Abstract

PURPOSE:To simplify the definition of the other party of a communication of each host computer by constituting the system so that the unitary management can be executed by the other party data terminal equipment number as a server. CONSTITUTION:In the on-line information processing system in which a host computer 100 connected to a data terminal equipment 200 being a server by a network 600 is connected to plural host computers 300, 400 through a WAN (wide area network) 500, when, target data terminal equipment information does not exist on the own host computer at the time of securing the connection, an inquiry is executed to the other party data terminal equipment, and the connection is secured, based on its data terminal equipment number. Since the unitary management can be executed, it is possible to cope simply with a change such as addition of the other party of a communication, etc.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention is utilized for network definition in online information processing. TECHNICAL FIELD The present invention relates to an online information processing system that allows network definitions to be easily performed in response to network changes.

0002

[Prior Art] Conventionally, in WAN (wide area network) connections, the network environment is defined by the correspondence between a logical address and a data terminal device number of the other party, and a connection can be established by making a call only to the defined host computer of the other party. there were.

0003

[Problems to be Solved by the Invention] In the conventional call control method described above, call settings cannot be made for any other host computer other than those defined for the own host computer, so every time a network change occurs, all host computers must be I needed to change the network definition.

[0004] The present invention solves such problems and aims to provide a system that can simplify the definition of information on a connected host computer.

[0005]

[Means for Solving the Problems] The present invention provides a method for connecting a plurality of host computers equipped with communication management means to a WAN (wide area network).
In an online information processing system, a data terminal device including a storage device is connected to each of the plurality of host computers via a network as a server, and each of the plurality of host computers is connected to the plurality of host computers as a server. A data terminal device information storage area is provided to store the numbers of the data terminal devices connected to the host computer, and each of the host computers does not know the data terminal device number of the other host computer, which is necessary to establish a connection using the other party's logical address. In such a case, the data terminal device is provided with an inquiry means for making an inquiry about the number, and when the data terminal device receives an inquiry from the inquiry means, searches the data terminal device information storage area using the logical address as a key, and searches the data terminal device information storage area for the corresponding data terminal device. comprising a response means for notifying the communication management means of the number;
The present invention is characterized in that it includes means for establishing a connection with a corresponding destination host computer based on the data terminal device number from the reply means.

[0006]

[Operation] When communicating with a destination host computer connected via a WAN (Wide Area Network), a data terminal device number corresponding to the logical address of the destination host computer is defined in the network environment definition of the own host computer. If it is not defined, an inquiry is made to the data terminal device of the other host computer, and a connection is established using the notified data terminal device number.

[0007] By centrally managing the data terminal device numbers and logical addresses of host computers connected via the WAN in this way, it is possible to easily deal with changes such as the addition of a communication partner. This simplifies the network definition for each host computer.

Embodiments Next, embodiments of the present invention will be explained based on the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The embodiment of the present invention includes a plurality of host computers 100, 300,
400 are connected to each other via a WAN (wide area network) 500, and a plurality of host computers 100, 300
, 400 each has a data terminal device 200 equipped with a storage device 230 that serves as a server for the network 600.
Further, as a feature of the present invention, a plurality of host computers 100 are connected to the storage device 230 via
, 300 , 400 , the data terminal device 20 connected to
Data terminal device information storage area 210 that stores the number 0
and host computers 100, 300, 4
00, each of which is equipped with an inquiry means 120 for inquiring about the data terminal device number of the other host computer when the number is unknown for establishing a connection using the other party's logical address, and the data terminal device 20
0, a response means 220 for searching the data terminal device information storage area 210 using the logical address as a key when receiving an inquiry from the inquiry means 120, and notifying the communication management means 110 of the corresponding data terminal device number;
The communication management means 110 includes means for establishing a connection with the corresponding partner host computer based on the data terminal device number from the answering means 220.

[0010] Although the network is connected to a WAN in this embodiment, it may be connected to a LAN.

Next, the operation of the embodiment of the present invention constructed as described above will be explained. FIG. 2 is a flowchart showing the flow of operation of the communication management means in the embodiment of the present invention, and FIG. 3 is a flowchart showing the flow of operation of the response means of the data terminal device in the embodiment of the invention.

The communication management means 110 performs a search process for searching whether or not a data terminal device number corresponding to a logical address is defined in the network environment definition of the host computer 100, and a search process for searching for a data terminal device number fails. a start process for activating the inquiry means 120 to make an inquiry to the data terminal device (server) 200 when the data terminal device (server) 200 is detected; and a call setting process for making a call to the data terminal device having the detected number and establishing a connection. I do.

[0013] The answering means 220 also performs a reception process of receiving an inquiry request from the host computer 100, a detection process of detecting a data terminal device number from the data terminal device information storage area 210 using a logical address as a key,
A transmission process for transmitting the detected data terminal device number is performed.
