Abstract: Network repeaters which each implement a redundant switching function previously grasp connection states of ports of a network system by using an inquiry frame and an exchange frame. At the time when a line is broken, when actively confirming a state of a port connected to a port in which a line is broken via a downstream device, the network repeaters each grasp that which portion of the line is broken and determine whether a switchover is required. Through the process, the network repeaters each prevent a useless switchover such as switching-back immediately after the switchover, and at the same time since a mechanism of waiting for a given length of times is not required, they each perform a fast switchover.

Abstract translation: 每个实现冗余切换功能的网络中继器先前通过使用查询帧和交换帧来掌握网络系统的端口的连接状态。 当线路断开时，当通过下游设备主动确认连接到其中线路断开的端口的端口的状态时，网络中继器各自掌握线路的哪个部分被破坏并且确定是否切换 是必须的。 通过该过程，网络中继器在切换后立即避免无切换的切换，如切换回切，同时由于不需要等待一段时间的机制，因此它们各自进行快速切换。

Abstract: A circuit arrangement and method utilize existing redundant execution pipelines in a processing unit to execute multiple instances of stability critical instructions in parallel so that the results of the multiple instances of the instructions can be compared for the purpose of detecting errors. For other types of instructions for which fault tolerant or stability critical execution is not required or desired, the redundant execution pipelines are utilized in a more conventional manner, enabling multiple non-stability critical instructions to be concurrently issued to and executed by the redundant execution pipelines. As such, for non-stability critical program code, the performance benefits of having multiple redundant execution units are preserved, yet in the instances where fault tolerant or stability critical execution is desired for certain program code, the redundant execution units may be repurposed to provide greater assurances as to the fault-free execution of such instructions.

Abstract translation: 电路布置和方法利用处理单元中的现有冗余执行流水线并行执行稳定性关键指令的多个实例，从而可以比较指令的多个实例的结果以便检测错误。 对于不需要或不需要容错或稳定性关键执行的其他类型的指令，以更传统的方式利用冗余执行流水线，使多个非稳定性关键指令同时发布到冗余执行管线并由其执行 。 因此，对于非稳定性关键程序代码，保留具有多个冗余执行单元的性能优点，但是在需要对某些程序代码进行容错或稳定性关键执行的情况下，冗余执行单元可以重新利用以提供 对这种指令的无故障执行的更大保证。

Abstract: To facilitate dynamic lockstep support, replacement states and/or logic used to select particular cache lines for replacement with new allocations in accord with replacement algorithms or strategies may be enhanced to provide generally independent replacement contexts for use in respective lockstep and performance modes. In some cases, replacement logic that may be otherwise conventional in its selection of cache lines for new allocations in accord with a first-in, first-out (FIFO), round-robin, random, least recently used (LRU), pseudo LRU, or other replacement algorithm/strategy is at least partially replicated to provide lockstep and performance instances that respectively cover lockstep and performance partitions of a cache. In some cases, a unified instance of replacement logic may be reinitialized with appropriate states at (or coincident with) transitions between performance and lockstep modes of operation.

Abstract: A system and method are disclosed for maintaining a plurality of data storages coherent with one another for redundancy purposes. The system includes a first data storage system and a second data storage system. The first data storage system is coupled to a first transaction processor for handling input and output transactions, and is coupled to a wide area network. The second data storage system is coupled to a second transaction processor for handling input and output transactions, and is coupled to the wide area network. The first transaction processor permits a first data write transaction to occur with respect to data within the first data storage system, and the second transaction processor permits a second data write transaction to occur with respect to data within the second data storage system. The first transaction processor permits the second data write transaction to occur with respect to data within the first data storage system only upon data consistency between the first and second data storage systems being validated. The second transaction processor permits the first data write transaction to occur with respect to data within the second data storage system only upon data consistency between the first and second data storage systems being validated.

Abstract: A system having multiple execution units and a method for its changeover are provided. The system having multiple execution units has at least two execution units, and may be changed over between a performance operating mode, in which the execution units execute different programs, and a comparison operating mode, in which the execution units execute the same program. The system has a scheduler, which is called by an execution unit to ascertain the next program to be executed. The remaining execution units are prompted to also call the scheduler if the program ascertained by the first called scheduler is to be executed in a comparison operating mode. A changeover unit changes over the system having multiple execution units from the performance operating mode into the comparison operating mode if the program to be executed ascertained by the last called scheduler is to be executed in the comparison operating mode, this ascertained program to be executed being executed as the program having the highest priority by all execution units after the changeover of the system into the comparison operating mode.
