Abstract

PURPOSE:To extremely decrease the number of clients to which distribution is not ended by performing the multi-destination delivery system of software resources plural times. CONSTITUTION:A master server 1 registers the software of the up-to-date version, and transmits software to be distributed, distributing data and hour, version, and the number of times of multi-destination delivery to servers 3 and 4 provided with clients 5. The servers 3 and 4 receive the data through a network 7, and performs the multi-destination delivery of the software to the subordinate clients 5 plural times according to the designated contents.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast distribution method for unifying versions of software resources in a client / server system connected to a network such as a LAN.

[0002]

2. Description of the Related Art Conventionally, various methods for efficiently and quickly distributing software resources such as programs and files to terminal devices have been proposed and put into practical use. For example, by dividing software resources into information unique to each terminal device and common information and distributing the common information by broadcast communication, a software resource distribution method (special feature) that shortens the distribution time to all terminal devices. Kaihei 4-195
No. 445), or a program distribution system (Japanese Patent Laid-Open No. 4-5749) in which a program distribution schedule is distributed to terminals in advance and the program is distributed according to this schedule.

[0003]

However, the above-mentioned conventional technique does not adopt a distribution method in consideration of the situation of the terminal device. In other words, there is a problem that the distribution of the software resource is not guaranteed if some trouble occurs on the terminal side or the power of the terminal is turned off at the time of distributing the software resource.

An object of the present invention is to provide a software resource broadcast distribution system in which the number of clients whose distribution has not been completed is minimized by performing the broadcast distribution of software resources a plurality of times.

[0005]

To achieve the above object, in the present invention, in a system in which a server and a client are connected via a network, the server is
It manages the latest software resources, distributes the software resources to the clients multiple times within a predetermined period, monitors the distribution results of all the clients after the distribution, and notifies the undistributed clients. On the other hand,
The feature is that the difference software resources to be updated are individually distributed.

[0006]

When the client cannot receive / store the software resource for some reason, the server again broadcasts the software resource at another time zone. The number of distributions is performed by specifying a command or the like. However, when the number of distribution clients is huge, some clients may not be distributed. The server knows to which client the distribution is completed and the distribution is completed by the completion message from the client. And
When communication is possible (distributable), the master server is notified of the version of the software resource that the client currently has, and the master server individually distributes only the differences to the clients. In this way, when the number of clients to be distributed is huge, the broadcast distribution is instructed n times, and the undistributed clients are individually distributed at the time of restarting. It becomes possible to remedy the problem, and the same version of software can be used for the entire system as much as possible.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a block diagram of a client / server system for carrying out broadcast distribution of software resources according to the present invention. In the figure, 1 is a master server which is positioned above each server, registers the latest software, and designates the number n of broadcast distributions, 2 and 3 and 4 are servers, respectively, and 2 is a client under it. Servers 3 and 4 which directly control individual processing without a server have servers k and m clients under them, respectively 5 are clients which receive and store the distributed software, 6 Is a line, and 7 is an L for connecting each server
A network such as an AN.

FIG. 2 is a flowchart of the broadcast distribution processing according to the present invention. That is, the master server 1 registers the latest version of software in a file (not shown) (step 100), and stores the registration date, version, software name, etc. in the file as management information (step 101). Then, in response to an operator's or program's instruction, the software to be distributed, the distribution date and time, the version, and the broadcast distribution count n are transmitted to the servers 3, 4 having the client 5 (step 102).

The servers 3 and 4 receive the transmission data via the network 7 and broadcast the software to the subordinate clients 5 according to the designated contents (step 103). For example, when the designated broadcast distribution number n is 3, the server 3 first performs the first broadcast distribution to k subordinate clients 5. At this time, the server 3 manages to which client the distribution is completed by receiving a completion message from the client.

If there is a client that has not been distributed due to the occurrence of a failure or power-off, unified version operation cannot be achieved in the entire system, so a predetermined period or a predetermined time is set (step 10).
4) The second distribution will be carried out and the relief will be implemented.
Even after the second broadcast distribution, if there is a client that has not been distributed, the third broadcast distribution is performed (step 105).

If the distribution is not performed even after the third time, the server lists the clients that could not be distributed (step 106). Next, when starting up the clients (step 107), the master server 1 knows the current software version of each client.
(Step 108), Only the software to be upgraded is individually distributed to each client as a difference.
(Step 109).

For clients that have not been distributed even by this individual distribution process (step 1
10), disconnect from the line 6 (step 111).

During the period in which the broadcast distribution is repeated three times, the system has a mixture of the client storing the old version software and the client storing the new version software. In other words, the master server monitors and controls so as to limit the provision of new service contents.

The server 4 also performs the same processing as described above. As described above, according to the software resource distribution method of the present embodiment, processing can be performed under the same version of the software environment as much as possible in the entire system.

[0015]

As described above, according to the present invention, when a software resource is broadcasted from a server to a client, the software resource is distributed a plurality of times, and the undistributed clients are individually distributed. Therefore, the number of clients to which software resources are not distributed can be reduced as much as possible, and the entire system can be operated with the same version.
