Abstract

PURPOSE:To prevent a trouble due to the contradiction of network information among respective communication nodes by automatically obtaining the newest network information for constructing a network system through the use of a chance to reset a data link by means of respective communication nodes. CONSTITUTION:In a communication node 100, a link information notice means 14 gives the notice of the chance that the data link has been reset to a network information control means 13. At that time, the network information control means 13 obtains and transfers network information of an adjacent communication node 300 by using an information access control means 12 and an adjacent station communication means 11. Consequently, network information required is automatically set in a network information save area 30, and the network system of the newest information can automatically be constructed. Thus, the trouble due to the contradiction of network information can be prevented.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to information construction of an entire network in one node of a network system constructed by a plurality of communication nodes or information processing devices such as packet switching in the field of communication networks. Regarding the method.

[Conventional technology]

Conventionally, in this type of network construction method, information on adjacent communication nodes or information processing devices is set during initial processing of a communication node or information processing device, and cannot be changed during operation.

[Problem to be solved by the invention]

In the conventional network construction method described above, information on adjacent communication nodes, node information, or information processing equipment must be set in advance at the initial stage, so complex network information must be prepared manually in advance. It has the disadvantage that it cannot be used.

Another disadvantage is that when the configuration information of one communication node or information processing device is changed, the configuration information of other adjacent communication nodes or information processing devices needs to be changed, so initial processing is required again. There is.

[Means to solve the problem]

According to the present invention, in a method for constructing network information between communication nodes in a network system configured by an information processing device including a plurality of communication nodes, from a data link control unit that controls a line between communication nodes,
a link information notification means for notifying data link setting information; an adjacent station communication means for communicating with an adjacent communication node;
It has information access control means for accessing information of the other communication node using the adjacent communication means, and network information management means for acquiring information of other communication nodes and managing it as all network information. The link information communication means notifies the network information management means of an event such as the establishment of a data link of By performing acquisition and transfer, an automatic network construction method is obtained in which the network system automatically sets necessary network information in a save area.

〔Example〕

Next, the present invention will be described in more detail with reference to the drawings showing one embodiment of the present invention.

Referring to FIG. 1, a network system according to an embodiment of the present invention includes a plurality of communication nodes 100, 200, 300 such as packet switches and terminal devices 150, 250.
, 350. In this network system, network information between communicating nodes is stored in network information save areas within network programs 110, 210, and 310.

When a change in the configuration of the terminal device of one communication node 300 in the network system occurs, the communication node 3
The system configuration of 00 will be changed and reinitialization processing will be performed. At this time, the data link control unit 20 of the other communication nodes 100 and 200 detects the resetting of the data link.

In the communication hoop 100, the link information notification means 14 notifies the network information management means 13 of the opportunity for resetting the data link. At this time, the network information management means 13 controls the information access control means 12.
and the adjacent communication node 3 using the adjacent station communication means 11.
By acquiring and transferring 00 network information, you can automatically obtain the necessary network information.
By setting it in the network information save area 30, the latest information network system can be automatically constructed.

Also in communication node 300 and communication node 200,
By performing similar processing, it is possible to automatically construct a network using the latest information.

〔Effect of the invention〕

As explained above, according to the present invention, each communication node can automatically acquire the latest network information for constructing a network system by using the opportunity of resetting a data link. According to
Troubles due to inconsistencies in network information between communication nodes can be prevented.

Furthermore, since each communication node accesses the network information of the other communication node by itself, mistakes that tend to occur when manually setting network information can be prevented.
