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 methods to achieve redundancy of HSDB network medium are proposed: complete dual-bus redundancy, synchronous redundancy and backup redundancy. Two different implementation methods of synchronous redundancy are analyzed in detail: synchronization of data-oriented redundancy and Data Oriented Redundant Synchronization Process. Finally, we choose the data redundancy oriented redundancy to achieve HSDB network media redundancy.
