US 7,116,635 B2 · Process execution method and apparatus

Abstract

A periodic process scheduling method which includes receiving requests for periodical execution of processes each with a period of execution and execution time, securing allocation time for the shortest process to be executed in respective periods of execution, securing another allocation time for part of a process if full execution time of the process cannot be secured within the respective periods of execution, and starting execution of the process in secured allocation time. A data transfer management method for reducing collision in data transfer which includes storing data length of packets being transferred in a predetermined transmission time interval, storing the predetermined transmission time interval, accumulating a quantity of packets to be transferred in the predetermined transmission time interval, and limiting quantity of packets to be transferred to not be greater than data length.

Claims3

Dependent claims

An information processing apparatus, comprising:

a controller;
a first interface connected to a first network;
and
a second interface connected to a second network which is connected to a plurality of nodes each having a processor for transmitting data of an amount not larger than a predetermined value to said controller,
wherein said controller receives data from said first interface, limits a quantity of said data input through said first interface to be transmitted within a transmission through said second interface based on said predetermined value, receives data from said second interface, and transmits said data received from said second interface to said first interface.
