摘要： In certain, currently available data-storage systems, incoming commands from remote host computers are subject to several levels of command-queue-depth-fairness-related throttles to ensure that all host computers accessing the data-storage systems receive a reasonable fraction of data-storage-system command-processing bandwidth to avoid starvation of one or more host computers. Recently, certain host-computer-to-data-storage-system communication protocols have been enhanced to provide for association of priorities with commands. However, these new command-associated priorities may lead to starvation of priority levels and to a risk of deadlock due to priority-level starvation and priority inversion. In various embodiments of the present invention, at least one additional level of command-queue-depth-fairness-related throttling is introduced in order to avoid starvation of one or more priority levels, thereby eliminating or minimizing the risk of priority-level starvation and priority-related deadlock.

摘要： A method performed by one or more processors for segmenting and encoding media content over a network. The media content is first partitioned into an ordered sequence of media segments. Each of the media segments is then encoded (i) at a first bit rate to generate a respective one of a first set of data segments, and (ii) at a second bit rate to generate a respective one of a second set of data segments, wherein data segments of the first set may be used interchangeably with data segments of the second set to facilitate continuous playback of the media content. A request for the media content is then received from another device in the network. In response, a respective one of the first set of data segments or the second set of data segments is selectively transmitted, for each of the media segments, based at least in part on a network bandwidth of the first device.

摘要： A network troubleshooting framework is described. In an implementation, a method includes forming a plurality of reports by a plurality of nodes in a network, wherein each of the reports is formed by a respective one of the nodes and includes trace data obtained from the respective node and another of the nodes. An inconsistency is detected in the trace data in one of the reports when compared with corresponding trace data in another of the reports. A set of the nodes is found that formed one or more of the reports having the inconsistency in the trace data.

摘要： Embodiments include methods, apparatus, and systems for prioritizing input/outputs (I/Os) to storage devices. One embodiment includes a method that receives an input/output (I/O) command having a group number field and a priority number field at a target device. The method then generates a new priority value based on the group number field. The I/O command is processed at the target device with the new priority value.
