Abstract

PURPOSE:To improve the mean communication through of all communication devices by providing an execution control switching means which switches the execution control of a communication processing means according to the generation rate of a communication processing request. CONSTITUTION:The execution control switching means 8 checks the generation rates of communication processing requests to the communication devices 6 and 7 and switches the communication processing means 6 and 7 under the control of an execution control means 1. Then the generation rate of the communication processing requests to the communication devices 6 and 7 is researched and when the generation rates exceed a predetermined value, the execution control switching means 8 switches the communication processing means 6 and 7 under the control of the execution control means 1. Consequently, only the communication processing request to one specific communication device 6 or 7 is not processed for a long time and the communication processing request to the other device 7 or 6 is processed speedily to improve the mean communication throughout of all the communication devices.

Problems to be Solved by the Invention However, the above-mentioned configuration is not suitable for cases where communication processing requests for a particular communication device occur intensively and the number of communication processing requests retained in the processing request receiving means increases extremely. It takes a long time for the communication processing means to process all the processing requests accumulated in the processing request receiving means. Processing priority is given to the communication device that had the problem that communication processing requests for other communication devices are waiting to be processed. A similar problem occurs between communication devices with the same priority in a communication processing execution device in which there is L.A Similar problem occurs between communication devices with the same priority a.The present invention takes this point into account when communication processing requests to a specific communication device occur intensively.耘 The purpose of this invention is to prevent other communication devices from waiting for long periods of time for processing.The purpose of the present invention is to provide a communication processing execution device that can execute communication processing at high speed from the viewpoint of the entire communication processing execution device. Means To achieve the above object, the communication processing execution device 1 according to the present invention checks the occurrence rate of communication processing requests to each communication device and executes communication processing with execution control switching means for switching the communication processing means executed by the execution control means. The present invention uses the above-described configuration to check the occurrence rate of communication processing requests to each communication device, and when this occurrence rate becomes larger than a predetermined value, the execution control switching means performs a switching process to Switching the communication processing means executed by the execution control means prevents communication processing requests for a specific communication device from being processed for a long time, and processes communication processing requests for other communication devices at high speed. By doing so, the average communication processing efficiency of all communication devices can be improved.Although FIG. 1 is a block diagram showing the configuration of a communication processing execution device in an embodiment of the present invention, FIG. The same number is used for the same item. 7)c, 6(7) is -22(
3) is a processing request receiving means; l is an execution control means; 4 (5) is a communication processing means; and 8 is an execution control switching means for switching the communication processing means to be executed.

The processing request receiving means 2 which has received the communication processing request generates an execution control request (step 23), and drives the execution control means 1 (step 26). If the execution control means 1 is already executing the communication processing means, it waits until the processing is completed (steps 24 and 25). The execution control means 1 driven by the execution control request communicates with the communication processing means 4 to be subject to execution control.
The communication processing means 4 takes out the communication processing request from the processing request receiving means 2 and performs communication processing with the communication device 6 (step 29.30). When the communication processing means 4 finishes processing the communication processing request, it checks whether a switching processing request has occurred (step 28). When a switching processing request is generated, execution of the communication processing means 4 is terminated and switching processing is performed (step 31).

If no switching request has occurred, check whether there are any communication processing requests that are accumulated in the processing request receiving means 2. If there are communication processing requests that are accumulated, the communication processing means 4
retrieves and processes the accumulated communication processing requests in order.
The process is repeated until there are no pending communication processing requests (steps 28, 29, 30). If there is no communication processing request pending in the processing request receiving means 2, the execution of the communication processing means 4 is ended and the execution control means 1 is stopped (step 32).

FIG. 3 is a flowchart when the execution control switching means 8 generates a switching processing request, and the operation will be explained below. The number of processing requests is monitored and compared with a predetermined "maximum retention value" (steps 31 and 32).When the number of pending communication processing requests is greater than the "maximum retention value", the In order to process the communication processing request, a switching processing request is generated (step 33).Even if the switching processing of the execution control means 1 is performed due to the generated switching processing request, the execution control switching means 81 is used to terminate the switching processing that has been performed. The number of communication processing requests accumulated in each processing request receiving means is monitored and compared with a predetermined "minimum accumulation value" (step 34.35). When the value becomes smaller than the retention value °, a switching processing request is generated again (step 36).The switching processing of the execution control means 1 is terminated by the generated switching processing request. Fig. 4 is a flowchart of the switching processing performed by the execution control switching means 8. The operation will be explained below. First, when a switching processing request occurs, the execution control switching means 8 checks the processing request receiving means in which the communication processing request is pending (step 42). If the request receiving means 3 is present, the execution control switching means 8 switches the execution control target of the execution control means 1 to the communication processing means 5 (step 43).Then, the execution control means 1 executes the processing of the communication processing means 5.
