摘要
针对数据链性能质量和服价问题 ,提出一种基于可靠性理论的数据链用户冗余策略 ,并建立数学模型 .模型综合平衡了冗余运行和正常维护的关系 ,从而大大改进了系统的性能 .模型采用一定的状态检查和验证策略 ,有效保证网络的正常工作 .设备之间各自独立 ,相互协作 ,合作完成容错任务 .该模型与特定的系统应用环境无关 ,提供了一个通用的容错系统框架 。
To solve the datalink problem of capability and service/price, a framework model - a new datalink user's redundant strategy was proposed, based on reliability theory. The redundant strategy could be combined with the normal maintenance, which greatly improved the performance of the network system. The static-checking and policy of authentication mechanism ensured the running network without any error. The redundant equipment were independent but were capable of communication with each other when they work their actions. The model was independent of specific application environment, providing a general-purpose framework for fault diagnosis. An example was given to express the calculating method.
