BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an embodiment of the distance learning system of the present invention. This remote learning system includes a learner's terminal 1 including a client application 2 and a learner information transmitting device 3 (which may be installed inside or outside the learner's terminal 1), and a server A having a server application A1. And a server B having server applications B2 and B3, a destination information server 6 having destination information 7 of the server applications A1, B2 and B3, and a network 8 connecting these. The learner learns using the server application A of the server A, the server application B1 and the server application B2 of the server B. That is, the learner uses server applications stored in different servers. The server applications cooperate with each other to provide a learner with a learning environment.
[0036]
The learning information transmitting device 3 is called from the destination information server 6, reads out the destination information 7 stored in the destination information server 6, stores it as the destination information 4, and, on the basis of the destination information 4, the required server A and server B. Connect to the application. The learning information transmitting device 3 stores retransmission information 5 generated when transmission of learning information has failed.
[0037]
The destination information 7 is stored in a server dedicated to the destination information, that is, the destination information server 6, and is executed. However, the same function may be provided by modifying one server application from a group of server applications to be used. good.
[0038]
FIG. 2 is an example of the destination information. The destination information includes a destination of the server application, an event such as a login, a transmission format of learning information, an allowable number of retransmissions, and information indicating whether a failure in the transmission process is fatal (criticality). The criticality is 1 if fatal, 0 if not fatal. As shown in FIG. 2, the destination information is stored in a line for each server application.
[0039]
The operation by the learner is processed by the client application 2 of the learner's terminal 1. When an event such as a login occurs, the learning information transmitting device 3 transmits the learning information input by the learner to any server application that needs to transmit according to the destination information.
[0040]
FIG. 3 shows a flow of processing for transmitting learning information to all server applications to be transmitted. When learning information is generated by a learning activity of a learner or the like, transmission of learning information using the learning information transmitting device 3 is started by the client application 2 (S1). Then, the destination information is read line by line (S2), and the learning information is transmitted to the destination (S3). Subsequently, it is confirmed whether the process has been completed up to the last line. If the process has been completed, the transmission process is completed (S5). If not, the process returns to step 2 (S2).
[0041]
FIG. 4 shows a flow of a process of transmitting learning information to one server application. When the learning information transmission process starts (S6), the learning information transmission device 3 recognizes the destination of the server application that needs to be transmitted, the transmission format, the allowable number of retransmissions, and the criticality based on the destination information 4 as shown in FIG. Then, based on the transmission format, the transmission format of the learning information is converted (S7), and the learning information is transmitted to the destination (S8). It is confirmed whether the transmission processing has been successful (S9), and if successful, the transmission processing ends (S10).
[0042]
When the transmission processing has failed, the learning information transmitting apparatus 3 determines whether transmission failure of the learning information to the server application is fatal based on the destination information 4 of FIG. 2 (S10). If the transmission failure for the server application that failed to transmit is fatal, the learning information transmitting device 3 notifies the learner of warning information (S13) and ends the transmission processing (S15). No warning is issued if it is not fatal. For example, if the transmission to the server application A1 fails, the failure is fatal according to the destination information 4, so that the learner is notified of the warning information. On the other hand, a failure in transmission to the server application B1 or B2 is not fatal, so that no warning information is issued.
[0043]
When it is determined that the transmission failure is not fatal, the learning information transmitting device 3 subsequently determines whether or not the transmission has failed more than the allowable number of retransmissions based on the destination information 4 in FIG. 2 (S11). . If the allowable number of retransmissions has already been reached, that is, if the allowable number of retransmissions in FIG. 2 is 0, warning information is notified to the learner (S13), and the transmission process is stopped (S15). If the allowable number of retransmissions has not been reached, no warning information is issued. For example, according to FIG. 2, the retransmission allowable number is two for any server application, so if the retransmission fails for the second time, the learner is notified of the warning information. No warning information is issued for the first time.
[0044]
If it is determined that the number of transmissions has not reached the allowable number of retransmissions, the learning information transmitting apparatus 3 then determines whether the size of the retransmission information 5 is equal to or greater than the processing limit of the retransmission information 5 of the learning information transmitting apparatus 3. Is determined (S12). If the size of the retransmission information 5 is equal to or larger than the limit, the learning information transmitting device 3 notifies the learner of warning information (S13), and stops the transmission process (S15). Conversely, if the number is equal to or less than the limit, no warning information is issued, and the learning information transmitting apparatus 3 retains a value obtained by subtracting 1 from the allowable number of retransmissions corresponding to the destination information of the server application for which transmission failed (S14). ). The learning information transmitting device 3 attempts to retransmit the server application that failed to transmit after a fixed time or after an event occurred by the learner.
[0045]
In the step shown in FIG. 4, at the same time that the learner is notified of the warning information, the warning information is also transmitted to another server application that has successfully transmitted the learning information, and stored as a log. The server application cooperates to provide the learner with a learning environment, thereby preventing the system from being disrupted.
[0046]
FIG. 5 shows a flow of the retransmission processing of the learning information. The learning information transmitting device 3 executes the retransmission process periodically or based on an event by the learner. In the learning information retransmission process, when the learning information retransmission is started (S16), it is first confirmed from the retransmission information 5 whether or not the retransmission allowable number has been reached (S17). If it has reached, the learning information is not retransmitted, and the retransmission processing ends (S22). If the retransmission allowable number has not been reached, the learning information transmitting apparatus 3 reads out all the retransmission information 5 into the buffer and clears the retransmission information 5 in the learning information transmitting apparatus 3 (S18). Next, the retransmission information 5 is read line by line from the buffer (S19), and the learning information transmission process of FIG. 4 is performed (S20). Finally, the learning information transmitting apparatus 3 checks whether or not all the retransmission information 5 in the buffer has been processed (S21). If the buffer is empty, the retransmission processing ends (S22), and the retransmission information 5 remains. If so, the process returns to S19 to continue retransmission.
