ABSTRACT:
Device abstraction units28aand28brespectively transmit various pieces of control information and data to and from devices34aand34b,and carry out abstraction of the devices34aand34b(that is, abstraction of the hardware) with respect to upper constituents. Interface units22aand22btransmit various pieces of control information and data to and from the device abstraction units28aand28b,and provide an application unit20with an identical interface. Communications path abstraction units24aand24bcarry out abstraction of communications paths26aand26bin the process of transmission of various pieces of control information and data via the communications paths26aand26bacross a process boundary or a network boundary. This arrangement of the present invention enables a substantially fixed control according to an applications program, regardless of the type of the device or the type of the communications path.
