[Problems to be solved by the invention]
By the way, in recent years, various systems such as EDI (Electronic Data Interchange) have been connected by a network to share data in a wide range because of the necessity of sharing information with other companies. Further, in order to realize high reliability of the system, a system configuration of a network is provided with redundancy. For example, when a plurality of small-scale networks exist in one large network, each of the small-scale networks is connected via a router to provide redundancy as a whole network.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a discover map creation system according to an embodiment of the present invention will be described with reference to the drawings. Note that the discover map means a visual display of a connection relationship between a network and a router detected within a set detection range.
[0028]
FIG. 1 is a block diagram of a discover map creation system according to an embodiment. The discover map creation system 2 includes a data control unit 4 that controls data in the discover map creation system 2. The data control unit 4 includes a communication control unit 6 for controlling communication with each node configuring the network to which the discover map creating system 2 belongs, an IP (Internet Protocol) address for setting a detection range, and the like. An input unit 8 for inputting is connected. The data control unit 4 is connected to a data storage unit 10 that stores an IP address and the like input via the input unit 8 and a display unit 12 that displays a created discover map and the like.
[0029]
The data storage unit 10 stores an IP address input via the input unit 8. That is, the input IP address is stored as a range of a network and a router to be detected. The network holds the IP addresses of all routers to which the network is connected. The router holds the IP addresses (network addresses) of all networks to which the router is connected.
[0030]
The data storage unit 10 stores a router detected as being connected to one network as a connection destination of the network. A network detected as connected to one router is stored as a connection destination of the router. The data storage unit 10 stores the created discover map, that is, data for visually displaying a connection relationship between the network and the router detected within the set detection range.
[0031]
Next, a process of creating a discover map performed by the discover map creating system 2 according to this embodiment will be described with reference to the flowchart of FIG. In the following, processing performed in the data control unit 4 of the discover map creation system 2 will be described.
[0032]
First, a range of a network and a router to be detected is set as a detection range (step S10). That is, by inputting a predetermined range of IP addresses through the input unit 8, the range of the network and the router to be detected is set. For example, an IP address such as 192.9.20.38 to 193.2.19.27 is input as a detection range.
[0033]
Next, a network displayed at the top of the discovery map created from the set detection ranges is determined (step S11). For example, when the set detection range includes the network to which the discover map creation system 2 belongs, the network is determined as the network displayed at the top. If the set detection range does not include the network to which the discover map creation system 2 belongs, the network having the smallest value of the network address included in the input IP address is displayed at the top. Is determined as a network to be performed.
[0034]
Next, all the routers connected to the network are detected from the set detection range (step S12). Here, the router is a hardware device that relays between networks, and relays data transmission and reception between networks. For example, in a WAN (Wide Area Network) in which a plurality of LANs (Local Area Networks) are connected to each other, transmission and reception of data between LANs is relayed by a router. The type of router connected to each LAN is detected by using a management protocol such as SNMP (Simple Network Management Protocol).
[0035]
Next, the detected router is stored in the data storage unit 10 as a network connection destination (step S13). That is, it is stored in the data storage unit 10 as a network arrangement. For example, when the routers connected to the network (N1) are the router (R1), the router (R2), and the router (R3), as shown in FIG. (R1, R2, R3) are stored. The detected routers, that is, the router (R1), the router (R2), the router (R4), the router (R5), and the router (R6) are stored as connection destinations of the network (N2). Further, the detected router, that is, the router (R3) and the router (R7) are stored as the connection destination of the network (N3), and the detected router, that is, the router (R4) is stored as the connection destination of the network (N4). ) Is stored.
[0036]
The position information shown in FIG. 3 is a flag indicating whether or not the display position in the discover map has been determined when the discover map is created. The flag is stored. On the other hand, before the display position is determined, the flag of “not arranged” is stored. Here, as for the network (N1), since the position to be displayed as the network to be displayed at the highest level has already been determined, a flag of “placed” is stored as the position information.
[0037]
Next, all the networks connected to the detected router are detected (step S14). That is, each router detects all networks connected to each router based on the detected network address held by each router.
[0038]
Next, the detected network is stored in the data storage unit 10 as a connection destination of the router (step S15). That is, the data is stored in the data storage unit 10 as a router array. For example, the network (N1) and the network (N2) are connected to the router (R1), and the network (N1) and the network (N2) are connected to the router (R2). It is assumed that the network (N1) and the network (N3) are detected as the networks connected to. In this case, as shown in FIG. 4, the network (N1) and the network (N2) are connected to the router (R1), and the network (N1) and the network (N2) are connected to the router (R2). However, the network (N1) and the network (N3) are stored as connection destinations of the router (R3).
[0039]
Similarly, the detected network, that is, the network (N2) and the network (N4) are stored as the connection destinations of the router (R4). The detected network, that is, the network (N2) is stored as the connection destination of the router (R5). Further, the detected network, that is, the network (N2) is stored as the connection destination of the router (R6), and the detected network, that is, the network (N3) is stored as the connection destination of the router (R7).
[0040]
Next, a discover map is created with reference to the network arrangement and the router arrangement stored in the data storage unit 10 (step S16). That is, first, among the networks stored in the network arrangement shown in FIG. 3, the display position of the router stored as the connection destination of the network (N1) displayed at the highest position of the discover map is determined. . Here, since the network (N1) is the network displayed at the highest level, the display position of the router to which the network (N1) is connected, that is, the router (R1), the router (R2), and the router (R3) are displayed. Is determined as the lower display position of the position where the network (N1) is displayed. Here, the arrangement of the routers at the display position is determined in accordance with the number of networks connected to each router, from the left in the order of the number of networks connected, from the left, but as shown in FIG. The number of networks connected to the router (R1), the router (R2), and the router (R3) are equal. Therefore, for example, it is determined that the router (R1), the router (R2), and the router (R3) are to be displayed horizontally from the left end to the right end at the lower display position in the order of ascending IP address values.
[0041]
Here, since the display positions of the router (R1), the router (R2), and the router (R3) have been determined, the “not arranged” flag stored in the position information as shown in FIG. Is changed to the flag.
[0042]
Further, as shown in FIG. 4, in the router arrangement, the network (N1), the network (N2), and the network (N1) and the network (N2) as the connection destinations of the router (R1) are connected to the router (R1). ), The network (N1) and the network (N3) are stored as connection destinations of the router (R3). At this time, as shown in FIG. 3, a flag of “placed” is stored as the position information of the network (N1). That is, it is already determined that the network (N1) is displayed at the upper display position of the position where the router (R1), the router (R2), and the router (R3) are displayed. Therefore, the network (N2) and the network (N3) whose display positions have not yet been determined are displayed in the lower display position below the positions where the router (R1), the router (R2), and the router (R3) are displayed. Is determined.
[0043]
Here, the number of connected routers differs between the network (N2) and the network (N3) as shown in FIG. That is, the router (R1), the router (R2), the router (R4), the router (R5) and the router (R6) are connected to the network (N2), and the router (R3) is connected to the network (N3). Two routers (R3) and router (R7) are connected. At this time, the "placed" flag is stored in the position information of each of the router (R1), the router (R2), and the router (R3) as shown in FIG. That is, it is determined that the image is displayed at the upper display position extending in the horizontal direction above the display position of the network (N2) and the network (N3). Accordingly, the routers whose positions to be displayed are not determined are the router (R4), the router (R5), the router (R6), and the router (R7). Among these routers, the router is connected to the network (N2). The routers are the router (R4), the router (R5), and the router (R6), and the router connected to the network (N3) is the router (R7).
[0044]
Accordingly, in the lower display position of the position where the router (R1), the router (R2), and the router (R3) are displayed, the display position of the network (N2) having a large number of connected routers is the left end, and the network (N2) Is the display position of the network (N3) on the right side in the horizontal direction. Then, as shown in FIG. 5, the "unarranged" flag stored in the location information of the network (N2) and the network (N3) is changed to the "arranged" flag.
[0045]
Next, the display positions of the router connected to the network (N2) and the router connected to the network (N3) are determined. At this time, among the routers connected to the network (N2) and the routers connected to the network (N3), the "placed" flag is included in the position information of the routers (R1) to (R3). It is remembered. That is, it is determined that the network (N2) and the network (N3) are displayed at the upper display position of the display position where the network (N3) is displayed. On the other hand, the display positions of the routers (R4) to (R7) are not determined. Therefore, it is determined that these routers (R4) to router (R7) are to be displayed at the lower display position of the display position where the network (N2) and the network (N3) are displayed.
[0046]
Here, as shown in FIG. 4, the network (N2) and the network (N4) are connected to the router (R4). The network (N2) is connected to the router (R5), the network (N2) is connected to the router (R6), and the network (N3) is connected to the router (R7). Accordingly, the router having the largest number of connected networks, that is, the display position of the router (R4) is the left end, and the display position on the right side in the horizontal direction of the router (R4) is sequentially the router (R5), the router (R6), and the router. It is determined as the display position of (R7). Further, the “unplaced” flag stored in the position information of the router (R4) to the router (R7) is changed to the “placed” flag.
[0047]
Next, the display position of the network connected to any of the routers (R4) to (R7) is determined. At this time, among the networks connected to the routers (R4) to (R7), the networks (N2) and (N3) are located above the display position where the routers (R4) to (R7) are displayed. Has been determined to be displayed at the upper display position extending horizontally. Therefore, it is determined that only the network (N4) is displayed in the lower display position of the display positions of the routers (R4) to (R7). Further, the “unarranged” flag stored as the location information of the network (N4) is changed to the “arranged” flag.
[0048]
Then, the positions at which all networks and routers are displayed are determined, that is, when the “placed” flag is stored as the position information of all networks and routers, the networks and routers are displayed at the respective display positions. In addition to the display, the connected network and the router are connected by a line to indicate the connection relationship between the network and the router.
[0049]
Next, the discover map created in step S16 is displayed on the display unit 12 (step S17). That is, as shown in FIG. 7, a connect map is displayed on the display unit 12 by connecting the connected network and the router with a line to display the connection relationship between the network and the router. When displaying the discover map, for example, a line connecting the network (N2) to the router (R4), the router (R5), and the router (R6) is connected to the network (N3) and the router (R7). It is determined whether or not the line intersects. When it is determined that the lines intersect, a predetermined interval is provided between the network (N2) and the network (N3) so as not to intersect, and adjustment is performed so that intersection of the connection does not occur. indicate.
[0050]
The discover map creation system according to this embodiment detects routers connected to one network, and displays only those routers that have not been displayed among the detected routers. It is displayed horizontally in the lower display position of the position. In addition, the network connected to the detected router is detected, and only the networks not yet displayed among the detected networks are displayed horizontally in a lower display position of the display position where the router is displayed. I have. Therefore, the router connected to the network is always displayed at the upper display position or the lower display position of the display position where the network is displayed. The network connected to the router is always displayed at the upper display position or the lower display position of the display position where the router is displayed. Therefore, by connecting the network and the router with a line, the connection relationship between the network and the router can be arranged vertically and horizontally and a discover map that can be easily understood visually can be displayed.
[0051]
In addition, all the routers or networks connected to the network or the router are horizontally arranged in the upper display position or the lower display position of the display position where the network or the router is displayed in the descending order of the number of the connected routers or networks. Displayed in the direction. Therefore, it is possible to display a simple discover map in which the intersection of the connection between the network and the router is eliminated.
[0052]
Further, all the routers or networks connected to the network or the router are detected in the set detection range, and the display position is determined. Therefore, even in the case of a network having a complicated configuration having redundancy, it is possible to display a discover map from which the configuration of the entire network can be quickly and accurately grasped.
[0053]
In the discovery map creation system according to the above-described embodiment, the discovery map is created after detecting all networks and routers within the set detection range, but the detection and creation of the discovery map are performed in parallel. May be performed. For example, when the network (N1) displayed at the highest level is determined and a router connected to the network (N1) is detected, the display position of the detected router is displayed on the network (N1). This is the lower display position of the position. In this way, the display position may be determined each time a router or a network is detected, and a discover map may be created.
[0054]
In addition, the above-described discover map creation system can cause the computer to function so that the above-described discover map creation processing can be performed by inputting the discover map creation program to the computer via the input unit. In addition, by downloading the discover map creation program via a network such as the Internet and incorporating the program into the computer, the computer can function so that the above-described discover map creation processing can be performed.
