Abstract

PURPOSE:To allow the system to cope flexibly with the revision in the network configuration by providing a device always storing various sets of information in the network. CONSTITUTION:Suppose that work stations WS1, WS3 and WS4 are in operation, The WS1 collects network information with the WS3, WS4 and writes the information in an area able to be referenced. That is, each work station collects sequentially communication information and resource information or the like stored in other work stations and stores the information in an area of its own. The information is written in other area of its own at a prescribed interval and references the latter area at communication. Thus, the system copes flexibly with the revision of the network configuration.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for acquiring and retaining communication-related information and resource information in a workstation network.

[Conventional technology]

Conventionally, in a workstation network, a common method for communicating with a communication partner with which each workstation can communicate is to register the information necessary for communication in a characteristic area in advance, and then communicate by referring to that area. Alternatively, there is a method in which the information is held by a server that manages the entire network. Related methods of this type include JP-A-63-284943 and JP-A-63-24.
No. 5039 etc. are mentioned.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not give consideration to ensuring the latest information regarding workstations, resources, etc. in the network, and there is a problem in that when the information changes, it is difficult to respond quickly.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to flexibly respond to changes in network configuration and to quickly utilize resources within the network.

[Means to solve the problem]

In order to achieve the above object, each workstation receives communication information held by other workstations.
It sequentially collects resource information and stores it in its own area. This is written in another area of the device at regular intervals, and the latter area is referred to during communication.

[Effect]

The present invention uses a mechanism that retains not only information necessary for communication but also information regarding devices connected to each workstation, thereby recognizing communication partners with which communication is possible and accurately grasping the existence of available devices.

〔Example〕

FIG. 1 is a block diagram showing a network in one embodiment of the present invention.

In FIG. 1, WSI, WS3. Assume that WS4 is running. In WSI, network information of WS3 and WS4 is collected and written to a referenceable area. Figure 2 is an example of a network information storage area.
Figure (a) is retained in WSI. WSI is W
When communicating with S3, the host name and host address are recognized from FIG. 2(a). In addition, if WSI requires a magnetic tape device, please refer to Figure 2 (a).
Recognizing that a magnetic tape device is connected to 4, the WS
Achieve the objective via step 4.

Next, when WS4 is powered off and WS5 starts operating, from this point on, the network information of WS4 stops flowing to the network line, and the network information of WS5 starts flowing. Therefore, in WSl, the network information storage area is updated as shown in Figure 2(b) and as shown in Figure 2(a).
By comparing with the identification number in Figure 2(b), the WS
Recognizes the stoppage of operation of WS4 and the start of operation of WS5.

Furthermore, WS2 started operating, and the printer connected to WS3 became WS2.
S5, then WS6 newly connects to network 2
It is assumed that the network is connected to the network and starts operating, resulting in the network configuration shown in FIG. The network information storage area in WSI is updated to FIG. 2(d) via FIG. 2(c). At this time, W S 2 .

WS 3. WS5. V=“S6 network information storage areas are respectively equal to those shown in FIG. 2(d).

〔Effect of the invention〕

As described above, the present invention has a mechanism for constantly retaining various information in the network, so that it is possible to flexibly deal with changes in workstations in the network, resources held by the workstations, and the like.

Furthermore, the existence of available resources within the network can be accurately recognized.

Furthermore, in terms of network management, each workstation has the advantage of being able to grasp the status of the entire network.

Claims (1)

[Claims] 1. In a network where multiple workstations are connected and can communicate with each other, communication and resource information held independently by each workstation is constantly provided to each workstation, and the above information is transmitted to each workstation. A network information retention method characterized in that workstation users are made aware of communicable workstations and effective resource information within a network by collecting and retaining information.
