Field of the Invention The present invention relates to a communication route setting system, and more particularly to a method for statically setting routing information to each relay device when setting a route between terminals communicating with each other via the relay device. And a method thereof.

[0002]

2. Description of the Related Art An L to which a terminal such as a computer is connected.
In a wide area network system in which a router connects an AN to each other or a LAN and a public network, a router located on a communication path receives data transmitted by a source terminal, and relays the data in sequence to thereby determine a destination. Deliver to the terminal. A router is a relay device that performs routing, but refers to routing information stored internally to which adjacent router the data received from a source terminal directly or via another router should be relayed. You can know by doing.

[0003] The routing information generally includes a destination network address, a network address of an adjacent router to which the received data is to be sent, and a metric indicating the number of routers to be passed to send the data to the destination network address. Have been. Each router is
By comparing the information specifying the transmission destination set in the received data with the routing information registered therein, the transmission destination of the received data is determined. Therefore, when performing communication between certain terminals, the routing information necessary for the communication between the terminals is set in advance in each terminal and each router located on the communication path for performing the communication between the terminals. Need to be kept.

[0004] As a method of setting routing information in a router, RIP (RIP) in the TCP / IP protocol is used.
outing Information Protocol
ol) and a method of statically setting the route manually. In the case of statically setting the routing information, if a network administrator or the like specifies a route between terminals, a router located on the route is transmitted to a local console connected to each router or a network management device. Must be set up in advance by remotely logging into the router via the network. At present, a network configuration representing information on the connection form of a network system based on the connection form information based on the connection form information of terminals connected to the network system, each relay device, and the network device including the LAN and the like. Since a map can be created and displayed, a network administrator or the like can visually grasp which router the routing information must be set by referring to the network configuration map.

[0005]

However, even if it is easy to specify which router the routing information has to be set by displaying the network configuration map, it is conventionally located on the route. Each router has to log in directly or remotely and set the routing information, which is troublesome.

The device management table 28 is a storage unit for registering information necessary for logging in and accessing the computer and the router, and stores the passwords of all the computers and the router in the WAN in the respective IDs.
Is stored in association with. FIG. 3 shows a setting example of the device management table 28. The model-specific management table 30 is a model-specific management storage unit for registering information necessary for setting routing information in a computer and a router, and includes the routing information check module and the routing information setting described above for each model.

In the present embodiment, the device management table 28, the model-specific management table 30, the model-specific routing information check module group storage unit 32, and the model-specific routing information setting module group storage unit 34 are stored on a magnetic disk.

The routing information setting unit 24 has two
It has two functions. One of them operates as a routing information setting unit, and automatically sets routing information in a computer and a router on a designated path by executing a predetermined setting module. The other operates as a routing information check means, and executes a predetermined check module before actually setting the routing information, thereby determining whether the computer and the router on the designated path need to set the routing information. Is determined. In addition, it also performs overall control in the present system which is not performed by the network management unit 18. The table management unit 26 manages updating of various information mounted on the device management table 28 and the model-specific management table 30 described above.

A feature of the present embodiment is that a route is designated on the network configuration map displayed by the above configuration, so that the routing information can be automatically set in the computer and the router on the route. That is. As a result, conventionally, it is necessary to log in to each router etc. and set each time.
In the present embodiment, the setting of the routing information can be performed simply by designating the route using the mouse 14 on the network configuration map without necessity.

Next, the operation of the present embodiment will be described with reference to the flowchart shown in FIG. Here, computer A connected to LAN 1 and LAN 6
A case will be described as a specific example in which a route is set between the computer B and the computer B.

First, in step 101, a route is specified on the network configuration map. FIG.
FIG. 3 is a diagram illustrating a display example of a network configuration map displayed on a display unit 12. In the present embodiment, the network configuration map is divided into three submaps and displayed. According to the example shown in FIG. 6, the uppermost area is an area for displaying a submap of the network configuration of the entire WAN, and the lower two areas represent the connection form of the LAN to which the terminating computer is connected. This is an area for displaying a submap. At first, the end computer has not been specified yet, so the LA
Nothing is displayed on the N submap. In the submap of the entire WAN, the connection relationship between the LAN and the public network and the router connecting them is indicated by symbols as shown in FIG.

A network administrator specifies a LAN to which a terminal computer to which a route is to be set is connected on a submap of the entire WAN. The designation on the map is performed by clicking with the mouse 14. The network administrator knows in advance the correspondence between the actual WAN configuration and the submap of the entire WAN displayed on the display unit 12, and the terminal computer
It is possible to determine which subnetwork on the submap of the entire AN is connected. In this example,
Since LAN1 and LAN6 are selected, the connection form of each of LAN1 and LAN6 is displayed in the area of the submap of each LAN. Then, the terminal computers A and B are selected in the submap of each LAN.

Incidentally, there are a plurality of routes that can be set between the computer A and the computer B. Therefore, when the network administrator determines which of the routes is to be selected, the network administrator specifies the network and the router located on the selected route by clicking. In this example, routers R10, R20, R30, R4
It is assumed that the path formed by 0 is selected. The designated route can be visually confirmed by highlighting the designated computer, LAN or public network and router.

In step 102, when the route is determined as described above, the network management unit 18 determines the information on the computers and routers located on the route, at least the ID and type of each device, and the connection relationship between them. The information is extracted from the device information database 16 and passed to the routing information setting unit 24.

In step 103, the routing information setting unit 24 collects and generates routing information to be set in the computer and each router. More precisely, at this point, a list of data necessary for setting the routing information is collected. For example, the routing information set in the router R10 is such that if the communication data from the computer A received via the LAN 1 is data to the computer B, it is sent to the router R20. Also,
Conversely, if the communication data from the computer B received via the router R20 is data for the computer A, the content is to be sent to the computer A. Similarly, the routing information to be set in the router R20 is such that if the communication data received from the router R10 is data to the computer B, it is sent to the router R30, and conversely, the communication data received from the router R30 is If the data is for A, it is sent to router R10. Thus, bidirectional routing is considered. The routing information is generated for each device based on information on the computer and the router on the designated route and the connection information of each device.

Next, in step 104, the routing information setting unit 24 collects a list of routing information already set from the computers A and B located on the route and the routers R10 to R40. This can be collected by executing a predetermined check module specified for each type of network device. That is, based on the types of the computer and the router sent from the network management unit 18, the name of the routing information check module is acquired from the type-specific management table 30, and the actual module corresponding to the name is classified into the type-specific routing information check module group. By taking out and executing from the storage unit 32, it is possible to collect for each network device. The routing information setting unit 2
4 is a device management table 2 based on the computer and router IDs sent from the network management unit 18.
8, the password of each device can be obtained, so that it is possible to remotely log in and collect the set routing information.

In step 105, the routing information setting unit 24 compares the list of routing information created in step 103 with the list of set routing information collected from each router or the like in step 104 for each router or the like. It is determined whether the setting of the routing information is necessary. For example, if the same routing information as the content to be set is already set in a certain router, there is no need to set again. Therefore, the routing information setting unit 24
If the contents of the routing information to be set have already been set, the process ends without setting the routing information described later. This process is performed for all the computers A and B and the routers R10 to R40 on the route.

If it is determined in step 105 that the setting of the routing information is necessary, the routing information setting unit 24 sets the routing information in the computer and the router located on the route in step 106. This can be set by executing a predetermined setting module specified for each type of network device. That is, based on the types of the computer and the router sent from the network management unit 18, the routing information setting module name is acquired from the model-specific management table 30, and the actual module corresponding to the name is classified into the model-specific routing information setting module group. The setting can be performed for each network device by taking out from the storage unit 34 and executing it. The model-specific routing information setting module to be executed can automatically set the routing information for each network device by using the created list of routing information as a parameter list. Note that the password required for the setting has already been obtained by the above-described check processing.

In this way, when the necessary routing information is set for each of the computers A and B at the ends on the route and the routers R10 to R40 on the route located between the computers, the routing information setting unit 24 becomes Is displayed as a setting result (step 10).
7).

As described above, according to the present embodiment, the routing information can be automatically set in the computer or the router located on the route only by designating the route on the network configuration map with the mouse 14. Therefore, it is simple and does not cause a setting error due to an input error or the like for each network device. In addition, since a check mechanism for setting necessity is provided before setting is actually performed, it is efficient.

As described above, in the present embodiment, the necessity of setting the routing information on the routers on the route is checked in advance by comparing the routing information. In addition, it is also possible to check whether or not setting is possible, for example, whether there is a resource capacity, limitation or security problem.

In the process of specifying a route, if there is only one route that can be selected, the route is automatically highlighted on the map. A function may be added such that an appropriate route is obtained by automatic calculation based on the source or the like, and an inverted value is automatically displayed on a map as an initial value.

In the above description, the terminal is specified as both ends of the route. Alternatively, a LAN may be specified. In this case, the routing information is automatically set collectively for all the terminals connected to the LAN. This is because the LAN ID and connection information are stored in the device information database 16,
It can be easily realized only by creating a setting module.

Further, in the present embodiment, a conventional network management device is used, but it goes without saying that the present invention can be implemented even if it is separately provided.

[0035]

According to the present invention, the routing information can be automatically set to the terminal and the relay device on the route only by designating the route on the displayed network configuration map by the instruction means. The setting of the routing information can be easily performed without having to remotely log in to each relay device or the like. Further, since the setting of the routing information is performed by executing the setting module, a setting error due to an input does not occur, and the setting can be performed accurately and reliably.

A setting module for setting routing information having the same contents is provided in a form corresponding to each model, and a model-specific management means is provided to provide a setting module according to the model of each relay device. Since the module can be executed, it is possible to set the routing information even when different models are mixed on the route to be set.

In addition, since it is determined in advance whether the setting of the routing information is necessary or not, and the setting of the routing information is not performed when the setting has already been made, it is efficient.

Further, a check module for performing the same check processing is provided in a form corresponding to each model, and a model-specific management means is provided to execute the check module according to the model of each relay device. Since it is made possible, even if different models are mixed on a route to be set, it is possible to reliably collect the already set routing information.
