PURPOSE: To quickly retire from a congestion state of processors for an electronic switchboard of multiprocessor system, by controlling a control load to the processor in a congestion state for each processor under control.
CONSTITUTION: The function of an electronic switchboard of multiprocessor system is shared by plural processors LPR, CPR and MPR. A means HT is provided to the switchboard to monitor an abnormal congestion state for the above- mentioned processors and then transmits the control command of the control load to these processors which are in the ongestion state via an exclusive command line L2 reaching each processor. As a result, each processor under control command can control the control load to the processor in the congestion state. In such way, the processor can quickly be retired from the congestion state.
