基于响应系统的软件容错支撑系统及其仿真研究

The Study of Software Fault-Tolerant Supporting System and Its Simulation Based on Responsive System

首先提出将容错功能与实时功能相结合的响应系统概念及基于响应系统的软件容错支撑软件系统，其次，提出能克服N版本致命缺点即双重错误的基于一致性恢复块的软件容错方案最后通过由4台微机构成的仿真系统验证了基于响应系统的软件容错支撑软件系统的可行性．

A concept of responsive system combining fault tolerance with real-time perfrmoance and the software fault-tolerant supporting system based on responsive system are presented first, a scheme of consensus recovery block is then proposed to overcome the same errors fatal tO N-version programming technique in two versions. Lastly, the feasibility of the software fault--tolerant supporing software system based on responsive system is finally verified by the simulation system consisting of four computers.
