高速数据总线介质冗余方案的选择

Selection of Methods Implementing HSDB Media Redundancy

提出了实现HSDB网络介质冗余的3种方法：完备双总线冗余、同步冗余和备份冗余，详细分析了同步冗余的两种不同的实现方法──面向数据位的同步冗余和面向数据块的同步冗余的工作过程。最后选择面向数据块的同步冗余来实现HSDB网络介质冗余。

Three different methods implementing HSDB net-work media redundancy: full dual bus redundancy, synchronous redancy and standby redundancy are presented. Also, two approaches to implementation of the synchronous redundancy, data bit oriented implementation and data block oriented implementation are ana-lyzed in detail. Then, the data block oriented implementation of synchronous redundancy can be selected as an optimum method to implement HSDB network media redundancy.
