    摘要： Various embodiments enable redundant or replica services, such as “cloud” services, to be run at geographically distributed locations. Each replica is capable of performing operations that are generally, identically performed across all replicas. In the event of an interruption at one location, services in other locations can quickly and automatically take over operations. In one or more embodiments, a Distributed Agreement Protocol is utilized to bind a CRUD-type protocol as a state machine. Binding takes place through the use of a reverse proxy that is located at each of the locations at which the service is distributed. In at least some embodiments, the Distributed Agreement Protocol is implemented as the Paxos protocol or a variant thereof, and/or the CRUD-type protocol comprises the HTTP protocol.

    摘要： A computer system includes a plurality of computer nodes, each including an external communications unit. An application unit executes processing in accordance with a processing request. A synchronization unit establishes synchronization of the processing between each computer node and other computer nodes. The processing is executed by each computer node, and an inter-node communications unit executes transmission/reception of information between each computer node and the other computer nodes. The synchronization unit transmits the processing request to the other computer nodes via the inter-node communications unit, the processing request being received by the external communications unit. Also, the synchronization unit receives processing requests from the other computer nodes as well via the inter-node communications unit. Based on the number of the computer nodes that have received the same processing request via the external communications units, the synchronization unit selects a processing request that should be executed by the application unit.

    摘要： A method, system, and computer program product for maintaining reliability in a computer system. In an example embodiment, the method includes managing workloads on a first processor with a first processor architecture by an agent process executing on a second processor with a second processor architecture. The method proceeds by activating redundant computation on the second processor by the agent process. The method continues by performing a same computation from a workload of the workloads at least twice. Finally, the method includes comparing results of the same computation. In this embodiment the first processor is coupled the second processor by a network, and the first processor architecture and second processor architecture are different architectures.

    摘要： The systems and methods of the present invention provide a solution that makes data provably secure and accessible—addressing data security at the bit level—thereby eliminating the need for multiple perimeter hardware and software technologies. Data security is incorporated or weaved directly into the data at the bit level. The systems and methods of the present invention enable enterprise communities of interest to leverage a common enterprise infrastructure. Because security is already woven into the data, this common infrastructure can be used without compromising data security and access control. In some applications, data is authenticated, encrypted, and parsed or split into multiple shares prior to being sent to multiple locations, e.g., a private or public cloud. The data is hidden while in transit to the storage location, and is inaccessible to users who do not have the correct credentials for access.

    摘要： A method of identifying a valid version of a data value and voting on separate instances of the data value is described. A processor receives an instance of the data value generated by one processor and a transmitted version of that generated instance transmitted by another processor and compares the received values to validate them. The processor further determines an agreed version of the data value from a comparison of the validated instances. As a result a simple and robust voting system is provided.

    摘要： Read, write and recovery operations for replicated data are provided. In one aspect, a system for redundant storage of data included a plurality of storage devices and a communication medium for interconnecting the storage devices. At least two of the storage devices are designated devices for storing a block of data. Each designated device has a version of the data and a first timestamp that is indicative of when the version of data was last updated and a second timestamp that is indicative of any pending update to the block of data. The read, write and recovery operations are performed to the data using the first and second timestamps to coordinate the operations among the designated devices.

    摘要： Systems and methods for redundancy management in fault tolerant computing are provided. The systems and methods generally relate to enabling the use of non-custom, off-the-shelf components and tools to provide redundant fault tolerant computing. The various embodiments described herein, generally speaking, use a decrementer register in a general purpose processor for synchronizing identical operations across redundant general purpose processors, execute redundancy management services in the kernels of commercial off-the-shelf real-time operating systems (RTOS) running on the general purpose processors, and use soft coded tables to schedule operations and assign redundancy management parameters across the general purpose processors.
