A distributed data processing system including a general, communications network, and a plurality of local systems which each include a central processing unit, associated memory, and at least one peripheral device. The control of the intercommunication is effected by respective systems intercommunication processors, each attaching one local system to the network. Each SIP has a programmed processor, a local and a network interface, and a bidirectional buffer. The system intercommunications processor will provide for address and code parameter translation, resource requesting and allocating access granting and protecting of the local resources and information objects, while sharing resources among plural requesters. Also failure management and control panel simulation is effected by the systems intercommunications processor.
