    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 said each domain, applying the service optimization instructions.

    Abstract: Various implementations disclosed herein enable a more efficient allocation of one or more shared network resources amongst a plurality of client devices based on media content complexity and client device resource status in order to better manage perceptual playback quality. In some implementations, a method includes obtaining a plurality of resource constraint values associated with a plurality of client devices sharing a network resource, and jointly determining a respective encoding rate level selection and a corresponding resource allocation for each of the plurality of client devices based on a combination of one or more resource constraint values and the assessment of the respective perceptual quality level values, such that a combination of resulting quality levels satisfies a joint quality criterion.

    Abstract: Previously known network management practices fail to inform network operators about client-side performance and experience issues. By contrast, various implementations disclosed herein include systems, methods and apparatuses that generate one or more shared-resource traffic quality indicator values. Each shared-resource traffic quality indicator value characterizes at least a portion of the network by assessing a number of network performance characterization values in relation to one or more capacity values of one or more shared network resources. Each network performance characterization values provides a corresponding quantitative characterization of a quality of experience associated with the use of media content data received by a respective client device. In some implementations, quality of experience is characterized by at least one of an indication of perceptual quality of media content data and an indication of continuity with which media content data is used by a respective client device at a particular subscription tier.

    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: In one implementation, a method performed by a client device includes: determining a perceptual characterization metric, where the perceptual characterization metric provides a quantitative characterization of factors that determine quality of experience associated with a first playback profile of media content presented by the client device; and normalizing the perceptual characterization metric based on characterization factors associated with the client device. The method further includes: obtaining an aggregate perceptual characterization metric that is based at least in part on the normalized perceptual characterization metric from the client device and one or more other perceptual characterization metrics from other client devices sharing at least one network resource with the client device; and determining whether to change the first playback profile based on a function of the first normalized perceptual characterization metric and the aggregate perceptual characterization metric.
