Abstract. An approach is proposed for estimation of upper limit of message delivery time for separate sites in distributed real-time systems on the base of CAN-interface. It is shown that methods analogous to those used to check assurance of task performance timeliness in uniprocessor real time systems, may be applied for checking in time communication between sites in systems under consideration.
Keywords: real-time systems, distributed program complex, CAN-interface, task performability.
