Abstract

PURPOSE:To control network topology by using an easily usable name having meaning or the like by using a logical network topology corresponding to a physical network topology. CONSTITUTION:A mapping information data base 4 has mapping information to map the logical network topology provided in a logical network information data base 3 to the physical network topology provided in a physical network information data base 2. According to instruction information inputted from an input/output device 1 by a network user, a logical information construction processing 5 constructs logical information to control the logical network topology of the logical network information data base 3. According to the mapping information provided in the mapping information data base 4, a mapping conversion processing 6 converts the logical information constructed by the logical information construction processing 5 to physical information for controlling the physical network topology of the physical network information data base 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a network topology management system, and more particularly to a network topology management system in which a network operator manages the network topology by giving instructions to the network.

[Conventional technology]

In the conventional network topology management method, a network operator manages the physical network topology by providing physical network information to the network according to the actual physical network topology.

[Problem to be solved by the invention]

In the conventional network topology management method described above, the network operator provides and manages the physical network information for the network according to the actual physical network topology. It has the disadvantage that it is not possible to freely define and use meaningful names that are easy to take and use, but it is necessary to memorize and use predetermined symbols and numbers.

The purpose of the present invention is to use a virtual logical network topology that corresponds to an actual physical network topology, thereby using freely defined logical network information such as meaningful names that are easy for network operators to use. The object of the present invention is to provide a network topology management method that can manage network topology.

[Means to solve the problem]

The network topology management method of the present invention has (A) an input/output device that outputs network information to a network operator and inputs instruction information from the network operator, and (B) physical network information that indicates the actual physical network topology. a physical network information database; (C) a logical network information database having logical network information indicating a virtual logical network topology; (D) a physical network topology having the logical network topology contained in the logical network information database in the physical network information database. (E) a logical information construction process that constructs logical information for managing the logical network topology of the logical network information database based on instruction information input by a network operator from the input/output device; (F) a mapping conversion process that converts the logical information constructed in the logical information construction process into physical information that manages the physical network topology of the physical network information database using mapping information included in the mapping information database. It is configured.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the network topology management method of the present invention.

As shown in FIG. 1, the input/output device 1 can output network information to a network operator and input instruction information from the network operator.

Further, the physical network information database 2 has physical network information indicating the actual physical network topology.

On the other hand, the logical network information database 3 has logical network information indicating a virtual logical network topology.

Further, the mapping information database 4 has mapping information for mapping the logical network topology in the logical network information database 3 to the physical network topology in the physical network information database 2.

Therefore, the logical information construction process 5 constructs logical information for managing the logical network topology of the logical network information database 3 based on the instruction information input by the network operator from the input/output device 1.

Then, the mapping conversion process 6 includes the logical information construction process 5.
The logical information constructed by Mapping Information Database 4
The mapping information contained in the physical network information database 2 is converted into physical information for managing the physical network topology of the physical network information database 2.

FIG. 2 is an information configuration diagram showing an example of physical network information and logical network information of this embodiment.

As shown in FIG. 2, the physical network information 21 is physical configuration information that is centrally managed using component types and their physical numbers.

On the other hand, the logical network information 22 indicates one piece of logical configuration information that is managed in a multidimensional manner.

Therefore, the physical network information database 2 has physical information records 23 corresponding to the physical network information 21.
The logical network information database 3 has the following:
Logical information records 24 and the like corresponding to the logical network information 22 are developed, and the mapping information database 4 has mapping information records 25 and the like.

〔Effect of the invention〕

As explained above, the network topology management method of the present invention uses a virtual logical network topology that corresponds to the actual physical network topology, allowing network operators to freely use meaningful names that are easy to use. This has the advantage that the network topology can be managed using the logical network information defined in the above.
