Fault-tolerance and fault-containment models for zoning clustered application silos into continuous availability and high availability zones in clustered systems during recovery and maintenance

InactiveUS20070006015A1No impact on transaction processingSmall sizeError detection/correctionTransmissionFault toleranceIslanding
A cluster recovery and maintenance system, method and computer program product for use in a server cluster having plural nodes implementing a server tier in a client-server computing architecture. A first group of N active nodes each run a software stack comprising a cluster management tier and a cluster application tier that actively provides services on behalf of one or more client applications running in a client application tier on the clients. A second group of M spare nodes each run a software stack comprising a cluster management tier and a cluster application tier that does not actively provide services on behalf of client applications. First and second zones in the cluster are determined in response to an active node membership change involving one or more active nodes departing from or being added to the first group as a result of an active node failing or becoming unreachable or as a result of a maintenance operation involving an active node. The first zone is a fault tolerant zone comprising all active nodes that remain operational. The second zone is a fault containment zone comprising all active nodes participating in the membership change and at least a corresponding number of spare nodes to the extent that the membership change involves a node departure. During recovery and maintenance, fast recovery/maintenance and high application availability are implemented in the fault containment zone, while continuous application availability is maintained in the fault tolerant zone.

System and method for integrating and controlling audio/video devices

A processor integrating and controlling at least two A/V devices by constructing a control model, referred to as a filter graph, of the at least two A/V devices as a function of a physical connection topology of the at least two A/V devices and a desired content to be rendered by one of the at least two A/V devices. The filter graph may be constructed as a function of at least two device filters corresponding to the at least two A/V devices, in which the device filters include certain characteristics of the at least two A/V device. These characteristics may include the input or output pins for each device, the media type that the A/V device may process, the type of functions that the device may serve, etc. The desired content may be received as a user input which is entered via a keyboard, mouse or other comparable input devices. In addition, the user input may be entered as a voice command, which may be parsed by the processor using conventional speech recognition algorithms or natural language processing to extract the necessary information. Once the filter graph is constructed, the processor may control the at least two A/V devices via the filter graph by invoking predetermined operations on the filter graph resulting in the appropriate commands being sent to the at least two A/V devices, thereby results in the rendering of the desired content.
