DETAILED DESCRIPTION OF THE INVENTION
In the following, an embodiment of the present invention will be described with reference to an example of a network environment as shown in FIG.
[0014]
In FIG. 2, reference numeral 200 is an image of the outer wall of a building. This building is assumed to be used by the sales department of a company. Reference numerals 201 to 203 denote areas used by the sales department 1 to the sales department 3 of the sales department, respectively. A rectangle described in each use area, for example, 211 or 212, indicates a network device. In particular, reference numeral 211 denotes a server having a function for automatically creating a network physical configuration diagram. A rectangle described as “PC-****” such as 212 indicates a terminal device provided with a Web browser (WWW browser).
[0015]
FIG. 1 shows a schematic configuration of the network physical configuration diagram automatic creation system of the present embodiment. The entire system 101 includes a client PC 102 (corresponding to each of PC-0001 to PC-0010 in FIG. 2) and a server PC 103 (corresponding to the server 211 in FIG. 2). Each client PC 102 has a Web browser function, and an area information input screen 104 is displayed on the Web browser. This screen will be described in detail later. The server PC 103 includes an input information processing unit 105, a change management database 106, a device pattern arrangement processing unit 107, a network configuration information database 108, a network configuration diagram drawing processing unit 109, a display device 110, and a connection configuration search function unit 111. ing.
[0016]
In this system, first, the logical configuration information of the network is collected by the connection configuration search function unit 111. The connection configuration search function unit 111 has an existing network configuration analysis function, collects MIB information of network devices using SNMP, and detects devices present in the network. Also, the connection relation between devices is analyzed based on the history information of data sent from the communication port to other devices and the data transfer setting information of the network relay device. The connection configuration search function unit 111 registers the detected device information as device data 108B of the network configuration information database 108. The connection configuration search function unit 111 registers the connection information between the analyzed devices as connection information data 108C. In this way, the network configuration information database 108 stores the presence information of network devices and the connection information between devices.
[0017]
The area data 108A of the network configuration information database 108 stores the shape data of each area as shown in 201 to 203 in FIG. Further, the floor layout data 108D stores the layout of these areas and the floor layout of the walls, pillars, desks, etc. of the building.
[0018]
Next, a user who uses each client device opens the area information input screen 104 by specifying the URL of the area information input screen 104 from a Web browser running on the client devices PC-0001 to PC-0010 in FIG. On the area information input screen 104, the user inputs the device name of the client device and the area name of the area where the device is physically located.
[0019]
Information on the device name and area name input by the user on the area information input screen 104 is sent to the input information processing unit 105 by HTTP. The input information processing unit 105 stores the device name and area name in the change management database 106 as area change result data 106A. The equipment pattern arrangement processing unit 107 has a timer function and periodically refers to the change management database 106. When the area change result data 106A is stored in the change management database 106, the device pattern arrangement processing unit 107 searches the area data 108A in the network configuration information database 108 from the area name of the area change result data 106A. The equipment pattern arrangement processing unit 107 calculates an empty area on the area from the information of the area data 108A and the equipment data 108B, and determines the arrangement place of the equipment pattern. Thereafter, the device pattern arrangement processing unit 107 stores the device pattern arrangement information in the device data 108B, and deletes the area change result data 106A from the change management database 106.
[0020]
Thereafter, when the user instructs the network configuration diagram drawing processing unit 109 to refer to the layout drawing, the network configuration diagram drawing processing unit 109 reads the device data 108B, the inter-device connection data 108C, and the floor from the network configuration information database 108. The layout data 108D is read and each data is drawn on the display device 110.
[0021]
Next, the system shown in FIG. 1 will be described in more detail.
[0022]
First, the area information input process will be described. FIG. 7 is a sequence diagram showing the flow of processing when inputting area information. A user 701 indicates a user operation or a display screen in each client device. An area information input screen 702 shows processing of the Web browser of the client device. The input information processing unit 703 indicates processing of the input information processing unit 105 of the server 103 illustrated in FIG. The input information processing unit 105 has a WWW server function. The network configuration information database 704 and the change management database 705 correspond to the network configuration information database 108 and the change management database 106 in FIG.
[0023]
The user designates the URL of the area information input screen from the Web browser set up in advance in the client device (711). The Web browser requests a page from the input information processing unit 105 of the server 103 according to the input URL (712). The input information processing unit 105 transmits the area information input screen 104 to the Web browser of the client device in response to the page request (715). At this time, the input information processing unit 105 refers to the area data 108A of the network configuration information database 108, creates a list of area names, and sets it in the area information input screen 104 (713, 714). The area information input screen 104 transmitted (715) from the input information processing unit 105 to the Web browser is displayed on the Web browser (716).
[0024]
FIG. 3 shows a display example 300 of the area information input screen 104. The area information input screen 300 includes a column 301 for inputting a device name and a column 302 for selecting an arrangement area. In a column 302 for selecting an arrangement area, a list of areas currently registered on the system is displayed (list box format). Such an area information input screen 300 may be created by Java Applet, Servlet or JSP (JAVA is a registered trademark of Sun Microsystems, Inc.).
[0025]
Returning to FIG. 7 again, when the user inputs the device name 301 and the arrangement area 302 on the area information input screen 104 (300) and presses the send button (717), the information on the device name and the arrangement area is the area information. It is sent to the input information processing unit 105 by HTTP through the input screen 104 (718). The input information processing unit 105 adds the received information to the change management database 106 as a record of the area change result data 106A (719). When the record is successfully added (720), the input information processing unit 105 sends the registration completion page data to the Web browser of the client device (721). The user sees the registration completion page (722) displayed on the web browser and recognizes that the registration is completed.
[0026]
FIG. 4 shows a data storage format in the area change result data 106A. A device name 401 of each client device and an area name 402 where the device is arranged are stored in association with each other.
[0027]
Next, a method in which the device pattern arrangement processing unit 107 determines the arrangement of the device pattern based on the area change result data 106A will be described. FIG. 5 is an explanatory diagram of a method for determining the arrangement of the device pattern.
[0028]
Reference numeral 501 in FIG. 5A denotes an area of “Sales Section 3” corresponding to 203 in FIG. It is assumed that device pictures of some devices are already arranged in each area, and the device images arranged are stored in device data 108B as shown in FIG. In FIG. 6, center coordinates X602 and center coordinates Y603 stored for each device name 601 indicate position coordinates at which the center of the pattern is displayed when the device pattern representing the device is displayed in the area.
[0029]
With reference to FIG. 5, a method for obtaining an arrangement position for adding a device pattern of a new device to the area “Sales Section 3” 501 will be described. First, the minimum circumscribed rectangle 502 circumscribing this area 501 is obtained. Next, the circumscribed rectangle 502 is divided by a certain size and divided into small divided areas 503 having a grid shape. Next, as shown in FIG. 5B, only the internal region 505 (shaded portion) in which the center point 504 of the divided region is inside the area 501 is selected from these divided regions 503. Next, as shown in FIG. 5C, the coordinates of the divided areas are checked in order from the upper left internal area 506, and the center coordinates 602 and 603 are the internal coordinates of the equipment picture of the equipment stored in the equipment data 108B. Check to see if there is anything in the region. For example, when the device picture included in the upper left internal area 506 in FIG. 5C is not in the one stored in the device data 108B, it means that the device picture of the new device can be arranged at that position. The center point of the equipment pattern to be newly placed is placed so as to overlap the center point of the internal region 506. If a device pattern stored in the device data 108B is found in the upper left internal region 506, the next internal region 507 (FIG. 5D) is displayed in order from left to right. Investigate. If an empty area is not found even after examining the inner area at the right end, each inner area is examined again from the inner area at the left end one stage below. If there is no other device placed in this way, and an area is found that does not overlap with another device even if a new device is placed at that location, the device is placed in that area. To do.
[0030]
As a result of repeating such processing, when there is no space in the internal area as indicated by 508 in FIG. 5E, the vertical and horizontal lengths of the internal area are halved as shown in FIG. Thus, a smaller divided area 509 is created. Thereafter, in the same manner as described with reference to FIGS. 5A to 5E, the selection of the internal area, the search for a free space in the internal area, the determination of the overlap with other devices at the arrangement destination, and the arrangement of the device pattern repeat. As a result of searching for an empty area in this way, the device picture is arranged as indicated by 510 in FIG. Information on the device whose arrangement has been determined is stored in the network configuration database 108 as device data 108B.
[0031]
FIG. 8 shows a flowchart of processing in which the device pattern arrangement processing unit 107 determines the arrangement of device patterns. In step 801, the equipment pattern arrangement processing unit 107 counts the number of records in the area change result data 106A of the change management database 106. If the number of records in the area change result data 106A is 0, it means that there is no device pattern to be added to the area, and the process is terminated as it is. If the number of records in the area change result data 106A is not 0, in step 802, the first record of the area change result data 106A is read. In step 803, the equipment pattern arrangement processing unit 107 reads information on the area indicated by the read area change result data from the area data 108A.
[0032]
Thereafter, the equipment pattern arrangement processing unit 107 determines the arrangement of the equipment pattern on the area by the processing method described in FIG. 5 in steps 804 to 811. Note that the array posA [i] created in step 805 is arranged in the order of processing of the divided areas (from left to right, and when it reaches the right end, go down one step and again from left to right). . The array posB [i] created in step 806 is obtained by extracting the internal area described above from the divided areas, and is also arranged in the order of processing. Steps 807 to 810 are processing for searching for a free area from the internal area posB [i]. If there is a vacancy, in step 811 a new device picture is arranged there. If there is no space, the height X and width Y of the rectangle that divides the circumscribed rectangle are halved and the process returns from step 808 to 805 to repeat the processing. When the device pattern is arranged in step 811, in step 812, the top record of the processed area change result data 106A is deleted and the process returns to the top of the whole process until the number of area change result data records becomes zero. Repeat the above process.
[0033]
Next, a method for drawing a network configuration diagram will be described. The user requests the system to display a network configuration diagram as necessary. FIG. 9 shows a processing procedure in which the network configuration diagram drawing processing unit 109 draws a layout diagram on the display 110.
[0034]
In response to the user request, the network configuration diagram drawing processing unit 109 first reads the floor layout data 108D in step 901. In step 902, the network configuration diagram drawing processing unit 109 draws the background of the layout diagram (building wall, pillar, desk, etc.) based on the read floor layout data 108D. Next, the network configuration diagram drawing processing unit 109 reads the device data 108B in step 903, and draws the design of the device on the background based on the arrangement coordinates of the device data 108B in step 904. Finally, the network configuration diagram drawing processing unit 109 reads the inter-device connection data 108C in step 905, and draws a straight line between the centers of the device patterns registered in the inter-device connection data 108C in step 906.
[0035]
