Abstract

PURPOSE:To equally secure storage areas of constant capacity for respective clients by reducing the load of processing on a network controller by facilitating the registration of a new client, and securing its storage capacity on a file server at the time of the registration. CONSTITUTION:In the server and client type network system equipped with plural terminals WST1-WST3 which constitute the clients and the server SVR shared by the terminals, the server is provided with a network control table; when the client logs on the system for the 1st time, the server registers the network address and terminal name of the client in the network control table and the network is controlled thereafter according to the control table. When the new client is added, the registration of the client is automatically performed by the 1st logging-on process, so the load on the network controller is reducible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a server-client type network system, and more particularly to reducing the processing load of a network administrator and fair allocation of a storage area of a file server to each client.

[0002]

2. Description of the Related Art Conventionally, in a server / client network system, when newly registering a client, information of the new client is registered in advance on the server side, and in the file server, up to what level of file access is performed. Had to register or allow.

[0003]

In the above conventional technique, a network administrator manages a server, registers a network address, a workstation (terminal) name, etc. for a new client, and further, in the case of a file server. Has to register which areas on the server are allowed to be accessed, and to notify the information to the users of each client, which poses a problem that the processing load on the network administrator is heavy.

Further, in the file server, when there is a user who has little knowledge of the network system or a malicious user, the client operated by the user occupies the storage area of the server, and other clients operate as the server. There was a risk that the storage area could not be secured above.

An object of the present invention is to provide a network system which facilitates registration of clients and which can fairly secure a storage area for each client in a file server with a fixed capacity.

[0006]

A network system according to the present invention is a server-client type network system comprising a plurality of terminals constituting a client and a server shared by the plurality of terminals. A management table is provided in the server, and when the client logs on to the system for the first time, the server registers the network address and terminal name of the client in the management table, and thereafter manages the network based on the management table. It is characterized by doing.

[0007]

According to the present invention, in order to newly register a client, the network administrator has only to decide a network address to be assigned to the client, and inform the user of the new client of this network address together with the information of the server. .. When a new client logs on to the network from the network address, the server automatically registers the network address and terminal name in the network management table. In addition, in the file server, when registering a new client, a storage area is secured by the default capacity designated by the network administrator, and the contents of this storage area are also registered in the network management table. As a result, the storage area will not run out due to the influence of other clients, and the client will not occupy the storage area of the server.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, FIG. 5 shows an example of a network system to which the present invention is applied. Here, a plurality of workstations WST1 to WST3 serving as clients are provided.
And a server SVR shared by these workstations are connected to the network NET.
The server SVR of this embodiment is a workstation WST.
And a file FILE.

FIG. 1 shows an example of the configuration of the network management table 5 provided in the file server SRV of the network system in this embodiment. The network management table 5 includes a network address 11 for identifying a client, a workstation name 12, and a server SV.
The storage area name 13 is provided for identifying the storage area secured on R, and the storage capacity 14 in which the capacity of this storage area is recorded is registered. In the example of FIG.
Three clients are registered. As will be described later, in this network management table 5, registration items of a new client are newly registered each time the new client logs on. The registered contents of the client once registered are retained even after the logoff.

FIG. 2 shows a state of each storage area secured on the server SVR. The storage area on the server SVR is a common area DIR that is commonly accessible by each client.
0, storage area DIR1 to 1 reserved for each client
It is composed of DIR3 and an unused area UNUSED.

FIG. 3 shows an algorithm of the logon processing of the file server.

First, when a client logs on to the file server, it is checked whether this logon is the first logon by the client (100). If it is not the first logon, the process proceeds to step 105, and if it is the first logon, the process proceeds to step 101. In step 101, in order to secure a storage area to be allocated to the client who has logged on for the first time, it is checked whether or not the unused area at that time is equal to or more than a predetermined value (default value). If so, go to step 104,
If not, the process proceeds to step 102. In step 102,
Performs processing to release the area of another client. However,
This release is performed only when the area of the other client has a capacity equal to or larger than the predetermined minimum value designated by the network administrator and there is an unused portion in the storage area. If this area is not secured (103), the logon is unsuccessful and the process ends (106). If the area is successfully secured, the area is secured for the client, and the various registration items described above are registered in the network management table 5 (104). In the following step 105, the secured client storage area and common area are connected to the client (that is, accessible by the client).

Now, consider a case where the client 1 of the NETADDR1 logs on in the registered state of the network management table 5 of FIG. In this case, NETADDR
Client 1 of 1 already has network management table 5
Since it has already been registered in step 100, it is determined in step 100 that it is not the first logon, and the process proceeds to step 105. Here, referring to the network management table 5, the common area DIR0 and the storage area DIR1 reserved for the client 1 are connected to the client.

Next, the network address is NETAD.
Consider a case where a new client 4 with DR4 and workstation name WST4 logs on. in this case,
Since the client 4 of NETADDR4 is not registered in the network management table 5, this client 4 is determined to be the first logon in step 100, and the process proceeds to step 101. If it is determined in step 101 that the unused area has a capacity equal to or larger than the default value of the client storage capacity designated by the network administrator, step 10
If no, go to step 102. In step 104, the storage area DIR for the new client 4
4 is secured and registered in the network management table 5.
After that, the process proceeds to step 105 described above. In step 102, another client is checked to have a capacity equal to or larger than the default minimum value designated by the network administrator, and
If there is an unused part in the storage area, the area is released. As a result, if the unused area on the server becomes equal to or larger than the default value and the area is successfully secured, the process proceeds to step 104 described above. If it fails, the process proceeds to step 106, and this logon process is unsuccessful. However, as an alternative, a method of connecting to the common area may be considered.

FIG. 4 shows an algorithm of the process of step 102 of FIG. First, step 107
Then, as a result of this area release processing, it is determined whether or not the unused area has been secured to a value equal to or larger than the default value, and if secured, this processing ends. If not secured, step 108
At step 109, the other clients registered in the network management table 5 are examined in order, and if the capacity of the storage area is larger than the preset minimum value at step 109, then step 112 is executed.
If not, proceed to step 110. In step 110, it is checked whether or not the processing of all the clients registered in the management table 5 is completed. If it is completed, it is determined that the area reservation has failed in step 111, and this processing is ended. If there are unprocessed clients, the process returns to step 107 again. In step 112, it is judged whether or not there is an unused part in this storage area. If there is no unused part, the process proceeds to step 110 already explained. If there is an unused part, this unused part is checked in step 113. Release more than the default minimum. Then, it returns to step 107 again.

The preferred embodiment of the present invention has been described above, but various modifications can be made. For example, a priority level is set for each client, and a default value of the storage area allocated for each priority level (step 101 in FIG. 3) and a default minimum value released to other clients (step 1 in FIG. 4).
09) can also be provided.

[0018]

According to the present invention, in a server / client type network system, when a client is newly connected to the network, the network administrator determines the network address of the new client, and the new client together with the server information. All you have to do is to tell the user of, and the burden on the administrator can be reduced.

Further, in the file server, the storage area is automatically secured by the default capacity designated by the administrator by the processing of the first logon of the new client, so that it is not affected by other clients. A certain storage capacity is guaranteed, and the storage area of the server is not occupied.
