Description

TECHNICAL FIELD
• The invention relates to a computer network and, more particularly, to a network device management system according to network device management software for managing a network device connected to a computer network.
BACKGROUND ART
• TCP/IP Protocol is a protocol for managing a network such as an SNMP (Simple Network Management Protocol). At present, TCP/IP Protocol is not limited for TCP/IP based networks but is also widely used as a network management protocol of a network based on a protocol other than the TCP/IP.
• Usually, in the network management based on the SNMP, an MIB (Management Information Base) which a network device (agent) as a management target has is accessed by using the SNMP protocol from a PC (manager) for managing the network device, thereby making management. The MIB has a data structure like a tree and identifiers such as object IDs which can be unconditionally identified have been allocated to all nodes. Such a structure of the MIB is called SMI (Structure for Management Information) and has been specified in RFC1155, “Structure and Identification of Management Information for TCP/IP-based Internets”.
• As a method for efficiently finding various resources (printer, copying apparatus, server, scanner, etc.) on the network and using them, a method called a directory service has been provided. The directory service is, as it were, a directory (telephone book) regarding the network and used to store various information. As specific examples of the directory service, there are an LDAP (Lightweight Directory Access Protocol) specified in RFC1777 and an NDSk (Netware Directory Service) of Novell Co., Ltd. In the case of an environment in which the directory service cannot be used, the network device can be searched by using SNMP broadcast.
• In a conventional network device management system, for example, the network device connected to the network can be searched by using the SNMP/MIB or the directory service and a state of the network device and various information set in the network device can be displayed and changed.
• In recent years, a Web application has vigorously been developed so that the following effects are obtained: the user can access network management information unitarily managed on a server PC (server computer) from a plurality of client PCs (client computers) via a Web browser, browse a list of the network devices connected to the network, browse and change the states of the network devices and various information set therein, and the like. In this instance, the Web server and the Web browser communicate by an HTTP (Hyper Text Transfer Protocol).
• As one of functions of such a Web application, there is a function of arranging and displaying icons (device icons) indicative of the network devices as management targets onto a virtual map so that actual installing locations of the network devices can be recognized. In the specification, such a function or the map formed by the function is called a “device map”. Such a function is effective at the time of confirming the installing locations of the network devices in case of occurrence of an error (for example, paper jam or absence of paper) such that the user or an administrator of the network has to go to the installing location of the failed network device as a management target and take some measures, or the like.
DISCLOSURE OF INVENTION
• In the above conventional example, however, since the list of the network devices and one or a plurality of device maps formed every installing location have independently been displayed, in the cases where there are a plurality of device maps, a number of devices are arranged on the device map, or the like, it is difficult to examine in which location of which device map the desired network device has been arranged.
• To solve the above problem, therefore, the invention is characterized in that in which location of which device map identification information of a designated network device has been arranged is displayed to the user so that he can easily and quickly grasp it.

Those apparatuses are equipped with network interface cards or the like, so that they are connected to theLAN100, respectively. The network devices are not limited to them but other apparatuses which can be connected to the network can be used.
• Those network devices are network devices which can be managed by the network device management system. They can be searched by a method such as a directory service or the like and information can be obtained and set by the SNMP/MIB.
• Reference numerals105ato105edenote PCs (Personal Computers) which can be connected to the network. Those PCs are PCs on which the network device management software according to the invention can operate. In the case where the network device management system according to the invention has been constructed by the Web server and the Web browser, the network device management software and the Web server operate on one of the server PCs and the Web browser operates on other PCs (client PCs). The Web browser accesses the network device management software which is operating on the server PC, thereby enabling the user to use the network device management system.
• FIG. 2 is a block diagram showing an example of a construction of a PC on which network device management software according to the invention can operate. InFIG. 2,reference numeral200 denotes a PC on which the network device management software operates and it is similar to thePCs105ato105einFIG. 1. The PC200 has aCPU201 for executing the network device management software which has been stored in aROM202 or an HD (hard disk)211 or which is supplied from an FD (floppy disk drive)212, a CD (CD-ROM drive)213 or a DVD (DVD-ROM drive)214. The PC200 integratedly controls devices which are connected to asystem bus204.
• Reference numeral203 denotes a RAM which functions as a main memory, a work area, or the like of theCPU201;205 a KBC (keyboard controller) for controlling an instruction input from a KB (keyboard)209, a pointing device (not shown), or the like;206 a CRTC (CRT controller) for controlling a display of a CRT (CRT display)210; and207 a DKC (disk controller) for controlling accesses to theHD211, FD212,CD213, andDVD214 for storing a boot program, various applications, an edition file, a user file, the network device management software, and the like.
• Reference numeral208 denotes an NIC (network interface card) for bidirectionally transmitting and receiving data to/from other network device via theLAN100.
• In all descriptions which will be made hereinbelow, a substance of execution on hardware is theCPU201 and a substance of control on software is the network device management software installed onto the HD (hard disk)211, unless otherwise specified.
• Examples of various display screens which are displayed by the network device management system according to the invention will be described hereinbelow.
• FIG. 3 shows an example of a device list (list of devices) which is displayed by the network device management system according to the invention. As shown in the diagram, in this example, among the network devices connected to theLAN100, thecolor printer101a, theprinters102aand102b, and thehybrid apparatuses103ato103care displayed on adevice list300.
• In the device list, (1) the network devices searched by a searching procedure using the MIB/SNMP according to the network device management system, (2) the partial network devices selected from the searched network devices, (3) the network devices manually registered into the network device management system, and the like are displayed in a list format.
• In the diagram,reference numeral306 denotes a dropdown list box for switching a display format. Since “list” is selected at present, the network devices are displayed in a list format. By selecting “map format” in thedropdown list box306, adevice map500 or600, which will be explained hereinlater, can be displayed.
• As information of each network device, adevice name301, aproduct name302, aninstalling location303, and anetwork address304 are displayed on thedevice list300.
• Further, a link305 (to a device map) to display the device map on which icons indicative of the corresponding network devices have been arranged is displayed in an area of the installinglocation303. In this example, thelink305 to display device maps of arranging destinations is displayed for thecolor printer101a, thehybrid apparatus103c, and theprinters102aand102b. This link is a button for displaying the devices.
• InFIG. 3, specifically, information corresponding to101a,103a,103b,103c,102a, and102binFIG. 1 is displayed in each line.
• When the user clicks thelink305, the device map corresponding to the link is displayed. For example, in thedevice list300, when thelink305 to the device map displayed in the area of the installinglocation303 of theprinter102ais clicked, adevice map700 shown inFIG. 7, which will be explained hereinlater, is displayed.
• FIG. 4 shows an example of a display screen which is displayed when a specific one of the network devices displayed in thedevice list300 inFIG. 3 is selected.FIG. 4 shows an example of a device management page which is displayed when theprinter102ais designated.
• Although the page in which the information for identifying mainly the network devices has been displayed is shown in this example, it can be switched to another page (not shown) in order to display other information (error state, equipment information, network information, job information, etc.).
• InFIG. 4, adevice name401, an installinglocation402, a tonercartridge type number403, aproduct name404, and the like are displayed as information regarding theprinter102ain adevice management page400. Further, alink405 to a device map on which the icon indicative of theprinter102ahas been arranged is displayed in an area of the installinglocation402. When the user clicks thelink405 to the device map, thedevice map700 shown inFIG. 7, which will be explained hereinlater, is displayed.
• This link is displayed only when the icons have been arranged on the device map, thereby making it possible to prevent a situation such that the user unnecessarily displays the device map in spite of the absence of the corresponding device map.
• FIGS. 5 and 6 show examples of device maps which are displayed by the network device management system according to the invention. The icon indicative of theprinter102a, the icon indicative of thehybrid apparatus103c, and icons for moving to another device map among the network devices connected to theLAN100 inFIG. 1 have been arranged inFIG. 5.
• The icon indicative of thecolor printer101a, the icon indicative of theprinter102b, and icons for moving to another device map among the network devices connected to theLAN100 inFIG. 1 have been arranged inFIG. 6.
• In the diagrams,reference numerals501 and601 denote dropdown list boxes for switching the display format to display the network devices. By selecting “list format” in thedropdown list box501 or601, thedevice list300 can be displayed.
• Further,reference numerals502 and602 denote dropdown list boxes for selecting the device map to be displayed. When “1st Floor” is selected, the device map corresponding to the first floor is displayed. In this instance, the device maps500 and600 can be switched in the dropdown list boxes.
• FIG. 7 shows an example of a device map which is displayed by the network device management system according to the invention.FIG. 7 differs fromFIG. 5 with respect to a point that the icon of theprinter102bis surrounded by a quadrangle and emphasis-displayed. That is,FIG. 7 shows the example of the device map which is displayed in the case where the link to the device map associated with each device is clicked.
• Thedevice map700 inFIG. 7 is displayed in the case where, in thedevice map300 shown inFIG. 3, thelink305 to the device map displayed in the device information display area of theprinter102ais clicked or in the case where thelink405 to the device map displayed on thedevice management page400 of theprinter102ashown inFIG. 4 is clicked.
• Although the emphasis display is made by surrounding the icon by the quadrangle, it can be made in another form such that the color of the icon is changed, the icon flickers, or the icon is enlarged.
• In the invention, the process for displaying thelinks305 and405 to the device map to thedevice list300 shown inFIG. 3 and thedevice management page400 shown inFIG. 4, respectively, and the emphasis displaying process of the device icon (icon indicative of the network device) in thedevice map700 shown inFIG. 7 will be explained hereinlater with reference to flowcharts.
• FIG. 8 is a flowchart showing an example of the process in the case where thelink305 to the device map is displayed to thedevice list300 shown inFIG. 3.
• In the flowchart, in step S801, a value of a variable i to count the number of devices which are displayed in the device list is initialized to 0. Step S802 follows. The value of the variable i becomes an index value which starts from 0 and is used to refer to each network device in the following processes.
• In step S802, the value of the variable i is compared with the number of devices which are displayed in the device list. If the value of the variable i is smaller than the number of devices, step S803 follows (YES in step S802). Otherwise, the processing routine is finished (NO in step S802).
• In step S803, information regarding the network device (the ith network device) in which the value of the variable i is used as an index is displayed in a display area of the device information. Step S804 follows. The device information which is displayed here is information obtained from the network device when the network device as a management target is searched (for example, a device name, a product name, an installing location, a network address, an MAC address, etc.) and information held in the network device management system with respect to the network device as a management target (for example, a print speed, print resolution, etc.). The information which is displayed can be changed every user.
• In step S804, the device map on which the network device using the value of the variable i as an index has been arranged is searched in accordance with a procedure shown inFIG. 10, which will be explained hereinlater. In step S804, it is assumed that if the device map on which the icon showing the network device has been arranged is searched, the information (for example, the ID of the device map) to identify the device map on the arranging destination side is returned.
• In step S805, whether the device map on which the icon showing the network device has been arranged has been detected in step S804 or not is discriminated. If the device map has been detected, step S806 follows (YES in step S805). Otherwise, step S807 follows (NO in step S805). Whether the device map has been detected or not can be confirmed by checking whether the ID information to identify the device map has been returned or not.
• In step S806, on the basis of the ID information to identify the device map obtained in the process in step S804, the link to display the device map shown by the ID information is displayed in the display area of the device information.
• In step S807, 1 is added to the value of the variable i and step S802 follows.
• By this process, the information regarding the network device is displayed to each network device. If the icon showing the network device has been arranged on one of the device maps, the link to this device map can be displayed.
• FIG. 9 is a flowchart showing an example of a process in the case where thelink405 to the device map is displayed to thedevice management page400 shown inFIG. 4.
• In the flowchart, in step S901, information which is displayed to thedevice management page400 is obtained by using the MIB/SNMP from the network device serving as a management target of the device management page, that is, from the network device selected from the device list. In the example ofFIG. 3, thedevice name401, installinglocation402, tonercartridge type number403,product name404, and the like are obtained from the network device.
• In step S902, the information obtained from the device in step S901 is displayed. In step S903, the device map on which the icon showing the network device serving as a management target of the device management page has been arranged is searched in accordance with the procedure shown inFIG. 10, which will be explained hereinlater. In this process, it is assumed that if the device map on which the device icon has been arranged has been detected, the information (for example, ID of the device map) to identify the detected device map is returned.
• In step S904, whether the device map on which the device icon of the device serving as a management target of the device management page has been arranged has been detected in step S903 or not is discriminated. If the device map has been detected, step S905 follows (YES in step S904). Otherwise, the processing routine is finished (NO in step S904).
• In step S905, on the basis of the information to identify the device map obtained in the process in step S903, the link to display the detected device map is displayed in the display area of the device information. In the example of thedevice management page400 shown inFIG. 4, thelink405 to the device map is displayed in the area for displaying “installing location” in the display area of the device information.
• FIGS. 8 and 9 show a displaying process of the network device management software in the case where the network device management software is activated in each PC.
• However, in the case where the network device management software and the Web server are activated by the server PC and the Web browser activated in each client PC accesses the network device management software, the “displaying process” inFIG. 8 denotes the process such that the network device management software on the server PC embeds the information to be displayed on the Web page which is provided to the Web browser via the Web server. That is, if the Web page is described by a language such as HTML (Hyper Text Markup Language), XML (eXtensible Markup Language), or the like, the information regarding the network device or the link to the device map is described on the Web page. The network device management software transmits the data of the formed Web page to the Web browser via the Web server.
• FIG. 10 is a flowchart showing an example of a process for searching the device map on which the device icons have been arranged, and this process is executed in step S804 inFIG. 8 and in step S903 inFIG. 9.
• InFIG. 10, in step S1001, the ID information to identify the network device which is designated when this process is activated and serves as a processing target of the process is stored. As ID information to identify the network device, for example, the MAC address or the like is generally used. However, another ID information can be used.
• In step S1002, information (device map management information) to manage the device map formed in the edition page of the device map is read out.FIG. 12 shows an example of the device map management information which is read out here. In the diagram, reference numeral shown at the left edge of each line indicates a line number added for the purpose of simply explaining. In the diagram, the number of device maps has been stored online2, an ID and a name of the first device map have been stored on lines4-6, and an ID and a name of the second device map have been stored on lines8-10, respectively.
• In the example, it will be understood that there are two device maps, the ID of the first device map is equal to 1, its name is “1st Floor”, the ID of the second device map is equal to 2, and its name is “2nd Floor”. The ID of the device map is used to access construction information (device map construction information) of each device map, which will be explained hereinlater, and identify the device map which is displayed when the link to the device map is clicked.
• In step S1003, a value of a variable m to count the number of device maps is initialized to 0. The value of the variable m becomes an index value which starts from 0 and is used to refer to each device map in the following processes.
• In step S1004, the value of the variable m is compared with the number of device maps. If the value of the variable m is smaller than the number of device maps, step S1006 follows (YES in step S1004). Otherwise, step S1005 follows (NO in step S1004).
• In step S1005, a message showing that the device map on which the device icon of the designated network device has been arranged does not exist is returned as a result of the process. The processing routine is finished.
• In step S1006, a list of the network devices arranged on the device map using the variable m as an index is obtained. It is now assumed that the construction information (device map construction information) of each device map has individually been stored in the file which can be identified by the ID of the device map shown inFIG. 12.FIGS. 13 and 14 show examples of the device map construction information.
• FIG. 13 shows construction information of the device maps shown inFIGS. 5 and 7. In the diagram, reference numeral shown at the left edge of each line indicates a line number added for the purpose of simply explaining. In the diagram, a size of device map has been stored online1 and a name of an image file which is displayed as a background of the device map has been stored online2. The image file which is displayed as a background of the device map is an image showing an outline of the installing locations. For example, in the device map ofFIG. 5, an image showing desks, chairs, and passages is expressed in the image file. By arranging the icons showing the network devices onto the outline of the installing locations shown by the image file, in which locations in a room or a building the network devices have been installed can be easily confirmed.
• Information regarding the various icons arranged on the device map has been stored in line3 and subsequent lines. Information of a map icon to jump to another device map has been described in lines3-4. Information of a Web icon to jump to another Web site has been described in lines5-6 and lines7-8.
• Information of device icons to jump to the device management page has been described in lines9-12 and lines13-16. Information regarding the devices associated to the device icons has been stored in the information of the device icons stored in lines9-12 and lines13-16. By comparing the information stored here with the information for identifying the network devices stored in step S901, whether the icons indicative of the network devices as processing targets have been arranged on the device map or not can be discriminated. By counting the number of stored information of the device icons, the number of network devices arranged on the device map can be obtained.
• Further, coordinate data (XPOSITION, YPOSITION) showing the arranging position, a title (DEVICE TYPE, NAME, MODEL) which is displayed in a form such that it is annexed to the icon, and the like are also included in each of the information regarding the icons.
• Similarly,FIG. 14 shows construction information of the device map shown inFIG. 6. A size of device map has been stored inline1. A name of the image file which is displayed as a background of the device map has been stored inline2.
• Information regarding various icons arranged on the device map has been stored in line3 and subsequent lines. Information of a map icon to jump to another device map has been described in lines3-4. Information of a Web icon to jump to another Web site has been described in lines5-6 and lines7-8.
• Information of the device icons to jump to the device management page has been described in lines9-12 and lines13-16.
• An explanation ofFIG. 10 will be continued. In step S1007, a value of a variable n to count the number of devices arranged on the device map using the variable m as an index is initialized to 0. The value of the variable n becomes the index value starting from 0 for referring to each of the network devices arranged on the device map using the variable m as an index in processes, which will be explained hereinlater.
• In step S1008, the value of the variable n is compared with the number of network devices arranged on the device map. When the value of the variable n is smaller than the number of network devices, step S1010 follows (YES in step S1008). Otherwise, step S1009 follows (NO in step S1008).
• In step S1009, “1” is added to the value of the variable m and step S1004 follows.
• In step S1010, the information of the network device using the variable n as an index is compared with the ID information of the device stored in step S1001. If the nth network device coincides with the designated network device, step S1011 follows (YES in step S1010). Otherwise, step S1012 follows (NO in step S1010).
• In step S1011, a search result showing that the device map on which the designated network device has been arranged exists and the information (for example, ID of the device map) to identify the device map are returned as a processing result. The processing routine is finished.
• In step S1012, “1” is added to the value of the variable n and step S1008 follows.
• By the above processes, if the icon showing the network device has been arranged on one of the device maps, the device map on the arranging destination side is specified and the information to identify the device map on the arranging destination side, for example, the device map ID can be provided.
• FIG. 11 is a flowchart showing an example of a process in the case of displaying the device map shown inFIGS. 5,6, and7. The icon showing the specific network device is also emphasis-displayed.
• The processing routine shown inFIG. 11 is activated when there is a display request of the device map. When the display request is made, the information (for example, ID of the device map) to identify the device map to be displayed and, if the network device which needs to be emphasis-displayed exists, the information (for example, the MAC address) to identify such a network device are designated.
• For example, if the link to the device map is clicked and the device map is displayed, the network device to be emphasis-displayed is designated. In other methods (for example, in the case where in thedevice list300 inFIG. 3, “map format” is selected from thedropdown list box306 and the device map is displayed), the network device to be emphasis-displayed is not particularly designated.
• InFIG. 11, in step S1101, whether the network device which needs to be emphasis-displayed has been designated at the time of the display request of the device map or not is discriminated. If the network device has been designated, step S1102 follows (YES in step S1101). Otherwise, step S1103 follows (NO in step S1101). In step S1102, the ID information of the network device which needs to be emphasis-displayed and has been designated at the time of the display request of the device map is stored.
• In step S1103, the construction information (for example, data shown inFIGS. 13 and 14) of the device map to be displayed is obtained. In step S1104, an image of the background of the device map is displayed on the basis of the image file designated by the construction information of the device map.
• Further, the icons are displayed in step S1105 and subsequent steps. First, in step S1105, a value of a variable k to count the number of icons arranged on the device map is initialized to 0. The value of the variable k becomes an index value which starts from 0 and is used to refer to the information of each of the icons arranged on the device map to be displayed in the following processes.
• In step S1106, the value of the variable k is compared with the number of icons arranged on the device map. If the value of the variable k is smaller than the number of icons, step S1107 follows (YES in step S1106). Otherwise, the processing routine is finished (NO in step S1106).
• In step S1107, information of the kth icon is checked, thereby discriminating whether this icon is the device icon and the network device associated to the device icon is the network device shown by the ID information stored in step S1102 or not. If YES, step S1109 follows (YES in step S1107). Otherwise, step S1108 follows (NO in step S1107).
• In step S1108, the kth icon is displayed in a normal format onto the device map. In step S1109, the kth icon is emphasis-displayed in a format such that it can be distinguished from other icons. In step S1110, “1” is added to the value of the variable k. In the case of displaying, a displaying position is determined on the basis of coordinate data included in the information of the icon and the icon is displayed in the position shown by the coordinate data.
• FIG. 11 shows a displaying process of the network device management software in the case where the network device management software is activated in each PC.
• However, in the case where the network device management software and the Web server are activated in the server PC and the Web browser activated in each client PC accesses the network device management software on the server PC, “display” inFIG. 11 denotes a process such that the network device management software on the server PC embeds the information to be displayed on the Web page which is provided to the Web browser via the Web server. That is, if the Web page has been described by a language such as HTML, XML, or the like, the information regarding the network device and the link to the device map are described in the Web page. Further, in step S1109, a message showing that the icon is emphasis-displayed is described in the Web page. The network device management software transmits data of the formed Web page to the Web browser via the Web server.
• By this method, when the image showing the outline of the installing locations is displayed on the device map, the icons showing the network devices can be displayed. Particularly, if thelink305 inFIG. 3 or thelink405 inFIG. 4 has been designated, the icons of the specific network devices can be emphasis-displayed. In which position in the device map the icon indicative of the network device designated by the user has been arranged can be displayed so that the user can easily confirm it.
• By a program which is installed from the outside, the network device management software according to the invention described above can be executed on thePC200 on which the network device management software shown inFIG. 2 can operate.
