    Abstract: Systems and methods utilizing available storage space within a storage system (e.g., as “supplemental” storage) and/or implement less physical storage space in the storage system (e.g., reduced storage overhead) through operation of fragment pre-storage techniques are disclosed. Such fragment pre-storage utilization of the aforementioned available storage space may provide operation emulating larger storage overhead than is actually provided in the storage system, facilitate improved repair rates, and/or facilitate reduced repair bandwidth in the storage system according to embodiments. A fragment pre-storage repair policy may implement source object repair whereby additional fragments for the source object are pre-generated and pre-stored in the storage system as transient fragments, whereby the transient fragments are moved to corresponding storage nodes when those storage nodes become physically present in the storage system.

    Abstract: Various embodiments enable managing data requests made by a receiver device for delivery of content segments to the receiver device. A processor may determine a first number of first chunk requests including a first amount of data requested for a content segment. The processor may send the first chunk requests to one or more servers and may receive first data responses at a receiving rate. The processor may determine whether sufficient data responses might not be received by the receiver device in time to recover the content segment by a time deadline associated with the content segment. In response to determining that sufficient data responses to the first chunk requests might not be received by the time deadline, the processor may determine a second number of one or more second chunk requests for the content segment and a second amount of data to request from the one or more servers.

    Abstract: A client device presents streaming media and includes a stream manager for controlling streams, a request accelerator for making network requests for content, a source component coupled to the stream manager and the request accelerator for determining which requests to make, a network connection, and a media player. A process for rate estimation is provided that will react quickly to reception rate changes. The rate estimator can use an adaptive windowed average and take into account the video buffer level and the change in video buffer level in a way so to guarantee that the rate adjusts fast enough if there is a need, while keeping the windowing width large (and thus the measurement variance) large. A guarantee might be that when a rate drop or rise happens, the estimator adjusts its estimate within a time proportional to a buffer drain rate or buffer fill level.

    Abstract: Embodiments provide methodologies for reliably storing data within a storage system using liquid distributed storage control. Such liquid distributed storage control operates to compress repair bandwidth utilized within a storage system for data repair processing to the point of operating in a liquid regime. Liquid distributed storage control logic of embodiments may employ a lazy repair policy, repair bandwidth control, a large erasure code, and/or a repair queue. Embodiments of liquid distributed storage control logic may additionally or alternatively implement a data organization adapted to allow the repair policy to avoid handling large objects, instead streaming data into the storage nodes at a very fine granularity.

    Abstract: Aspects of this disclosure generally relate to a method of retrieving video data of multimedia content. In an example, the method includes determining a first interval between switch points for a first representation of the multimedia content and a second interval between switch points for a second representation of the multimedia content, wherein the first interval is less than the second interval. The method also includes, based on the determination, submitting one or more network requests for an amount of video data from the first representation that has a playback time that is at least equal to a playback time between switch points in the second representation. The method also includes, after submitting the request for the amount of video data from the first representation, retrieving video data from the second representation.
