Abstract

PURPOSE:To make the input of configuration setting information on rooters constituting the network efficient and reduce misinput by concentrically inputting the configuration setting information. CONSTITUTION:When the network is structured, the configuration setting information on the respective rooters 1 is concentrically inputted to the network storage part 23 of a host terminal 2. When a request packet 101 is sent out of a rooter 1a nearby the host terminal 2 first, the host terminal 2 receives it, reads configuration setting information on a transmission source address out of the network storage part 23, and composes and sends a response packet 102 out. The rooter 1a receives the packet and automatically inputs it to a configuration storage part 13. Then a request packet 101 is sent out of a rooter 1b and input operation is similarly performed, but the rooter 1a performs address conversion at this time by using the inputted configuration setting information and repeats packets.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network configuration setting information input method, and more particularly to a configuration setting information input method required for line setting for a router constituting a network.

[0002]

2. Description of the Related Art Conventionally, various types of networks have been found in this type of network. For example, in the same factory or the same office for company communication, a plurality of LANs each including a floor are used as routers. Connect to each other to form a network. In addition, this type of network in another area, WAN, or leased line public line,
There are various types such as connecting a communication system using ISDN or the like with a router or the like to configure a network for expanding in a wide area.

A router is an OSI (Open System).
LA in the third layer network layer in the layer of communication means defined as em Interconnection).
Other than this, there are bridges that connect at the second layer and gateways that connect at the fourth layer and above. The selection of these connecting means is more effective and lower in cost depending on the protocol of the LAN to be connected, the scale of the network, the communication form and the like.

A large number of terminal devices are connected to each transmission line of these networks, and communication is performed between these terminal devices by a packet method. Furthermore, the terminal devices are centralized to perform maintenance management of the entire network. One host terminal is provided.

FIG. 1 is a block diagram showing an example of this type of network. This figure shows a simple example of a corporate network for the sake of clarity.

In the router 3, configuration setting information including address information of each protocol for each router, filtering information for limiting the communication range of the network, routing information indicating route information between routers, etc. is input and stored in advance. . That is, the configuration setting information is used for the line setting based on the address of the packet transmitted from the terminal device 3, or the judgment of discarding the packet having no destination.

[0007] Further, the operation of inputting the configuration setting information is performed by an administrator who has some knowledge of the network at the time of constructing the network, for each router.
I am inputting one by one.

[0008]

As described above, in the conventional example, since the person having the knowledge of the network inputs the configuration setting information for each router, the network becomes particularly large-scaled. Many people who have knowledge of networks are required, and much labor is required. There is also a problem that an input error may occur due to manual work.

In a configuration setting information input method of previously inputting setting information to each of the routers, a means for collectively inputting the configuration setting information of each of the routers to the host terminal at the time of starting the network, and the host terminal, A means for sequentially accessing the host terminal via the network to the routers further away from the router connected to the connected LAN, reading the configuration setting information of the host terminal, and inputting the configuration setting information to the storage unit of the host terminal. There is.

As a communication means for accessing the host terminal, each of the routers sends out a request packet requesting the configuration setting information, and the host terminal receives the request packet and receives the request packet from the requesting router. A method of sending the configuration setting information in a read response packet may be used.

[0011]

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of an example of a network which is a target of this embodiment. FIG. 2 is a block diagram showing the internal configurations of the router and the host terminal according to this embodiment in FIG.

In FIG. 2, the host terminal 2 comprises an interface section 21, a configuration control section 22, and a network storage section 23. Detailed network configuration information of the entire network including configuration setting information and the like is registered in the network storage unit 23 in advance. The router 1 includes an interface unit 11, a configuration control unit 12, and a configuration storage unit 13. In the configuration storage unit 13, the configuration setting information of the host terminal 2 to be input, the network address of the host terminal 2, the router name of the host terminal 2, and the like are registered.

Next, the operation of each section until the configuration setting information is input to each router 1 will be described. In the state where the network is constructed and the configuration setting information of each router is input to the host terminal 2, a request packet requesting the configuration setting information is first sent from the router 1a close to the host terminal 2 in order to start it. It This request packet 101 is shown in FIG.
In the format shown in (a), the destination address of the data link part is the broadcast address, the source address is the router address, the request flag of the network part is 1, the response flag is 0, the destination address is the host address, the source address. Is blank, and the data is the router name.

The host terminal 2 receives this request packet 101, and by checking the request flag and the destination address of the network section, recognizes that it is the request packet 101 for its own host terminal 2 and receives it. The host terminal 2 checks the router name of the network part,
The configuration setting information regarding the router 1a registered in the network storage unit 11 is taken out. This is sent in the response packet 102. This response packet 102 has the format shown in FIG. 3B, in which the destination address of the data link section is the broadcast address, the source address is the host address, the request flag of the network section is 0, the response flag is 1, and the destination The address is the router address, the source address is the host address, and the data is the configuration setting information and the router name.

The router 1a receives the response packet 102 and checks the response flag and the router name,
Recognize that it is a response packet for itself and receive it.
Then, this is input to the configuration storage unit 13.

The interface unit 11 performs transmission / reception of packets such as requests and responses and format conversion,
The configuration control unit 12 controls packet input / output to / from the interface unit 11 and the configuration storage unit 13.

When the input work of the router 1a is completed, the request packet 101 is next sent from the router 1b and the input work is performed similarly. At this time, the request packet 10 from the router 1b is sent.
1 or the response packet 102 from the host terminal 2 is
The router 1a passes through as a relay router. The router 1a receives these relay packets, checks the address of the transfer destination from the configuration setting information of the configuration storage unit 13 registered in advance, changes the destination address of the data link unit to this address, and transmits the packet. Forward. Although only the routers 1a and 1b are shown in FIG. 2, the other routers shown in FIG. 1 also sequentially perform the input work in this manner.

Also, when the network is expanded and a new router is added, the configuration setting information of the additional router is first input to the network storage unit 23 of the host terminal 2, and the additional router is connected via the network. It accesses this to read and input its own configuration setting information.

[0020]

As described above, according to the present invention, the configuration setting information of each router is centrally input to the host terminal, and each router accesses the host terminal via the network and automatically outputs its own configuration setting information. Since the data is input in the same manner, there is an effect that the input work can be made more efficient and setting mistakes are reduced. In particular, when the network becomes large-scale, or when the router is added or the setting information is updated, the centralized management has a great effect.
