Abstract: Methods are disclosed for improving communications on feedback transmission channels, in which there is a possibility of bit errors. The basic solutions to counter those errors are: proper design of the CSI vector quantizer indexing (i.e., the bit representation of centroid indices) in order to minimize impact of index errors, use of error detection techniques to expurgate the erroneous indices and use of other methods to recover correct indices.

Abstract: Embodiments are directed to predicting the health of a computer node using health report data and to proactively handling failures in computer network nodes. In an embodiment, a computer system monitors various health indicators for multiple nodes in a computer network. The computer system accesses stored health indicators that provide a health history for the computer network nodes. The computer system then generates a health status based on the monitored health factors and the health history. The generated health status indicates the likelihood that the node will be healthy within a specified future time period. The computer system then leverages the generated health status to handle current or predicted failures. The computer system also presents the generated health status to a user or other entity.

Abstract: Disclosed herein is a method of managing the path of an OSEK network. The method of managing the path of an OSEK network includes step S1 at which a message is transferred along nodes of the OSEK network; step S2 at which a failed node at which a network failure has occurred is detected while the message is being transferred at step S1; step S3 at which the failed node of step S2 is eliminated from the overall network; and step S4 at which the message is transferred from a source node that has transferred the message to the failed node of step S2 to a target node to which the failed node will transfer the message by connecting the source node with the target node.

Abstract: Detecting error states when interacting with web applications is performed by accessing a first web page of a web application, determining that the first web page includes an input validation operation, configuring an input to cause the input validation operation to effect an error state, providing the input to the first web page, thereby effecting the error state, identifying a feature that is absent from the first web page before the input is provided to the first web page and present in the first web page after the input is provided to the first web page, and detecting that a second web page of the web application is in an error state if the feature is present in the second web page.

Abstract: A method, system and computer program product are provided for implementing concurrent adapter driver maintenance and recovery for a Single Root Input/Output Virtualization (SRIOV) adapter in a computer system. An adapter driver at start up time performs configuration of the adapter and each of a set of virtual functions (VFs). The adapter driver writes critical adapter and VF configuration data to a scratchpad buffer. When device driver maintenance is needed, such as to load updated adapter driver firmware, all VF drivers are held off temporarily, current adapter driver is detached, and then the adapter driver is reloaded with the updated driver firmware. Then the adapter driver is restarted with the updated adapter driver firmware, and performs a reinitialization process. The adapter driver performs adapter and VF configuration restoring existing configuration using values read from the scratchpad buffer.
