摘要： An apparatus and method for transmitting and receiving control data and user data between multiple communication stations using multiple backhaul links in a communication system, in which a Multi-Link Relay Station (MLRS) generates multiple backhaul links for data transmission/reception between multiple communication stations, and provides a multi-homing service for mobile stations using the generated multiple backhaul links. The MLRS may also support a handover for mobile stations using the multiple backhaul links. The use of multiple backhaul links facilitates efficient transmission/reception of control data and/or user data between multiple base stations or multiple relay stations.

摘要： Methods to dynamically improve soft real-time task performance in virtualized computing environments under the management of an enhanced hypervisor comprising a credit scheduler. The enhanced hypervisor analyzes the on-going performance of the domains of interest and of the virtualized data-processing system. Based on the performance metrics disclosed herein, some of the governing parameters of the credit scheduler are adjusted. Adjustments are typically performed cyclically, wherein the performance metrics of an execution cycle are analyzed and adjustments may be applied in a later execution cycle. In alternative embodiments, some of the analysis and tuning functions are in a separate application that resides outside the hypervisor. The performance metrics disclosed herein include: a “total-time” metric; a “timeslice” metric; a number of “latency” metrics; and a “count” metric. In contrast to prior art, the present invention enables on-going monitoring of a virtualized data-processing system accompanied by dynamic adjustments based on objective metrics.

摘要： The present disclosure is based on a multi-core or multi-processor virtualized environment that comprises both time-sensitive and non-time-sensitive tasks. The present disclosure describes techniques that use a plurality of criteria to choose a processing resource that is to execute tasks. The present disclosure further describes techniques to re-schedule queued tasks from one processing resource to another processing resource, based on a number of criteria. Through load balancing techniques, the present invention both (i) favors the processing of soft real-time tasks arising from media servers and applications, and (ii) prevents “starvation” of the non-real-time general computing applications that co-exist with the media applications in a virtualized environment. These techniques, in the aggregate, favor the processing of soft real-time tasks while also reserving resources for non-real-time tasks. These techniques manage multiple processing resources to balance the competing demands of soft real-time tasks and of non-real-time tasks.
