【Abstract】 The function and the status of the malfunction check technology in the distributed real time system is described, and subjunctive fixture token ring time protocal is introduced. The method and achieving technology for checking the node′s malfunction in the system by using the systems maintaining for the subjunctive token ring is studied. This method and technology can offer node"s malfunction message for distributed real time tolerance fault transaction program, so DRT UNIX can have a good tolerance fault capability.更多还原
