    Abstract: A method for cross-domain service optimization is implemented on a computing device and includes defining at least one key quality indicator (KQI) target for at least one end-to-end (E2E) service, where the at least one E2E service crosses more than one domain of a communications network, receiving an indication of quality of experience (QoE) for the at least one E2E service, based on the indication of QoE, translating the at least one KQI target to at least one set of service optimization instructions for each domain from among the more than one domain, and for each domain, applying the service optimization instructions.

    Abstract: Statistical remultiplexing of adaptive bit rate streams may be provided. First a video quality associated with a first representation of a content stream being delivered to a first client on a shared network may be determined. The content stream may be available in a plurality of representations, each representation comprising a plurality of chunks of varying sizes and a manifest having an indication of a quality level and a bit rate for the representation. Next, network conditions may be analyzed to determine whether a bit rate of the content stream being delivered to the first client device should be adjusted to adjust the video quality. Based on the determined video quality and the network conditions, it may then be communicated to the first client device to request a second representation of the content stream.

    Abstract: Constant quality video encoding with encoding parameter fine-tuning may be provided. First, an aggregation window comprising a plurality of video frames from a transport stream may be determined. Next, a plurality of video quality values may be determined where the plurality of video quality values indicate a video quality for corresponding respective ones of the plurality of video frames in the aggregation window. Then a determined conformance rate value for the aggregation window may be determined. The determined conformance rate value may indicate a number of the plurality of video quality values that have one of the following characteristics: equal to the target video quality value and greater than the target video quality value. The determined conformance rate value may then be used to adjust at least one of the encoding parameters used in the constant quality encoding of the source.

    Abstract: Various implementations disclosed herein enable client devices to share a network resource in order to produce more evenly distributed perceptual playback quality levels within each subscription tier. Sharing of a network resource is facilitated by providing client devices with one or more QoE distribution indicator values, which enables client device participation in the allocation of the network resource. In some implementations, a client device method includes determining a local QoE level value, and then modifying a representation selection of media content data based on the local QoE and one or more QoE distribution indicator values. The local QoE level value characterizes perceptual playback quality of media content data received by the client device using the shared network resource. The QoE distribution indicator values characterize at least in part the relative QoE values associated with a plurality of client devices sharing the shared network resource with the client device.

    Abstract: Previously known network management methods are incapable of concertedly managing respective levels of perceptual playback quality of media content data for a number client devices. In particular, previously known methods fail to regulate ABR-enabled client devices and the like that are each operating to individually consume as much of one or more shared network resources as possible without regard to the degree performance improvements. By contrast, various implementations disclosed herein provide network-centric concerted management of respective levels of perceptual playback quality of media content data on each of a number of client devices. The respective levels perceptual playback quality are concertedly managed by adjusting one or more shared network resources (e.g., bandwidth, processor time, memory, etc.). Adjustments are made in response to an aggregate quality of experience (QoE) metric characterizing a distribution of QoE levels for the client devices sharing the one or more shared network resources.

    Abstract translation: 以前已知的网络管理方法不能一致地管理多个客户端设备的媒体内容数据的感知回放质量的各个级别。 特别地，先前已知的方法不能调节启用ABR的客户端设备等，其各自操作以独立地消耗尽可能多的一个或多个共享网络资源，而不考虑度数性能改进。 相比之下，本文公开的各种实施方案提供了以多个客户端设备的每一个为媒体内容数据的感知回放质量的各层级的网络中心的一致管理。 通过调整一个或多个共享网络资源（例如，带宽，处理器时间，存储器等）来一致地管理各个级别的感知回放质量。 响应于总体体验质量（QoE）度量来表征对于共享一个或多个共享网络资源的客户端设备的QoE级别分配的调整。
