ABSTRACT:
In an intercommunication network for use in transmitting a transmission request from a first processor to a second processor, the first processor sends a first processor number preassigned thereto through a system bus to the second processor which holds a communicable processor number corresponding to the first processor number and which detects whether or not the first processor number indicates the first processor by monitoring correspondence between the first processor number and the communicable processor number. A destination processor number assigned to the second processor may not be transmitted from the first processor because identification is made in the second processor. Thus, no destination processor number is administrated in the first processor. The first and the second processors may belong to a lower rank and an upper rank, respectively, and may be an input/output processor and an execution processor unit, respectively.
