Abstract

PURPOSE:To prevent an ineffective communication request processing to improve the processing capability and resolve the service delay, by holding availability information of connection parts of all master and slave subsystems in each slave subsystem of the distributed processing system consisting of a loop transmission line. CONSTITUTION:Availavility information of connecting devices Al-An, Bl-Bn, Cl-Cn, and Dl-Dn of all master and slave subsystems A'-D' included in the distributed processing system are always transferred from the main subsystem A' to slave subsystems B'-D' at a prescribed period. Consequently, when a communication request is received from a storage terminal equipment T, a subsystem control table ST in the subsystem itself is referred to discriminate the available state of connecting devices of the subsystem to be called immediately. Thus, the ineffective communication request processing where an unoperatable connecting device is used is avoided.
