Abstract: In an error response circuit an analysis circuit unit analyzes a command transmitted from a first circuit section to a second circuit section, and detects a status of data transfer between the first circuit section and the second circuit section. A response circuit unit generates an error signal in accordance with the detected status of the data transfer in response to the second circuit section changing from a first power consumption state to a second power consumption state in which power consumption is lower than power consumption in the first power consumption state. A switching circuit unit transmits the error signal to the first circuit section in place of a response signal that is responsive to the command and transmitted from the second circuit section to the first circuit section.

Abstract: A communications system can provide methods of dynamically interleaving streams, including methods for dynamically introducing greater amounts of interleaving as a stream is transmitted independently of any source block structure to spread out losses or errors in the channel over a much larger period of time within the original stream than if interleaving were not introduced, provide superior protection against packet loss or packet corruption when used with FEC coding, provide superior protection against network jitter, and allow content zapping time and the content transition time to be reduced to a minimum and minimal content transition times. Streams may be partitioned into sub-streams, delivering the sub-streams to receivers along different paths through a network and receiving concurrently different sub-streams at a receiver sent from potentially different servers.

Abstract: Methods and apparatuses for enhanced protection of data stored in a non-volatile memory system involve a controller capable of adapting to the failure of one or more non-volatile memory devices in the memory system. The controller stores data in the form of page stripes, each page stripe composed of data pages, and each data page stored in a different non-volatile memory device. The controller also detects failure of a non-volatile memory device in which a data page of a particular page stripe is stored, reconstructs the data page, and stores the reconstructed data page in a new page stripe, where the number of data pages in the new page stripe is less than the number of data pages in the particular page stripe, and where no page of the new page stripe is stored in a memory location within the failed non-volatile memory device.

Abstract: Variations discussed herein pertain to identifying a resource usage of applications in a first data center; and for the applications in the first data center, writing those usages to a database. Variations also pertain to identifying a resource usage of applications in a second data center; reading the first data center loads from the database; determining, from the read loads, which applications in the first data center will fail over to the second data center should the first data center fail. For those applications, computing a shadow load that represents predicted computing resource requirements of those applications in the second data center based read loads; and developing a failover resource allocation scheme from the shadow load and a current local resource load of the second data center such that the second data center can take on the resource usage load of those applications if the first data center goes offline.

Abstract: A method and a computing system for performing the method. Microstates of components of a computing system are organized into macrostates of the computing system. Each microstate represents a state that a component of the computing system is able to individually enter. Each macrostate represents a state that the computing system is able to enter as a whole. The macrostates of the computing system are organized into meta-dynamic states of the computing system. The computing system is monitored such that perturbations of the computing system are detected, wherein a perturbation of the computing system will result in movement thereof to a new meta-dynamic state. It is determined that the new meta-dynamic state is undesirable. A path is determined. The path causes the computing system to move back to a desirable meta-dynamic state. The computing system is caused to move on the path to the desirable meta-dynamic state.

Abstract: It is decided whether to adjust data associated with a decoder. In the event it is decided to adjust the data associated with the decoder, the data is adjusted to obtain adjusted data and decoding is performed on the adjusted data. In the event it is decided to not adjust the data associated with the decoder, decoding is performed on the data associated with the decoder.

Abstract: A set of techniques is described for monitoring and analyzing crashes and other malfunctions in a multi-tenant computing environment (e.g. cloud computing environment). The computing environment may host many applications that are executed on different computing resource combinations. The combinations may include varying types and versions of hardware or software resources. A monitoring service is deployed to gather statistical data about the failures occurring in the computing environment. The statistical data is then analyzed to identify abnormally high failure patterns. The failure patterns may be associated with particular computing resource combinations being used to execute particular types of applications. Based on these failure patterns, suggestions can be issued to a user to execute the application using a different computing resource combination.

Abstract: A transmitting unit divides a transmit data into a plurality of code blocks, and encodes each of the plurality of code blocks to generate a transmission signal. The transmitting unit transmits the transmission signal, and a receiving unit receives the transmission signal as a reception signal. The receiving unit, when being an error in the reception signal, transmits a retransmission request feedback data which contains a NACK data and a data indicating the first code block group to the transmitting unit. First resources are assigned for each of the plurality of code blocks of the transmission signal. The transmitting unit assigns resources of the first code block group of the plurality of code blocks of the transmission signal to second resources which are fewer than the first resources, based on the retransmission request feedback data, and retransmits the transmission signal to the receiving unit.

Abstract: Methods, apparatus, and computer-accessible storage media for remotely monitoring and diagnosing storage gateways. Status information may be collected locally on the gateways and uploaded to a service provider via gateway-initiated connections. The uploaded information may be stored to status data store(s). Status proxy(s) on the provider network may analyze the information in the status data store(s) for one or more gateways to detect error conditions on individual gateways or patterns or error conditions on multiple gateways. Upon detecting an error condition on a gateway, the proxy may alert another process, for example an administrator process on the local network that includes the respective gateway. The other process may then message the gateway to address the condition. Information for particular gateways may be provided to clients on request. Information collected from multiple gateways may be viewed and analyzed by the service provider to detect patterns related to gateway design.

Abstract: A health services module can test availability of one or more applications installed in a virtual machine that is instantiated from a backup image of a virtual machine disk file. A health services module can be installed on a virtual machine to test one or more applications that a user wishes to validate. If the health services module indicates that the application(s) of the virtual machine are available, a guarantee of availability can be provided for the backup image of the virtual machine disk file. If the health services module indicates that the application(s) of the virtual machine are unavailable, no guarantee of availability can be given. The guarantee of availability can indicate that the backup image of the virtual machine disk file can be successfully restored, and that the application(s) of the virtual machine instantiated from the backup image are available to respond to a client request.
