Description

  The present invention relates to a network connection setting system for setting a network, a connection device used for setting a network, a network setting method, and a network setting program.

  When a network is newly constructed by introducing a network device such as a switch, there is a strong demand for cost reduction for maintenance operation of these network devices. Therefore, an operation method of remotely controlling each network device using a management server is generalized as a first related technique related to the present invention (see, for example, Patent Document 1).

  However, in order to remotely control and operate network devices that make up a network using a management server, it is necessary to connect information processing terminals such as personal computers locally to all network devices and make necessary settings. There is. In order to control these network devices from a remote location, there is a problem that a large burden is imposed on this setting work when the network devices are first introduced.

  That is, when the management server first accesses the network device, each address information is set in advance for the network device to be accessed, and the information is accurately registered in the management server. Alternatively, it is necessary to search for these network devices from the management server. Therefore, there is a problem that it takes time to input address information, and it takes time to search for a network device. Further, if there is an error in the input or setting of address information, the corresponding network device cannot be accessed.

  Therefore, it has been studied to simplify the network device setting work. As one of them, it has been proposed to mount an external memory in a network device. In this proposal, an exchangeable external memory that stores setting information in advance is prepared, and a network device is set using the external memory.

  However, as network devices increase in the number of products that can be set on a web basis, the cost reduction is progressing. For this reason, the use of an external memory storing information for setting the network causes an increase in the cost of the network device, and is difficult to apply to an inexpensive network device with severe price competition. Such relatively inexpensive network devices are in a situation where it is difficult to provide redundant functions and mechanisms.

  Therefore, a network setting device storing network setting information is prepared, and this is connected to a network connection device to be set using a USB (Universal Serial Bus) cable to set the network setting information. It has been proposed as a second related technique (see, for example, Patent Document 2). In the second related technology, when a predetermined trigger such as connecting the network setting device to the network connection device with a USB cable is detected, setting information is transmitted from the network setting device to the network connection device. As a result, setting information is set in the network connection device, and connection to a desired network becomes possible. In addition to detecting the connection of the USB cable, the trigger can be generated by an act of pressing a predetermined button, for example.

  According to the second related technique, after sending the setting information to the network connection device, the network setting device can be reused for another network connection device by removing the USB cable. Therefore, the cost increase of the network connection setting system itself for setting for network connection is not particularly problematic.

JP 2007-140743 A (paragraphs 0047 to 0058, FIGS. 1 and 6) JP 2006-254077 A (paragraph 0029, paragraph 0030, FIG. 2)

  However, in the second related technique, there is a setting information storage unit that stores setting information in the network setting device. If the setting information stored in this setting information storage unit is information dedicated to a specific network connection device, the wrong setting will be made if the contractor connects the wrong network setting device to the network connection device. The connection may not succeed. At this time, there may be a case where the network connection device has a failure as a device, so the connection may not be successful. Occurs. In such a case, the cause of the failure is isolated and the setting work at the site is generated, which incurs labor costs and delays the time until network construction.

  In addition, when one network setting device collectively stores setting information for a plurality of network connection devices in the setting information storage unit, if the wrong selection button is pressed due to a mistake of the construction person, In the same manner as the above, there is a problem that incorrect setting information is set in the network connection device. Accordingly, if one network setting device is shared by a plurality of network connection devices, there is a high possibility that a construction error will occur.

  Further, when the second related technology is used, the setting information is stored in the setting information storage unit of the network setting device at least until the setting is completed. Therefore, for example, if the network setting device connected to the USB cable is lost or illegally acquired by a third party, the setting information may be read by others, which causes a security problem.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a network connection setting system, a connection device, a network setting method, and a network that are capable of setting a network connection that is secured when constructing a network using a network device and is unlikely to cause a cost increase To provide a setting program.

The second network device 102 ₂ is different from the specification of the apparatus, such as size, lamp display unit 137 and the plug-in port 138 on the front surface of the apparatus body 181 ₂ is disposed.

For example, the installer attaches one end of the connection cable 183 to one of the ports of the plug-in port unit 138 of the second network device 102 ₂ , and plugs the other end into the plug-in port unit of the first network device 102 _1. Attach to one of the 138 ports as shown by arrow 184. Assuming that both the first network device and the second network device of the present embodiment are router devices, the connection cable 183 uses a commercially available LAN (Local Area Network) cable. Therefore, the connection shown in FIG. 11 is the same as that conventionally performed.

The construction drawings adapted also to connect another network device 102 such as a network device 102 _M of the M to the first network apparatus 102 _1. For these connections, the same connection processing is performed using the connection cable 183.

FIG. 12 shows a state in which the first connection module is mounted on the first network device. Here, to avoid complicating the illustration, it is not shown connection cable 183 used for connection between the first network apparatus 102 ₁ and the other network devices 102 shown in FIG. 11.

First connection module 104 ₁ is of a quadrangular prism-like outer shape, and its distal end to one of the ports of the plug-in port 138, mounted is inserted as shown by arrow 191. The first connection module 104 keep the _first terminals of the male to the tip is provided, which may be fitted into the insertion opening of the port to configure port 138 for plugin. In the case where the first connection module 104 ₁ is provided with a male terminal at the tip, the size of the first connection module 104 ₁ itself or its tip may be larger than the port insertion port.

As described above, the contractor connects the _first to M-th network devices 102 _{1 to} 102 _M with the connection cable 183 (see FIG. 11) based on the construction drawings, and then continues to the first to M-th networks. A corresponding one of the first to _Mth connection modules 104 _{1 to} 104 M is attached to each of the devices 102 _{1 to} 102 _M.

Returning to the description of FIG. When the construction of the first to M-th network devices 102 _{1 to} 102 _M and the first to M-th connection modules 104 _{1 to} 104 _M is completed as described above, the construction worker connects the communication terminal 105 to the external network 106. To the management server 101 (step S206). When the first to M-th network devices 102 _{1 to} 102 _M are powered on, power is supplied to the _first to M-th connection modules 104 _{1 to} 104 _M , respectively. Accordingly, the communication terminal 105 can communicate with the first to Mth connection modules 104 _{1 to} 104 _M.

In this state, the first to Mth connection modules 104 _{1 to} 104 _M execute the “network device setting / connection test / device information reading process” described in detail below (step S207). When the above processing is completed, the first to Mth network devices 102 _{1 to} 102 _M start actual operation. The construction worker confirms the lighting state of the port state display lamp by the lamp display unit 137 (step S208), and ends a series of operations related to the network connection (end).

FIG. 13 shows a state of processing of the first connection module when executing the “network device setting / connection test / device information reading processing” described in step S207 of FIG. The second to M-th connection modules 104 _{2 to} 104 _M perform the same processing, but this is the same as the processing performed by the first connection module 104 ₁ , and thus illustration and description thereof are omitted. This will be described with reference to FIGS.

When the first connection module 104 ₁ is attached to the _first network device 102 ₁ (see FIG. 12), power is supplied from the power supply unit 139 to the internal power receiving unit 161. Thereby, the control unit 153 starts operation. Control unit 153 at this stage to check whether the first connection module 104 _first web communication section 155 is capable of connecting the communication terminal 105 (step S221). Construction's are on the power to the communication terminal 105, if the first connection module 104 ₁ becomes the state capable of connecting the communication terminal 105 (step S222: Y), the control unit 153 then the web The communication unit 155 checks whether the connection with the management server 101 is possible (step S223). Connecting web communication section 155 and the management server 101 is possible (step S224: Y), the first connection module 104 ₁ logs in the management server 101 (step S225).

At the time of login, the first connection module 104 ₁ reads an ID (identification) unique to the _first connection module 104 ₁ stored in the setting processing unit 156 and uses this as a management number. The management server 101 registers the management numbers of the _first to Mth connection modules 104 _{1 to} 104 _M as IDs of these modules in the setting information storage unit 117 in relation to the construction drawings. Therefore, the management server 101 can uniquely recognize the _first connection module 1041 used for the network connection work by referring to the ID used at the time of login and the planned construction date.

When the first connection module 104 ₁ logs in to the management server 101 in this manner, the first connection module 104 ₁ sends out an ARP (Address Resolution Protocol) packet to the first network device 102 ₁ to which the first connection module 104 ₁ is attached (step S226). Then, to obtain the corresponding information IP (Internet Protocol) address and MAC address (Media Access Control address) from the first connection module 104 ₁ (step S227). The acquired IP address is an address set for the _first network device 1021 at the time of factory shipment. Accordingly, the first connection module 104 ₁ logs in to the first network device 102 ₁ using the IP address set at the time of factory shipment and the acquired MAC address (step S228).

When the first connection module 104 ₁ completes the login to the _first network device 102 ₁ , this fact is notified to the management server 101 together with the MAC address of the first network device 102 ₁ (step S229). Thus, the management server 101 first connection module 104 ₁ of the connected network device with reference to first to each of the MAC address of the network apparatus 102 ₁ to 102 _M of the M stored in the setting information storage unit 117 Can be determined to be the first network device 102 ₁ .

Thereafter, the management server 101 sets the first network device 102 ₁ via the first connection module 104 ₁ and acquires device information of the _first network device 102 ₁ . After completing the setting of the _first network device 1021 as described above, the management server 101 controls the test processing unit 157 to perform a network connection test (step S230). Then, the result of the connection test is notified to the management server 101 (step S231), and the series of processing ends (end).

FIG. 14 shows a state of processing of the management server when this “network device setting / connection test / device information reading processing” is performed. The case where the first connection module 104 ₁ is attached to the _first network device 102 ₁ will be described as an example with reference to FIGS.

The management server 101 when the first connection module 104 ₁ is logged (step S251: Y), either from the ID (control number) of the first to M connection modules 104 ₁ -104 _M to determine logged (Step S252). Thereafter, when the first connection module 104 ₁ sends the MAC address of the first network device 102 ₁ to which it is connected, this is received (step S253: Y). The management server 101 reads setting information such as an IP address assigned in advance as corresponding to the received MAC address from the setting information storage unit 117. The management server 101 uses the web communication unit 115 to store the read setting information in the device information storage unit 136 of the first network device 102 ₁ via the first connection module 104 ₁ (step S254).

Thus, it is rewritten to the IP address where the first network device 102 ₁ of the apparatus information IP address of the factory which has been stored in the storage unit 136 is provided in the management server 101. This is to prevent the occurrence of such a situation because there is a risk of IP address contention among a plurality of network devices 102 if the network is configured using the factory-shipped IP addresses as they are. .

When the setting of the first network device 102 ₁ is completed as described above, the web communication unit 115 of the management server 101 passes through the first connection module 104 ₁ and the device information storage unit 136 of the first network device 102 _1. Is read out (step S255). Managing web communication section 115 of the server 101 controls the first connection module 104 _first test processor 157 using the device information, implementing the connection test of the network (step S256). When the result of the connection test is obtained, the web communication unit 115 of the management server 101 reads this result (step S257).

Management server 101 If the obtained result of the connection test for the first network device 102 _1, the first network apparatus 102 ₁ of the lamp display unit through the first connection module 104 ₁ using a web communication section 115 137 is controlled and the result of the connection test is displayed in a blinking state of the lamp (step S258). Thus the process of "Network device set-connection test, device information reading process" for the first network device 102 ₁ is completed.

The network connection setting system 100, the network device 102 ₁ to 102 _M of the first to M to be connected are present. Therefore, when the processing for the _first network device 102 ₁ is completed, the management server 101 returns to the processing of step S251 (return) and performs the same processing for the _{second to Mth} network devices 102 _{2 to} 102 _M. Will do. Of course, the processing of the management server 101 for the _first to M-th network devices 102 _{1 to} 102 _M may be performed in parallel in time.

According to this embodiment, as described above, the connection management server 101 by connecting the connection module 104 ₁ -104 _M first to M to the network device 102 ₁ to 102 _M of the first to M Since the setting is performed, the setting operation can be performed quickly and without an input error by a simple operation.

Further, since the first to Mth connection modules 104 _{1 to} 104 _M can be reused for the network device 102 to be newly connected, it is economical. Moreover, since the first to Mth connection modules 104 _{1 to} 104 _M are connected using the ports provided in the _first to Mth network devices 102 _{1 to} 102 _M , the first to Mth network devices 102 _{1 to} 102 _M need not be a special device.

  Further, according to the present embodiment, when the network device 102 is controlled remotely, the management server 101 accesses the connection module 104 and refers to the address information of the network device 102 stored therein. As a result, these network devices 102 can be reliably accessed without using special search means. In addition, manual input operations can be eliminated as much as possible in the setting operation for setting the network device 102 from a remote location, and troubles due to human error can be avoided.

According to the present embodiment, the first to M-th connection modules 104 _{1 to} 104 _M are detachable from the _first to M-th network devices 102 _{1 to} 102 _M. The possibility of obtaining cannot be denied. However, the first to M-th connection modules 104 _{1 to} 104 _M are collected by the builder after the network setting and the connection confirmation are completed. In addition, the first to Mth connection modules 104 _{1 to} 104 _M themselves do not need to hold information unique to the network device such as the MAC address in a state where the power is shut off. For this reason, the first to Mth connection modules 104 _{1 to} 104 _M are configured such that the built-in information is erased when the power supply is stopped after being removed from the _first to Mth network devices 102 _{1 to} 102 _M. It is also considered in terms of security.

It is also possible to connect the communication terminal 105 to only a part of the _first to M-th network devices 102 _{1 to} 102 _M by wire and connect the remaining network devices 102 wirelessly as described in the embodiment. It is.

  <Second Modification of Invention>

  FIG. 16 shows a network connection setting system in the second modification of the present invention. In FIG. 16, the same parts as those in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. In this network connection setting system 100B, as shown in FIG. 16A, the communication terminal 105 is connected to the management server 101 through the external network. This part is not different from the network connection setting system 100 of FIG.

On the other hand, FIG. 5B shows a logical topology of a network device to be connected as the local site network 400. The first network device 102 ₁ constituting the local site network 400 is connected to the internal network 103. The first network device 102 ₁ is connected to the second network device 102 ₂ by the communication cable 411 _12, the second network device 102 ₂ is connected to the third network device 102 ₃ by a communication cable 411 ₂₃ . The third network device 102 ₃ is connected to a fourth network device 102 ₄ by a communication cable 411 _34, the fourth network device 102 ₄ is connected to the network device 102 ₅ of the fifth through communication cable 411 _45. The third network device 102 ₃ is connected to the _sixth network device 102 ₆ by the communication cable 411 ₃₆ and is connected to the fifth network device 102 ₅ by the communication cable 411 ₃₅ . The fourth network device 102 ₄ is connected to a sixth network device 102 ₆ by a communication cable 411 ₄₆ is connected to the network device 102 ₇ of the seventh through communication cable 411 _47. Network device 102 ₇ 7 is connected to the network device 102 ₈ eighth by a communication cable 411 ₇₈ are connected by a communication cable 411 ₇₉ a ninth network device 102 _9. The ninth network device 102 ₉ is connected to the _first network device 102 ₁ by the communication cable 411 ₁₉ and is connected to the second network device 102 ₂ by the communication cable 411 ₂₉ .

Here, first to fourth, the seventh and ninth network apparatus 102 ₁ to 102 _4, 102 _7, 102 _9, first to fourth, seventh and ninth connection module 104 _{1-104 4} , 104 ₇ , and 104 ₉ are mounted in the same manner as in the previous embodiment. The first to fourth, seventh, and ninth connection modules 104 _{1 to} 104 ₄ , 104 ₇ , and 104 ₉ are connected to the communication terminal 105 by the radios 421 _{1 to} 421 ₄ , 421 ₇ , and 421 ₉ . It has become. In FIG. 16A and FIG. 11B, the asterisk (*) indicates the connection location of the radios 421 _{1 to} 421 ₄ , 421 ₇ , and 421 _{9 on} the drawing.

Fifth, the network device 102 ₅ sixth and eighth, 102 _6, 102 _8, these plug-ins for the port unit 138, respectively (see FIG. 8) connecting cable 431 _5, 431 _6, 431 ₈ end connection Has been. Among them, the other end of the fifth network device 102 ₅ plugins port portion 138 is connected at one end to the connection cable 431 _5, a fourth connection module 104 that is mounted to the fourth network device 102 _{4 4} is connected to the external port section 160 (see FIG. 9).

Similarly, the other end of the connection cable 431 ₆ having one end connected to the plug-in port portion 138 of the sixth network device 102 ₆ is connected to the third connection module 104 attached to the _third network device 102 _{3. 3} external port portions 160 are connected. The other end of the connection cable 431 ₈ connected at one end to the plug-in port portion 138 of the eighth network device 102 ₈ is the seventh connection module 104 ₇ attached to the _seventh network device 102 _7. The external port unit 160 is connected. Thus the fifth, the network device 102 _5, 102 _6, 102 ₈ sixth and eighth is not provided with an interface mechanism for connection module 104, the other network devices 102 present in a relatively short distance The connection module 104 is connected to the external port 160.

  In the network connection setting system 100B having such a configuration, redundant link connection is performed in order to increase the reliability of the network using a layer 2 switch (not shown). Therefore, if communication is started in a state where there is a section in which the setting of the network device 102 such as a switch is erroneously looped, there is a risk that a broadcast storm will occur. Broadcast storm is a phenomenon in which a MAC frame continues to rotate forever in a network. As a result, broadcast frames multiply in the loop to form a storm, and access to the network device 102 constituting the loop from the outside becomes impossible. That is, when a broadcast storm occurs, even if a device such as the management server 101 tries to reset the network device 102 remotely, this cannot be done.

FIG. 17 shows a countermeasure for temporarily blocking a part of the port until the network setting is completed in order to prevent the occurrence of such a broadcast storm. As shown in this figure, the port 441 for connecting the communication cable 411 ₁₉ in the first network device 102 ₁ is temporarily blocked. Further, the port 442 connecting the communication cable 411 ₂₉ in the second network device 102 ₂ is temporarily blocked. Further, a port 443 for connecting the communication cable 411 ₃₅ in the third network apparatus 102 _3, temporarily block the port 444 to connect the communication cable 411 ₄₆ in the fourth network device 102 _4.

FIG. 18 shows a topology as a logical structure after setting a network device such as a switch using a connection module. Each of the ports 441 to 444 is set as a temporary blocking port as a temporarily blocked port. Thereby, the topology of the network is in a state in which no loop is formed as in a range 451 indicated by a one-dot chain line, and the first to ninth network devices 102 _{1 to} 102 ₉ can be set without any problem. After the setting of the _first to ninth network devices 102 _{1 to} 102 ₉ is completed, the construction worker may cancel the temporary blocking port state for the ports 441 to 444.

  According to the second modified example described above, even when there are redundant link connection locations in a configuration in which a plurality of network devices 102 are connected, the interfaces of the network devices 102 at such locations are connected to these networks. Until the setting of the device 102 is completed, the port is logically set in a blocked state. Specifically, transmission of a packet is prohibited to a port for which the network device 102 is set, or a packet received from that port is discarded so that internal transfer of the network device 102 is not performed. As a result, the redundant link connection between the network devices 102 can be temporarily disconnected, so that the cause of communication failure caused by the loop section can be removed.

  In the second modification, even if the network device 102 does not include a port for directly mounting the connection module 104, the connection module itself includes a port for connecting a cable from the outside. The apparatus 102 and the connection module 104 can be connected. As a result, an increase in the cost of the network device 102 to which the present invention is applied can be prevented, and the application range of the invention can be expanded together with the reusable connection module 104. Further, by using both the internal port unit 159 and the external port unit 160, it is possible to reduce the number of connection modules 104 used.

  As described above, the setting of the network device has been described in the embodiment and the modification. However, the present invention can be similarly applied to a terminal or an information device that has an interface port for the network and does not have an interface that can be operated by the user.
