| Abstract: | This paper studies the index and component of Exception Handling Mechanism(EHM) for distributed real time system. The c;ltegory and featUres of present EHMs are also analyzed. A new EHM based on message port for distributed real time system is developed. Based Inn message server and port variable communication mechanism. the new EHM realizes dynamic reconfigurable O(1)distlibuted exception handling for the first time. |
