摘要: |
本文首先给出某高可靠、强实时分布式系统及系统的两种切换方案的简要描述, 然后对切换技术的实现进行讨论; 最后, 在建立强实时双工系统的可靠性模型基础上, 对系统的两种切换方案进行分析与比较。研究结果表明: 对于本系统, 机组级切换优于结点机级切换, 且可以减少程序的复杂度, 提高系统的可靠性与实时性。 |

Abstract: |
In this paper, a high reliability, a hard real-time distributed system and its two switch schemes are introduced at first. Then, the realization of switch technology is discussed. Finally, based on the reliability model of hard real-time dual working system, the two switch schemes are analyzed and compared. The conclusions show: The switch in cluster is superior to the switch in node, and it can not only improve the system reliability and real-time, but also reduce the complexity of the program. |
