Process execution method and apparatus
Periodic process scheduling method of computer system includes steps of receiving requests for periodical execution of processes each with period of execution and execution time, securing allocation time for process having shorter period than the other processes to be executed in each of respective periods of execution for process, securing another allocation time for part of another process within first of respective periods of execution of process other than allocation time in first of the allocation time for process if full execution time of another process cannot be secured within first of respective periods of execution of process, and starting execution of process in secured allocation time and another process in secured another allocation time. A data transfer management method for effectively reducing collision in data transfer includes steps of storing data length (M) of packets capable of being transferred in predetermined transmission time interval, storing predetermined transmission time interval (t), accumulating quantity of packets to be transferred on communication stream in predetermined transmission time interval, and limiting quantity of packets to be transferred to value not greater than data length.
