  However, the technique described in Patent Document 1 supports LSP (Label Switched Path) editing of MPLS (Multi-Protocol Label Switching) on a display screen, and a path (GMPLS) between routers by light in a physical layer. (Generalized Multi-Protocol Label Switching) LSP) is not considered to facilitate editing.

  For example, as shown in FIG. 1, in the prior art, a multi-layer network can be regarded as being divided into an IP layer and a physical layer. In the case of a network composed of routers, optical cross-connects, and optical fibers, the IP layer screen displays IP processing routers (routers A, B, and C) and IP links indicating the connection relationship between the routers. Is done. On the other hand, on the screen of the physical layer, the OXC constituting the network and the GMPLS optical path passing between the OXCs are displayed. However, the components on the screen of these layers are related to each other, and the routers A, B, and C displayed on the screen of the IP layer and the routers A, B, and C displayed on the screen of the physical layer. Are the same devices. In addition, the IP link of the IP layer displays the connection relationship between the start and end routers of the optical path passing through the OXC of the physical layer (see FIG. 2). Here, since the screen of each layer only displays the same network, information that should be consistent with the information of each layer (router name, relative position information on the screen display, Relationship between the IP link and the optical path).

<Overview>
DESCRIPTION OF EMBODIMENTS Embodiments (embodiments) for carrying out the present invention will be described. In the following description, it is assumed that the network includes a router, an OXC (optical cross-connect), and an optical fiber connecting these, and can use GMPLS (Generalized Multi-Protocol Label Switching). First, an overview of screen display processing by the network information management apparatus 10 (described later) of the present embodiment will be described with reference to FIGS.

  The network information management apparatus 10 in FIG. 3 displays each component of the network (router 60, OXC 70, IP link, optical path, optical fiber, etc.) on the display screen for each layer. For example, as shown in FIG. 5, the IP layer components are displayed on an IP layer display panel (display screen) 501, and the physical layer components are displayed on a physical layer display panel (display screen) 502.

  Here, the network information management apparatus 10 creates IP layer drawing data and physical layer drawing data as drawing data of the display screen of each layer as shown in FIG. Here, the network information management apparatus 10 refers to the same data source 131 (information on the components of each layer of the network) when creating the drawing data of the display screen of each layer. That is, information that has conventionally been individually provided for each layer is collectively managed. This data source 131 includes router, OXC, optical fiber, IP link, optical path GUI data, device operation status data, control internal data (for example, which optical path each IP link is configured by, This information indicates which router, which OXC each optical path passes through, and the like.

  The network information management apparatus 10 refers to router information (router information) and IP link information (IP link information) in the data source 131 when creating the IP layer drawing data. Further, the network information management apparatus 10 creates the physical layer drawing data, among the data source 131, the router information, the OXC information (OXC information), the optical fiber information (optical fiber information), and the optical path. Information (optical path information). By doing in this way, the network information management apparatus 10 can display the network information of each layer without contradiction on the display screen of each layer. When the change of the setting content is received from the display screen of any layer, the network information management apparatus 10 reflects this change content on the data source 131. Further, the information of the data source 131 that needs to be changed in relation to the change contents is also changed. Therefore, the network information management apparatus 10 can reflect the setting change received from the display screen of any layer in the information of other layers.

  Next, a configuration example of a system including the network information management apparatus 10 will be described with reference to FIG. The system includes a network information management device 10, a network control device 20, and a network 30. As described above, the network 30 includes the router 60, the OXC 70, and the optical fiber, and is a network that can use GMPLS. The network control device 20 monitors the status of the router 60, the OXC 70, and the like of the network 30, and collects the operating status data of each device. Then, an identifier is assigned to each component of the network 30 and transmitted to the network information management apparatus 10 together with the collected operation status data. In addition, the network control device 20 receives the optical path setting information input from the network information management device 10 via the input unit 40, and transmits control commands for the router 60 and the OXC 70 in order to realize the optical path setting. The router 60 and the OXC 70 of the network 30 are controlled.

  The network information management apparatus 10 is realized by a computer including an input / output interface, a communication interface, a CPU (Central Processing Unit), a RAM (Read Only Memory), an HDD (Hard Disk Drive), and the like.

  In the following description, the user interface unit 11 is realized by an input / output interface and a program execution process by the CPU. The data source management unit 12 and the request control unit 14 are realized by a program execution process by the CPU. The communication unit 15 is realized by a communication interface that can communicate with the network control device 20. Furthermore, the storage unit 13 includes a storage medium such as a RAM, a ROM (Read Only Memory), an HDD, and a flash memory. The network control device 20 is a separate device from the network information management device 10, but the network control device 20 may be incorporated in the network information management device 10.

  The network information management apparatus 10 displays network information by layer. Further, it receives an instruction input from the operator via the input unit 40 and transmits an optical path setting command to the network control device 20. The network information management apparatus 10 may constantly monitor the operating status of the network, and display a screen prompting the operator to change the optical path setting on the output unit 50 when the operating status changes. .

  Details of the configuration of the network information management apparatus 10 will be described. The input unit 40 is means for inputting various information received from the user, such as a keyboard and a mouse, to the network information management apparatus 10. The output unit 50 is means for outputting information handled by the network information management apparatus 10 such as a monitor or a printer.

  The user interface unit 11 displays a screen composed of icons and a plurality of panels in order to make it possible to intuitively set network components and their settings. Such a user interface unit 11 displays a display screen of each layer on the screen of the input receiving unit 111 that receives a display instruction on the screen or input of various setting information via the input unit 40 and the output unit 50. A display processing unit 112.

  The data source management unit 12 creates the drawing data 132 of the display screen of each layer based on the data source 131 stored in the storage unit 13. When an input of a change instruction for the data source 131 is received, the contents of the data source 131 are changed.

  The storage unit 13 stores a data source 131 and includes an area for storing drawing data 132 and editing data 133. The drawing data 132 and the editing data 133 are created on, for example, a RAM provided in the storage unit 13.

  The data source 131 is information related to the components of the network, and is data that is referred to for creating drawing data 132 (IP layer drawing data and physical layer drawing data). A configuration example of the data source 131 is shown in FIG.

  As shown in FIG. 4, the data source 131 includes router information, OXC information, IP link information, optical path information, optical fiber information, and the like. Among these, router information and IP link information are used for creating IP layer drawing data. Router information, OXC information, optical fiber information, and optical path information are used for creating physical layer drawing data.

  Each information of the data source 131 is constituted by information of three attributes of GUI data, device operation status data, and control internal data. The GUI data is data for screen display such as the display position on the screen, and the device operation status data is data indicating the operation status of the device (or link or optical path). The internal control data is data used to control the device (or link or optical path).

  For example, the router information includes information on a router name and a relative display position on the screen as GUI data. In addition, information on the CPU usage rate is provided as the device operation status data, and information such as a router identifier is provided as the control internal data. Furthermore, OXC information and optical fiber information are also used as GUI data, such as OXC and optical fiber names, relative display positions on the screen, device operating status data, the number of OXC free ports, and OXC as control internal data. And information such as an optical fiber identifier.

  The IP link information includes information such as a name and display color as GUI data, and includes up / down information of the IP link as device operation status data. Further, the control internal data includes an identifier of an IP link, an identifier of one or more optical paths constituting the IP link of itself, and an identifier of a start router and an end router of the IP link. Here, the IP link information holds one or more optical path identifiers as control internal data because the IP link is composed of one or more optical paths. Thereby, the relationship between the IP link and the optical path is maintained.

  The optical path information includes information such as a name and display color as GUI data, and includes, as control internal data, optical path identifiers, optical path start and end router identifiers, start and end routers OXC list (list of OXC identifiers) passed between and an IP link identifier to which its own optical path belongs. Further, the optical fiber information includes a name and relative display position on the screen as GUI data, and an optical fiber identifier (fiber identifier) as control internal data.

  The drawing data 132 is composed of IP layer drawing data and physical layer drawing data. The IP layer drawing data is displayed on the screen, for example, like the IP layer display panel 501 in FIG. 5, and the physical layer drawing data is, for example, physical The screen is displayed like a layer display panel 502. With this screen display, it is easy for the operator to intuitively understand which optical path the IP link in the IP layer is composed of in the physical layer and which OXC or optical fiber the IP link passes through. Become. The editing data 133 is editing data of the drawing data 132 and the data source 131.

  When the request control unit 14 in FIG. 3 receives an instruction input for optical path setting via the user interface unit 11, the request control unit 14 converts the instruction input into a protocol that can be processed by the network control device 20, and passes through the communication unit 15. Send with. Further, the request control unit 14 converts the information transmitted from the network control device 20 into information that can be processed by the data source management unit 12. The communication unit 15 communicates various information with the network control device 20.

<Initial screen creation procedure>
Next, the processing procedure of the network information management apparatus 10 will be described. First, a procedure for creating an initial screen (initial display screen) will be described with reference to FIG.

  In order to grasp the current state of the network 30, the request control unit 14 of the network information management apparatus 10 receives from the network control apparatus 20 the arrangement of routers and OXCs, connection relations using optical fibers, path setting status of optical paths, and other necessary In response to the request, information on the operating status is requested (S1). The trigger for the information request here may be when the network information management apparatus 10 is activated or when the operator explicitly inputs an instruction via the input unit 40.

  The request control unit 14 converts various information collected from the network control device 20 into a form that can be processed by the data source management unit 12. Then, the collected various information is stored in the data source 131 via the data source management unit 12 (S2).

  Subsequently, the data source management unit 12 generates IP layer drawing data from the router information and IP link information of the data source 131, and generates physical layer drawing data from the router information, OXC information, optical path information, and optical fiber information. Generate (S3).

  The display processing unit 112 of the user interface unit 11 displays the IP layer drawing data on the IP layer display panel 501 and the physical layer drawing data on the physical layer display panel 502 (S4).

<Edit router name and display position>
By the initial screen creation process as described above, for example, a screen as shown in FIG. 7 is displayed on the output unit 50 of the network information management apparatus 10. Here, the name of the router displayed on both the IP layer display panel 501 and the physical layer display panel 502 and the relative position on the display screen can be edited from either panel. However, it is a change to the same router (router object) when operated from either panel. Therefore, the change received from one display panel needs to be reflected on the other display panel.

  Here, when an instruction input for editing the router name and the display position is received from any of the display panels via the input reception unit 111, the data source management unit 12 transmits the instruction input in the router information of the data source 131. Reflect and update the router name and display position. Then, the display processing unit 112 displays the display panel of each layer based on the updated router information.

  For example, as shown in FIG. 7, when the name of the router 60A of the IP layer display panel 501 is changed from “router A” to “router D” and the display position is moved, the input contents from the IP layer display panel 501 Accordingly, the physical layer display panel 502 reflects the movement of the display position of the router 60A and the name change. The reflection timing may be immediate, may be a method of updating the contents of both display panels every predetermined time, or may be when the operator instructs.

<Optical path and IP link settings>
The optical path setting can also be accepted from either the IP layer display panel 501 or the physical layer display panel 502. For example, when the input reception unit 111 receives the setting of the optical path from the physical layer display panel 502, the input reception unit 111 sequentially receives the selection input to the destination router in order of the OXC routed from the optical path or the IP link start router. At this time, the data source management unit 12 generates optical path information storing the identifier of the optical path, the identifier of the selected start router, the identifier of the end router, and the transit OXC list. When the optical path information is generated, the data source management unit 12 copies the selected start router identifier and end router identifier from the optical path information to generate IP link IP link information. The optical path identifier of the IP link information stores the identifier of the optical path that realizes the IP link. In addition, when there is IP link information of the same IP link for the optical path to be generated and the start point router and the end point router (that is, when an optical path to be newly set adds an optical path to an existing IP link), An optical path identifier copied from the optical path information is added to the IP link information.

  On the other hand, when the input receiving unit 111 sets from the IP layer display panel 501, the input receiving unit 111 receives selection input of a start point router and an end point router (start / end point router). At this time, first, the data source management unit 12 generates optical path information storing the identifiers of the start and end routers. Here, for OXC passing between the start router and the end router, the display processing unit 112 may display a screen prompting the user to make a selection input, and the OXC input from the screen may be used. The source management unit 12 may obtain a predetermined algorithm such as a Dijkstra algorithm based on the OXC information. Then, the data source management unit 12 stores the input OXC identifier obtained by the OXC or Dijkstra algorithm or the like in the optical path information. Thereafter, IP link information is generated, and the identifier of the start router, the identifier of the end router, and the optical path identifier copied from the optical path information are stored.

  Then, based on the optical path information and the IP link information created in this way, the data source management unit 12 creates the drawing data 132 of the IP layer display panel 501 and the physical layer display panel 502, and the display processing unit 112 The IP layer display panel 501 and the physical layer display panel 502 are displayed. In any case, when the optical path cannot be established due to a shortage of data source equipment, the data source management unit 12 instructs the display processing unit 112 to display an error display screen.

  By performing the processing as described above, the network information management apparatus 10 can consistently set the optical path and IP link setting information input from either the IP layer display panel 501 or the physical layer display panel 502 without any contradiction. Can be reflected in each of the optical path information and the IP link information. Therefore, the optical path and the IP link can be set from the display panel of any layer. Further, the network information can be displayed on the IP layer display panel 501 and the physical layer display panel 502 without contradiction.

<About deletion of optical path and IP link>
In addition, deletion of an optical path or an IP link can be accepted from either the IP layer display panel 501 or the physical layer display panel 502. For example, when the input reception unit 111 receives the deletion of the optical path from the physical layer display panel 502, the data source management unit 12 first searches the data source 131 for the optical path information of the optical path to be deleted. Then, referring to the identifier of the IP link indicated in the searched optical path information and the identifier of the optical path in the IP link information of the IP link of the identifier, the IP link is configured only with the optical path to be deleted. Judge whether or not. Here, when it is determined that the IP link is configured only by the optical path to be deleted, the data source management unit 12 deletes the optical path information and the corresponding IP link information. On the other hand, when it is determined that the IP link includes other than the optical path to be deleted, the optical path information is deleted and the identifier of the optical path to be deleted is deleted from the corresponding IP link information.

  When the input reception unit 111 receives deletion of an IP link from the IP layer display panel, the data source management unit 12 searches the data source 131 for IP link information to be deleted. Then, all the optical path information having the identifier included in the searched IP link information is deleted together with the corresponding IP link information. In this way, the display processing unit 112 can delete the optical path and the IP link from the display panel of any layer. Further, the network information can be displayed on the IP layer display panel 501 and the physical layer display panel 502 without contradiction.

  The display screen displayed by the display processing unit 112 may include a panel other than the physical layer display panel 502 and the IP layer display panel 501. Further, the IP layer display panel 501 and the physical layer display panel 502 may display more information than the information illustrated in FIG. 5 as necessary. For example, the physical layer display panel 502 may display the disconnection status of the installed optical fiber, and the IP layer display panel 501 may display a screen for accepting LSP editing by MPLS and the traffic volume.

  The optical path information may include information on the bandwidth (capacity) of the optical path, and the IP link information may include information on the total value (total capacity) of the bandwidths of the optical paths constituting the IP link. . In this case, the data source management unit 12 increases or decreases the value of the capacity of the IP link information as the optical path constituting the IP link increases or is deleted. Here, the value of the capacity to be increased or decreased is based on the capacity of the optical path indicated in the optical path information of the optical path to be increased or deleted.

  Further, the optical path may be configured with one optical fiber as a unit, or may be configured with one type of wavelength inside the optical fiber as a unit. When an optical path is configured in units of wavelengths as described above, wavelength information is prepared instead of optical fiber information, and information on each optical path includes an identifier of a wavelength used by the optical path.
