| 摘 要： | 针对实时CORBA与容错CORBA模型融合在分布式实时嵌入式系统(DRE)中存在的问题，提出基于半主动复制策略的容错模型，应用到DRE中并进行相关测试。实验结果表明，采用半主动复制策略的模型相对其他复制策略可更好地支持实时系统，并能在保证实时要求的前提下为系统提供容错支持。

| Abstract: | Aimming at problems of the integration of RT CORBA and FT CORBA as the infrastructure for DRE systems are analysed, the real-time fault-tolerant model based on semi-active replication strategy is proposed and applied in DRE system. Correlative tests are done. Tests prove that the model which adoptes semi-active replication is better suited for real-time systems than other replication strategies, and it can offer fault-tolerant support to system on the premise of assuring real-time requirements. |
