Abstract

PURPOSE:To smoothen processing load pertinent to data transmission through a bus by constituting the titled system so that a CCP at each transmission source varies its re-transmission time interval corresponding to the number of times of the re-transmission of transmission packets to the bus. CONSTITUTION:Each of the communication control processors CCPR1-CCPRn decides the destination of data inputted from a data communication line in the unit of packet, and, upon necessity, transmits, through a system bus 200 the to data such CCP that contains an out line. When a CCPRi receives one piece of packet, it transmits a reception information to a transmission source a CCPsk for instance. Each of the transmission source CCPs, in case no reception information is returned within a prescribed time t0 after the packet transmission to the bus 200, re-transmits this packet after the said time lapse: T=t0+t1. The transmission-side CCP counts the time untill this re-transmission of a trans mission packet, and changes the response-waiting time untill the time of re- transmitting to the bus 200 corresponding to said counted time.
