Abstract

PURPOSE:To simplify the common resource of a server and to improve the operability by allowing the user of the system to register its group name, to receive a packet, to analyze the content of the packet and to connect to the server, and using minimum resources in common. CONSTITUTION:A server 32 sends its own name to a network system in terms of a broadcast type periodically. Thus, the server 32 and each personal computer 36 belonging to the network system receive the message to recognize the server name and attains the establishment of at least a virtual line. Moreover, after the data of a name packet send by the server 32, the abbreviated name of the minimum resource allowed by the server 32 is added and it is sent to the network system in terms of the broadcast type. Thus, even a personal computer 36 of other network system can use the resource of the server 32 when the group name of the relevant system is known and then the operability is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a local area network system (
The present invention relates to a LAN system control method, and particularly to a LAN control method that can simplify shared resources of servers and improve operability.

[Conventional technology]

A conventional LAN system, for example, as shown in Figure 2,
External storage device 21 storing shared resources, server (SRV
) 22% Multiple personal computers (PC, ~P
C,) Consists of 23-25.

In such a configuration, when the PCs share the resources of the server 22, a common method is to create a link between the server 22 and PC1 to PC1 by creating a virtual line. In this case, it was necessary to know the network name of the server providing the resource and the abbreviation of each resource. Therefore, if a system user forgets the server name or if a server administrator changes the server name, connection may become impossible.

Furthermore, if the system is connected to a different network system (a group that shares resources around a server other than the server 22), the shared resources of other groups cannot be used via that server.

Regarding conventional LAN, for example, "Current status and future prospects of LAN," Takuo Aiuchi, Computer networks and LAN, separate volume (May 1985).

[Problem to be solved by the invention]

In the above conventional technology, in order to use shared resources of the server,
When attempting to establish a virtual line with a server, if the server salt is forgotten or the server salt is changed by the server administrator, the connection becomes impossible.

Furthermore, it was difficult to connect to servers with different network systems and use their resources.

The purpose of the present invention is to improve the above-mentioned problems and to improve the operability by simplifying the shared resources of the server.
An object of the present invention is to provide an AN control method.

[Means for Solving the Problem] In order to achieve the above object, the LAN control method of the present invention includes the following:
In a LAN system where resources managed by servers are shared and utilized, a unique group name is given to the network system centered on the server, and the server periodically uses its own unique name and the minimum shareable name. A packet containing the abbreviated name of the resource as data is sent as a broadcast type to the own network, and the system user registers the group name, receives the packet, analyzes the contents of the packet, and connects to the server. , is characterized by the sharing of minimal resources.

r Effect] In the present invention, the server periodically transmits its own name to the network system in a broadcast type.

This makes it possible for each personal computer belonging to the same network system as the server to receive the message, learn the server information, and establish at least a virtual line.

Also, after the name packet data sent by the server,
Add the minimum resource abbreviation allowed by the server and send it to the network system as a broadcast type.

As a result, even personal computers in other network systems can use the resources of that server if they know the group name of the system.

Therefore, it is possible to improve the operability by converting the server's shared resources into vI elements.

〔Example〕

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

FIG. 3 is a configuration diagram of a LAN system in one embodiment of the present invention, and FIG. 4 is an explanatory diagram of packet data in one embodiment of the present invention.

In FIG. 3, 31 is an external storage device, 32 is a server (
33 is a server (SRV), 34 to 39 are personal computers (PC4 to PC1), and 40 is an external storage device. Further, the server 32 and the personal computers 34 to 36 constitute a system A, and the server 33
The personal computers 36 to 39 constitute a system B, and the systems A and B are connected via the personal computer 36.

Further, the external storage device e31 stores resources shared by yarn A under the management of the server 32, and the external storage device 40 stores resources shared by yarn B under the management of the server 33.

In this embodiment, when the server 32 serving as the core of system A registers its own name (a unique name for the entire network, SRV), it also registers its name as a member of system A. Name indicating (A
BC).

Furthermore, when the network software starts up, the server 32 periodically sends messages to its own network (once every few seconds).
4), as shown in FIG. 4, a packet containing the user's unique name and the abbreviated name of the minimum shareable resource as data is transmitted in a broadcast type.

Note that the server administrator divides the hard disk owned by the server into directories, etc., assigns a name (abbreviation) to each directory, and assigns the abbreviation to each directory according to the grade assigned to personal computers on the same network. give. Further, the abbreviation of the minimum shareable resource is, for example, the abbreviation of a directory in which data, information, etc. that may be viewed by the public are stored.

Also, the server 33 of system B uses the same procedure as the server 32 to enter its own name and a name (XYZ) indicating that it is a member of system B when starting up! ! After that, it periodically sends a broadcast type packet containing its unique name and the minimum shareable resource abbreviation as data.

Furthermore, when the personal computer 34 of system A starts up the network software, it registers the names PC4 and ABC, similarly to the server 32. Furthermore, by receiving packets periodically transmitted by the server 32, the server name (SRV, ) of system A can be known. Thereafter, the personal computer 34 shares the resources of the server 32 based on the approximate shared resource given to the server 32 in advance.

Note that the other personal computers 35 to 39 also start up using the same procedure, learn their own server names, and share their resources.

Next, we will discuss how to connect to servers with different network systems.

FIG. 1 is an explanatory diagram showing connections with other servers in an embodiment of the present invention.

In this embodiment, when accessing the server 32 of system A from the personal computer 37 of system B, the processing procedure is shown in FIG.

That is, the server 32 enters the server name (S
After registering the name (ABC) of RV O) and system A (1
01, 102), sends a packet with the configuration shown in Figure 4 to system A in broadcast type (103)
.

Furthermore, the personal computer of system A also registers its own name and the name of system A (ABC). For example, the personal computer 34 registers pc and ABC (111, 112). Thereafter, it receives the packet sent by the server 32 (113), establishes a virtual line with the server 32 (114), and shares/uses its resources.

On the other hand, when the personal computer 37 loads the network software, it registers the unique name PC and the network system B group name XYZ (121, 122).

Furthermore, since the server 32 is a server of a different network system, it also registers the group name ABC of network system A (123), thereby receiving the packets that the server 32 periodically sends (124). By analyzing the data of the packet (server name and approximate angle) and connecting to the server 32 (125), the minimum resources allowed by the server 32 can be shared.

Note that if the personal computer 37 wishes to share resources at a higher level than the minimum level permitted by the server 32, it is necessary to obtain permission from the administrator of the server 32 (obtain the approximate name of the resource it wishes to share). There is.

In this embodiment, by providing the LAN system with a guest function (a function that allows you to use the functions and information of each BBS at a minimum without knowing the LOGIN name), which is generally performed in BBSs, etc., servers of different systems can shared resources can be easily used.

【Effect of the invention〕

According to the present invention, it is possible to connect to the server even if the server name is forgotten or the server name is changed. Furthermore, the work of establishing a virtual line can be simplified.

Also, just by specifying the network group name,
It is possible to connect to servers of different systems and share resources. This makes it possible to obtain information on other systems and prevent access to important resources.

Therefore, it is possible to simplify the shared resources of the server and improve operability.
