present invention.
