In such dynamic systems, predictability can only be achieved by proper architectural support that embodies adequate mechanisms and policies within the operating system. The authors present the design and implementation of predictable transport level communication services supported by the kernel of a real time distributed operating system (RTDOS). RTDOS IPC services are built on a hybrid platform, involving both message- and circuit-switching. Experimental results showed that RTDOS IPC was able to deliver millisecond-level connection times, guaranteed within the prescribed limits of system configuration.en-USCircuitsIntelligent NetworksReal Time SystemsOperating SystemsKernelCommunication SwitchingJoining ProcessesCommunication System Traffic ControlEducational InstitutionsComputer NetworksDistributed Real-Time SystemsPredictabiliqCircuit-SwitchingTransputer NefworksReal-Time SystemsDistributed ProcessingTransputer SystemsOperating Systems (computers)Distributed SystemsCircuit-Switching MechanismInterprocess CommunicationTransputer NetworkReal Time SystemTransport Level CommunicationReal Time Distributed Operating SystemRTDOSconferenceObject
