摘要
研究异常处理机制与分布式实时处理相关的指标及构件，分析目前的异常处理机制类型及特点，提出基于消息端口的分布式实时系统异常处理机制。该机制基于消息服务器和喘口变量通信机制，首次实现动态可重构的Ｏ（１）时限分布或异常处理。
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.
