ABSTRACT:
The present invention is directed to an information processing system composed of plural information processing units adapted for mutually executing data communication, and for executing data processing in which communication data has been applied. The first entity A transmits error notification data on the basis of error detection to execute initial state return processing on the condition that data reception after error notification data has been transmitted is made, and the second entity B transmits error notification data on the basis of error detection to execute initial state return processing on the condition that transmit processing of error notification data is executed. Thus, the both entities A and B can return to the initial state in a manner synchronous with each other. As a result, it becomes possible to perform reliable error recovery and data processing restart.
